Re: Cif mount
Hi Peter, I'm not sure if you ever got this working, but I thought I'd add a couple of thoughts just in case. Your questions touched upon two different topics, and they each have their own answers: 1.) Is there a way to permit access to more than one user for a CIF mount ? As Aria mentioned, this can be accomplished by setting the UID/GID of the mount point. For example, you could mount the Windows share with a specific group ID, then ensure each user you want to access the mount point belongs to that shared group. The important differentiator is that the root user mounts the CIFS share once, then multiple users can access it. As an alternative approach, you can use the credentials method that Aria mentioned, or perform a multi-user mount. For reference, here's how to set that up: Steps for RHEL: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/storage_administration_guide/mounting_an_smb_share (see section 9.2.4 "Authenticating to an SMB share using a credentials file") (see section 9.2.5 "Performing a multi-user SMB mount") Steps for SLES: https://www.suse.com/support/kb/doc/?id=16706 2) Is it possible to mount cif with multiple uid at once ? ... I mean authority based mount where we specify UID while doing mount This is something that the Gnome desktop does. Using the Nautilus file browser, you can connect to a Windows share, provide your user credentials to access the share, and the mount point appears "automatically" on your desktop. You don't need Gnome to accomplish this, but instead you can use the underlying component (fuse, which stands for "filesystem in userspace") to do the same thing from the command line. The end result is that each user can mount the Windows share using their own credentials, and multiple users can have it mounted simultaneously. If you don't have a Gnome desktop installed, you'll need to install a few required packages. The following package names are based on RHEL, so may need some tweaks for other Linux distributions, but it should be very similar: - gvfs-fuse: This provides the Fuse daemon for creating the mount point "automatically" - gvfs-smb: Allows mounting CIFS shares through Fuse - dbus-x11: This provides a binary called "dbus-launch" that you'll need before mounting the CIFS share Once these are installed, you can use "gio" to mount the Windows share. Here are the steps with comments: ### Install package dependencies # yum install gvfs-fuse gvfs-smb dbus-x11 ### Change to the user you'd like to mount, "myuser" for example # su - myuser ### Create a dbus-enabled shell. Otherwise you'll get errors similar to "volume doesn’t implement mount" $ dbus-launch bash ### Mount the CIFS share. Provide the user credentials on the commandline $ gio mount smb://servername/sharename User [myuser]: Domain [SAMBA]: Password: ### Optional, list info about the share $ gio mount --list --detail ### At this point, your mount point is accessible from the .gvfs directory in the user's home directory. ### FYI if you are running a Gnome desktop, the mount point is in /run/user/ $ ls ~/.gvfs smb-share:server=servername,share=sharename ### Unmount the share $ gio mount -u smb://servername/sharename So it really comes down to which user should mount the Windows share, the root user or the normal user, because there are different answers for each. Hope this helps and isn't totally off base from what you were asking. -Brad --- Brad Hinson Principal Solution Architect Red Hat <https://www.redhat.com/> bhin...@redhat.com M: 919-360-0443 <https://www.redhat.com/> On Mon, Apr 20, 2020 at 5:32 AM Peter wrote: > I mean authority based mount where we specify UID while doing mount > > On Mon, 20 Apr, 2020, 4:14 PM Aria Bamdad, wrote: > > > I don't understand your exact need but through the credentials= option > and > > multiple credential files, you can provide for a series of different user > > name/password pairs. > > > > -Original Message- > > From: Linux on 390 Port On Behalf Of Peter > > Sent: Sunday, April 19, 2020 12:59 PM > > To: LINUX-390@VM.MARIST.EDU > > Subject: Re: Cif mount > > > > Thank you > > > > Is it possible to mount cif with multiple uid at once ? > > > > On Thu, 16 Apr, 2020, 5:54 PM Aria Bamdad, wrote: > > > > > Peter, > > > > > > I don't know if your windows file server is a Samba also or it is > > actually > > > a windows server.

Re: LVM thin provisioning
Hi Marcy, LVM thin provisioning is pretty new, and it's only in the last year that it's been introduced in various distros (as well as OpenStack). I would guess there aren't a huge number of production rollouts right now. But with that said, I know that we have some folks kicking the tires in test environments. We're also seeing it pop up in other open source projects, like Docker, who uses it to replace their AuFS (unionFS) dependency: https://www.docker.io/ http://blog.docker.io/2013/09/red-hat-and-docker-collaborate/ I think we'll see more of LVM thin provisioning as it gets further baked in the enterprise world. Meanwhile, as others have mentioned, thin provisioning at the storage level can accomplish many of the same things. However, LVM is storage-agnostic, and is a great compliment to LVM snapshots if you use those. I'd say check it out when you get a chance. -Brad Brad Hinson Solution Architect, Red Hat +1 (919) 360-0443 On 12/04/2013 06:22 PM, Marcy Cortes wrote: This is now available as of SLES 11 SP3.

HyperPAV and LVM striping
Hi folks, What are the best practices for HyperPAV and LVM striping? I assumed that if you have HyperPAV enabled, you don't need to stripe the data. Is this true, or if not, what is the best practice for optimum performance? I have lots of mod-9 ECKD with HyperPAV enabled, so I want to use LVM. So my two choices are standard LVM, or LVM striping. If I stripe across the disks I spread the I/O across the physical volumes, but my gut tells me I shouldn't have to do this, since HyperPAV is moving around aliases dynamically. For example, say I have 2 PVs and 4 HyperPAV aliases. If I send some heavy I/O through the Linux (device-mapper) block device, then I would assume: - #1, for the case with LVM striping enabled, LVM will spread the I/O to both PVs, and HyperPAV will assign 2 aliases to each PV since I'm banging on them both. - #2, for the case without LVM striping, HyperPAV will assign 4 aliases to the first PV since that's the only one in use. In either case, it seems I'm using all 4 aliases, so seems like I would get the same performance. Please correct me if I'm wrong. And if so, which of these configs is better? Lastly, is there a presentation or doc that talks about how to enable HyperPAV in Linux, or is bringing the HyperPAV aliases online enough to trigger the dasd driver to do the right thing?

Change your command to: DEFINE STORAGE AS 700M STANDBY 300M As was discussed in another thread, reserved storage is memory that may become available (either to your virtual machine or to an LPAR) but is not currently available. Standby storage *is* available and can be dynamically added to your virtual machine or to an LPAR.

Re: persistent zfcp ports/luns
Hi, Try running mkinitrd with --with=zfcp. It forces mkinitrd to include the new version of /etc/zfcp.conf in the new initrd. And just for completeness, make sure to run zipl afterwards, otherwise the old LUNs will appear along with the new ones - the old ones come from the initrd and the new ones come from /etc/zipl.conf. Now that I think about it, that's more likely the issue. Could the zipl step be missing? -- Brad Hinson bhin...@redhat.com Worldwide System z Sales, Strategy, Marketing Red Hat, Inc. +1 (919) 360-0443 http://www.redhat.com/z On Feb 29, 2012, at 6:44 AM, Offer Baruch wrote: Sorry...

I though the script zfcpconf.sh is run at startup using the 56-zfcp.rules* *udev rule and that is it... as all 56-zfcp.rules* *does is run zfcpconf.sh i can't figure out where did the system get the old luns/ports? I suppose this is RHEL 5: You may need to regenerate your initrd after modifications to /etc/zfcp.conf since this gets added to the initrd, IIRC. On reboot, your old initrd containing the old zfcp.conf still activates the old WWPNs and LUNs before the root-fs gets mounted. (All this differs for RHEL 5, RHEL 6, SLES 10, SLES 11.) zfcpconf.sh just reads /etc/zfcp.conf That adds the new WWPNs and LUNs after the root-fs was mounted.

Also make sure the initrd was transferred completely. I've seen this error when the FTP session had a hidden error that the disk was full. Check query disk to make sure the 191-a disk isn't at 100% usage. If you login to the guest and run the 'filelist' command, you'll see the record length (LRECL) and the number of records (RECORDS) for the initrd. The LRECL for the initrd should always show 80, and if you tell me which update of RHEL 5 you're installing I can give you the expected number of records, to make sure the file was transferred correctly. For example, the RHEL 5.7 initrd is 132080 records, and the RHEL 5.6 initrd is 119579 records. -- Brad Hinson bhin...@redhat.com Worldwide System z Sales, Strategy, Marketing Red Hat, Inc. +1 (919) 360-0443 http://www.redhat.com/z On Feb 17, 2012, at 7:49 AM, karlkings...@ongov.net wrote: Make sure that your files that you punch to the reader are FB 80.

Re: LDAP
Hi Erik,
I'm not an LDAP expert, but I know it's changed a lot since RHEL 5. Check
these links:
https://access.redhat.com/kb/docs/DOC-66593
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/ch-Directory_Servers.html#s2-ldap-pam
If that doesn't have what you need, I recommend opening a support call. There
are LDAP specialists who can probably answer that one very quickly.

I have been trying to configure REHL6 on a z114 to authenticate to an Active
Directory Domain Controller with LDAP.
What I was hoping was to be directed to a document or procedure to help me
along.
I think I have it all working but the TLS.
The manuals are very terse. I was also emailed the certificate and the books
are all about downloading the certificate. I am not clear exactly where to
put it or name it.
Thank you!

The tool has worked great but we have noticed something interesting. We are setting up our linux guests with a default amount of storage, along with a max and standby amount. For example, a server may have the following in the directory: STORAGE 1G MAXSTORAGE 16G COMMAND DEFINE STORAGE STANDBY 15G RESERVED 0M When we use the dump device on one of these servers, it dumps all 16G even though only 1G is defined/active! Is this normal behavior for the tool, or should it (can it?) be looking at what storage is active? I wouldn't think so. For it to dump all 16GB, Linux would have to activate the standby memory, but that would be meaningless since it going to be filled with zeroes. Or does it simply *appear* to have dumped all 16GB? Is the dump file actually 16GB? Look at CP Q V STOR before and after the dump. Before the dump I would expect something similar to STORAGE = 1G MAX = 16G INC = 1M STANDBY = 15G RESERVED = 0 If Linux activated the storage, you would see STORAGE = 16G MAX = 16G INC = 1M STANDBY = 0 RESERVED = 0 Alan Altmark Senior Managing z/VM and Linux Consultant IBM System Lab Services and Training ibm.com/systems/services/labservices office: 607.429.3323 mobile; 607.321.7556 alan_altm...@us.ibm.com IBM Endicott I see the same behavior on our system.

cmsfs-fuse package in RHEL 6.1
Hi, Just an fyi for anyone interested in cmsfs. cmsfs-fuse is a new feature included in RHEL 6.1 (released last week) which allows write access to a CMS filesystem. For example, it's now possible to edit files on a guest's 191 disk with a Linux text editor like 'vi'. It's contained in the package 's390utils-cmsfs-fuse', but you won't find it in the normal channels for download with RHEL 6.1 on http://access.redhat.com. Instead, it's in the 'optional' channel for 6.1. For ease, here's a link: https://rhn.redhat.com/rhn/software/packages/details/Overview.do?pid=631604 (redhat.com login required) Some new packages land here by default, but you may see it merged into the normal channels by RHEL 6.2. Please let me know if anyone has trouble getting this new package.

Re: Read-only DASD and CMSCONFFILE
On 02/28/2011 11:42 AM, Philip Rowlands wrote: Short version: DASD='777,888(ro)' is valid and useful CMSCONFFILE, but we don't see that syntax in either the documentation or the script's own output. Long version: Picture the scene; there's a minidisk holding kickstart files and the full RHEL install file set. Other users LINK this minidisk in order to read the data locally. We configure the target and repo dasd with DASD=777,888. What happens next? - The R/O LINK is not detected by the Linux dasd module. /sys/bus/ccw/devices/0.0.0888/readonly is 0. - For reasons unclear to me, anaconda wants to write to all the partition tables it can see, despite having no clearpart, initlabel or partitions defined for that disk. - The kernel logs spews out the usual EXAMINE 24 error and sense hex data seen when you try to write to a read-only disk. - anaconda stalls and prompts to Ignore the error on dasdb, unless we're using non-interactive kickstart, in which case it stalls for good. How to fix this? The CMSCONFFILE read by linuxrc.s390 (the /sbin/init of RHEL's initrd installer image) supports a DASD= parameter, which is sanity-checked and passed to the kernel. Tell linux which minidisks are readonly like this: DASD=777,888(ro) If we follow the RHEL install documentation, or rely on linuxrc.s390's own interactive option p to print out the CONF file, we have a problem. CMSCONFFILE is a shell script, sourced by bash. It must be written in syntax-compliant bash, which DASD=777,888(ro) is not. DASD='777,888(ro)' # quoted to protect the parentheses is correct syntax, and will successfully protect the disk from anaconda's attempts to write to it. I'll probably file this in RHEL Bugzilla, and send a note to IBM's Linux team in Germany, but wanted to post here first for feedback and to see if anyone else has run into similar problems. Cheers, Phil Hi Phil, Thanks for your detective work in tracking down the fix for this. Please do file a RHEL Bugzilla. This should be documented.

Re: How to use FSCK_FORCE_ALL_PARALLEL at boot time
On 01/04/2011 01:35 PM, Donald Russell wrote: RHEL 5 The man pages for fsck say the FSCK_FORCE_ALL_PARALLEL environment variable controls fsck behavior so filesystems residing on the same physical device can actually be checked in parallel as per the /etc/fstab settings. i.e. I have the root file system with fsck pass 1 and all other filesystems as pass 2. The idea being that all pass 2 file systems may be checked simultaneously, though fsck will do them serially if they are on the same devices. The man page doesn't say if a particular value needs to be set, so I assume just the fact the environment variable being defined is enough, so I set it to 1. I also explicitly set FSCK_MAX_INST=0. (Which I may change later if I get this working) But, I don't see all these fscks going in parallel when I boot. I use shutdown -F -r now to force an fsck but they still seem to run serially. I put the values in /etc/sysconfig/init but either that's not the right place, or 1 is not a value fsck deems appropriate. :-) So, where is the correct place and what is the correct value to set these if I want them to take effect when the system is coming up? Thanks very much Hi, Unfortunately /etc/sysconfig/init isn't the right place for that environment variable. It's really only for the variables listed here: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/ch-The_sysconfig_Directory.html#s2-sysconfig-init FSCK_FORCE_ALL_PARALLEL really needs to be set in /etc/rc.sysinit, before fsck is run. So there are a couple of options. 1) Manually edit /etc/rc.sysinit, and change the lines that run fsck (around line 640, search for Checking filesystems). Change: fsck -T -t ... to FSCK_FORCE_ALL_PARALLEL=1 fsck -T -t ... Pros/Cons of this approach: It'll definitely work, but mucking with startup files causes update issues (/etc/rc.sysinit could get overwritten when the initscripts package is updated), and could also cause issues if you call into Red Hat support one day. 2) You can open a support ticket with Red Hat support and request this change. The fix would be to either change /etc/rc.sysinit to support fsck-related environment variables, or edit fsck itself to take this variable as a commandline option instead (probably the better fix, since it's already possible to pass fsck commandline options through a config file -- /fsckoptions). This is the best long-term approach, but doesn't give you a fix today. 3) Okay first off this is an ugly hack I admit. But there are some config files that get read before the fsck in rc.sysinit. One of these is /etc/sysconfig/clock. You could add FSCK_FORCE_ALL_PARALLEL=1 to the bottom of /etc/sysconfig/clock, and theoretically it will be set by the time the fsck runs. The Pro is you'll be fully supported by Red Hat because you're just editing a config file, as opposed to option 1. The Con, well, see the first sentence :) -Brad --- Hey! Hey! You! You!

Re: Kernel panic - not syncing error on Red Hat Linux
In addition to the other great hardware suggestions, on the software side, that's a pretty old kernel version. There are a couple dozen OOM-related fixes in post RHEL 4.4 kernels. I'd recommend sending your sysreport to Red Hat support, so they can tell you the minimum kernel version to use. Or I'd recommend trying the latest RHEL 4 kernel (2.6.9-89). In a way it's good it locks up so often, because you'll know pretty quickly if the new kernel version helps.

Efficient Scheduling * The CFS schedules the next task to be run based on which task has consumed the least time, task prioritization, and other factors. Using hardware awareness and multi-core topologies, the CFS optimizes task performance and power consumption. Filesystems * The new default file system, ext4, is faster, more robust, and scales to 16TB. * NFSv4 is significantly improved over NFSv3, and is backwards compatible. * Fuse allows filesystems to run in user space allowing testing and development on newer fused-based filesystems (such as cloud filesystems). System Resource Allocation * Cgroups organize system tasks so that they can be tracked, and so that other system services can control the resources that cgroup tasks may consume (Partitioning). Two user-space tools, cgexec and cgclassify, provide easy configuration and management of cgroups. ..plus much more. See http://www.redhat.com/rhel/server/details/ for more info on what's new.

Re: Rhel 5.4 install problems
Mark Ver wrote: Try defining a second cpu DEF CPU 02 Or try doing a define stor of 2G or greater. If I recall correctly, there was an issue found with parameter file handling on RHEL 5.4 installer image that required such restrictions. I think this will be documented in an updated release notes if not done so already. But whenever I've seen that problem, I've been able to log on after specifying the network info manually. So it sounds like there is another problem involved here. Also as far as I know, the prompt into the Red Hat installer shouldn't be asking for a password ... is the session just hanging? Or is actually coming back with an access denied message? Another thing to check is the protocol your ssh client (for example PuTTY) is using. It should be ssh protocol 2, not 1. Here are a few things that might be a good place to start debug: 1) see if you can log in as debug instead of root (should also not require a password) 2) if using a Windows ssh client, try logging in from another Linux system with X forwarding explicitly disabled (small x flag) in case X forwarding is causing some sort of disruption in getting the display from the loader program. ssh -x r...@mysystem.net 3) press enter twice on the z/VM console for the guest, this should get it to display a console prompt, ex: sh-3.2# You can then use it to do stuff like: ifconfig tail /tmp/anaconda.log cat /tmp/netinfo cat /etc/passwd ps | grep sshd - Mark Ver -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- Brad Hinson bhin...@redhat.com Sr. Support Engineer Lead, System z Red Hat, Inc.

Hi Marian, That should be FCP_1, FCP_2, and so on. Can they specify them like this?

Re: TCPDUMP
Hi Ron,
This sounds strangely familiar to an issue fixed in libpcap/tcpdump in
RHEL 5.2:
http://rhn.redhat.com/errata/RHBA-2008-0321.html
Under Details section:
* The libpcap library did not work correctly with qeth devices when
layer2 mode was disabled.
Here's the title of the original Bugzilla:
tcpdump does not show outgoing packets with fake_ll=1
I've attached the patch. You may want to contact Novell support to see
if this patch has been included in the versions of libpcap/tcpdump
you're using.

Re: SAR -v command values
Hi Rick, dentunusd shows how many unused directory entries (dentries) you have in the kernel's memory cache. Dentries are stored on disk, and contain information about a specific directory. They're cached in memory for faster access as you change directories. For a rough example, try 'mkidr /tmp/test; vi /tmp/test'. Here's an article on managing this value. I'm sure there are many like it, but this is just one approach: http://rackerhacker.com/2008/12/03/reducing-inode-and-dentry-caches-to-keep-oom-killer-at-bay/ -Brad Rick Truett wrote: Hello, I am looking for an explanation of the value returned in the dentunusd field from the sar -v command.

Re: RHEL install
Hi Thang, Yes, you can definitely install without a CONF file. You would just put everything into the PARM file, and not specify CMSCONFFILE= or CMSDASD=. In fact, this is how it's done with zPXE, the PXE client for cobbler/Satellite. For example, see here: https://fedorahosted.org/cobbler/wiki/SssThreeNinety (sample PARM file towards the bottom) Keep in mind though that the PARM file has an architectural limit of 11 lines (880 characters), so you have to be clever and fit as many parameters on an 80 character line as possible. -Brad Thang Pham wrote: Is there a way to install RHEL on s390x architecture without the need to specify a CONF file and putting the CONF file on a CMS disk? Can I append the configuration onto the PARM file and punch it to reader (which I tried but does not work)? According to Red Hat, A .parm file is still required for the real kernel parameters, such as root=/dev/ram0 ro ip=off ramdisk_size=4, and single parameters which are not assigned to variables, such as vnc. Two parameters which are used in z/VM installs to point the installation program at the new CMS configuration file need to be added to the .parm file: CMSDASD=191 CMSCONFFILE=redhat.conf CMSDASD is the device ID of the CMS formatted DASD which contains the configuration file. CMSDASD is often the 'A' DASD (usually disk 191) of the z/VM guest account. The name of the configuration file must be set with CMSCONFFILE and needs to be all lowercase.

You would just put everything into the PARM file, and not specify CMSCONFFILE= or CMSDASD=. In fact, this is how it's done with zPXE, the PXE client for cobbler/Satellite. For example, see here: https://fedorahosted.org/cobbler/wiki/SssThreeNinety (sample PARM file towards the bottom) Keep in mind though that the PARM file has an architectural limit of 11 lines (880 characters), so you have to be clever and fit as many parameters on an 80 character line as possible. -Brad Thang Pham wrote: Is there a way to install RHEL on s390x architecture without the need to specify a CONF file and putting the CONF file on a CMS disk? Can I append the configuration onto the PARM file and punch it to reader (which I tried but does not work)? According to Red Hat, A .parm file is still required for the real kernel parameters, such as root=/dev/ram0 ro ip=off ramdisk_size=4, and single parameters which are not assigned to variables, such as vnc. Two parameters which are used in z/VM installs to point the installation program at the new CMS configuration file need to be added to the .parm file: CMSDASD=191 CMSCONFFILE=redhat.conf CMSDASD is the device ID of the CMS formatted DASD which contains the configuration file. CMSDASD is often the 'A' DASD (usually disk 191) of the z/VM guest account. The name of the configuration file must be set with CMSCONFFILE and needs to be all lowercase.

Thanks, -Brad After some further digging, this works for me with the line: clearpart --initlabel --drives=dasda,dasdb Note --all is replaced with --drives=. Can you verify this works for you? fyi, the --drives= option is only necessary when the disk is *very* unformatted, i.e. cpfmtxa/cpformat/dasdfmt has never been run on this disk. It was tough to get a disk back into this state after it's been used in Linux, but by using dasdfmt (killed prematurely before if finished), I was able to attach the disk to another guest, and lsdasd showed: 0.0.1000(ECKD) at ( 94: 24) is dasdg : n/f 0.0.1001(ECKD) at ( 94: 32) is dasdi : n/f (with n/f meaning not formatted) Under this situation, --drives is needed. Otherwise, --all --initlabel will do the trick.

Re: Terminal server
Hi, RHEL 5.4 added a TTY terminal server over IUCV. Here's a brief description, copied/pasted from the feature request bugzilla: This implements the terminal server running on a dedicated z/VM guest. The terminal server is a user space program that accepts connections via the normal network and uses the AF_IUCV socket API to provide a console session to the Linux guests of the z/VM system that are enabled for the IUCV console. Note that while the description above mentions 'user space program', there is also an equivalent kernel piece that requires the RHEL 5.4 kernel as well as the RHEL 5.4 s390-utils package. As for documentation, check out the readme here: /usr/share/doc/s390utils-1.8.1/ts-shell/README.ts-shell -Brad Thang Pham wrote: I understand that RHEL 5.4 has a terminal server, is there any documentation about how to install and use it? - Thang Pham IBM Poughkeepsie - -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- Brad Hinson bhin...@redhat.com Sr. Support Engineer Lead, System z Red Hat, Inc.

Yep, this is optional and purely for backup purposes. 2) The mkinitrd -f initrd-$(uname -r).img $(uname -r); assuming uname -r returns the current level of the running kernel, if you're doing several things during a small maintenance window, e.g. - applying patches, adding dasd, and with this scenario existing; You are correct. This command assumes you want to rebuild an initrd for the currently running kernel. If you have multiple kernels installed, or are building an initrd during a maintenance window where your running kernel does not match your production kernel version, you'll have to manually specify the kernel version instead of using $(uname -r).

The reason vmpoff didn't work the first time is that '/sbin/halt' halts the system without doing a true poweroff instruction (thus leaving the system halted but on), whereas '/sbin/poweroff' does a halt+poweroff. 'shutdown -h now' does a poweroff also, which is why that worked the 2nd time. If you have vmpoff=LOGOFF vmhalt=LOGOFF, you have all your bases covered.

You can use these in /etc/fstab, but in your case with LVM, I don't
think it will help, since LVM entries in fstab are of the form
/dev/{volume_group_name}/{logical_volume_name}.
Going back to the original issue, the reason the new disk came up as
dasdg is because you're calling chccwdev/mkswap in /etc/rc.local. As
Adam, Pat, and Mike pointed out, you should use modprobe.conf for all
disks. Either:
options dasd_mod dasd=200-205,700-701
in which case any DASD you add after 701 will be dasdh. Or you could do
something like:
options dasd_mod dasd=200-20f,700-701
The latter is a preallocation of device nodes. You can add any DASD up
to 70f without needing to remake the initrd or rerun zipl.

You could do that, too (preallocate devices for additional VDISK swap).
Depends on whether you're more likely to add ECKD DASD, VDISK swap, or
both in the future.

Re: Documentation on CMM-1 setup?
Hi Pat, Here's the process: 1.) Add 'modprobe cmm' as the last line in /etc/rc.local (then run 'modprobe cmm' to load the module) 2.)

I'm a fan of kickstart - and I'll list my reasons in approximate order of importantance to me (most to least): - kickstart forces a scripted and recreatable installation. You specify the rpm's and can do some limited scripting within the kickstart file itself to end up with (hopefully) a working Linux system that requires no manual tweaking (at least - if you do it 'right'). The alternative is a cloned system that the Linux SA's have been on, and perhaps several other teams - all performing manual tasks to end up with the final product - all sorts of shoeprints and no good detectives. Whereas a kickstart config is self-documenting - a clone is not. With good scripting and good use of rpm packaging for your 'local' or even 'vendor' products - you can end up with a very KISS config file that might even go multiplatform. (e.g. arch=`uname -m` ) - with a proper building of conf and parm files on z/VM - a guest can be kicked already configured with a working network -- no need for some outside scripting or manual config. - you can have different kickstart files for different server 'types' (web, app, db, etc) - these can even be built dynamically and requested via a URL to to the kickstart ( e.g. http://mykicker/kick.webip=xx.xx.xx.xx+etc+etc.) - The size of the DASD can be flexible.. cloning requires copying the same size DASD as the source.. - The latest fixes can be applied by keeping the repository the kickstart uses current - rather than updating a clone source. (of course - testing is still required and would require kickstarting a guest to truly do any testing - a good thing imo) - It encourages packing by rpm rather than manual 'tarball' methods.. this is in line with a 'recreatable' install. Yes, you can still do 'tar' commands in the kickstart file itself.. but specifying an rpm package is oh so much easier. - Servers start 'clean' - ie no old log files from the clone source and no need to try and script a 'cleanup' - No worrying about whether a clone source is 'up' when a new server is clone and possibly clone a live system There are downsides.. but I'll leave those to the rest of you to expound on, since I'm taking a position of 'kickstart good, Jane' Thanks and hope this is valuable to some ..

Re: To kick or to clone ... that is the question
Hall, Ken (GTS) wrote: The small addition of the read time for DDR is nothing compared to the time required to install the packages over the network. That's at least the same amount of reading, plus network time. I agree about the problem of keeping multiple masters. We keep just one per version, and use a first-boot process to install additional packages via yum as needed, or let the admins install what they need manually. It's still faster, by quite a lot. Unfortunately, I don't have time today to run measurements, but our base system clone process takes less than 30 minutes from beginning to end. All this said, we have been seriously considering going to a kickstart based method, but my experience with it has not been encouraging. Aside from taking longer, it seems to be fairly fragile and requires more manual effort. Our clone method consists of running a VM-based dialog, waiting for the copies to finish (run asynchronously in a service machine), and then autologging the new guest. Are you using NFS to host the install tree? In some recent tests, I noticed a huge improvement installing over NFS when tweaking the NFS mount options (rsize, wsize, tcp instead of udp, timeout). In the kickstart file, you'd specify something like this: nfs --server=server.example.com --dir=/path/to/rhel5.3 --opts=tcp,rsize=8192,wsize=8192,timeo=20 These options help especially if there's a lot of traffic on the line.

I'm a fan of kickstart - and I'll list my reasons in approximate order of importantance to me (most to least): - kickstart forces a scripted and recreatable installation. You specify the rpm's and can do some limited scripting within the kickstart file itself to end up with (hopefully) a working Linux system that requires no manual tweaking (at least - if you do it 'right'). The alternative is a cloned system that the Linux SA's have been on, and perhaps several other teams - all performing manual tasks to end up with the final product - all sorts of shoeprints and no good detectives. Whereas a kickstart config is self-documenting - a clone is not. With good scripting and good use of rpm packaging for your 'local' or even 'vendor' products - you can end up with a very KISS config file that might even go multiplatform. (e.g. arch=`uname -m` ) - with a proper building of conf and parm files on z/VM - a guest can be kicked already configured with a working network -- no need for some outside scripting or manual config. - you can have different kickstart files for different server 'types' (web, app, db, etc) - these can even be built dynamically and requested via a URL to to the kickstart ( e.g. http://mykicker/kick.webip=xx.xx.xx.xx+etc+etc.) - The size of the DASD can be flexible.. cloning requires copying the same size DASD as the source.. - The latest fixes can be applied by keeping the repository the kickstart uses current - rather than updating a clone source. (of course - testing is still required and would require kickstarting a guest to truly do any testing - a good thing imo) - It encourages packing by rpm rather than manual 'tarball' methods.. this is in line with a 'recreatable' install. Yes, you can still do 'tar' commands in the kickstart file itself.. but specifying an rpm package is oh so much easier. - Servers start 'clean' - ie no old log files from the clone source and no need to try and script a 'cleanup' - No worrying about whether a clone source is 'up' when a new server is clone and possibly clone a live system There are downsides.. but I'll leave those to the rest of you to expound on, since I'm taking a position of 'kickstart good, Jane' Thanks and hope this is valuable to some ..

After glancing through the code, it appears you can in fact host the kickstart over FTP in RHEL 5, but it must be anonymous FTP. This is a change in behavior since RHEL 4.

Admittedly this isn't a normal situation, but it could come up where there was residual data in the minidisk space, or something crashed. And for Doug's point, by that logic, I can reduce my build time to zero by simply cloning a ready system over every disk instead of formatting. We configure instances on first-boot anyway. But this doesn't work unless you're using full volumes. Those of us using minidisks don't have the option of preformatting, so this becomes an apples-to-oranges comparison. Not sure I follow. On this guest, assuming zerombr yes works and the installer dasdfmt's the disks, after the installation finishes, you can change zerombr to 'no' (or leave it off altogether), and change clearpart to --all only. Then when you install again to the same disks, the dasdfmt will not happen.

To your first point, I think Doug was pointing out that you don't have to do this format every time.

Introducing zPXE, now part of Cobbler
https://fedorahosted.org/pipermail/cobbler/2009-February/002876.html Hi all, Back in July we talked about Cobbler, a standalone install server (see thread Cobbler anyone?). I'm happy to announce Cobbler now has a PXE client for z/VM. Written in REXX, it replaces (or can be called from) your default PROFILE.EXEC, and simulates just about everything a traditional PXE client does, including: - Communicates with PXE server (Cobbler server) to see if this guest should be installed/reinstalled, or - Presents a menu of remote installation sources - Downloads kernel/initrd/parm and punches files to begin install/kickstart - IPLs a specified disk by default (or if logged on disconnected via XAUTOLOG) The really cool part is that this doesn't require a writeable 191 A disk (or any other disk space for that matter), so it can be mass-deployed on a shared read-only space (like LNXMAINT's 192 disk if you follow the Redbooks). For more info on Cobbler, check out: http://magazine.redhat.com/2007/08/10/cobbler-how-to-set-up-a-network-boot-server-in-10-minutes/ https://fedorahosted.org/cobbler/wiki/SssThreeNinety Many thanks to James Laska and Michael DeHaan for all their hard work and Cobbler skills and ideas.

Now that everything's mounted, you can troubleshoot the original problem. If you're being dropped to a repair prompt on normal boot, here are some things to check: - verify all entries in /mnt/sysimage/etc/fstab, but specifically /usr entry. - check /etc/modprobe.conf, dasd= parameter. Especially if any disks have been added/removed/changed recently. - there could be an initrd problem (perhaps the lvm module isn't being loaded?) You can regenerate the initrd with chroot /mnt/sysimage; mkinitrd -v /boot/initrd...img kernel_version - if you make any changes to modprobe.conf or the initrd, chroot /mnt/sysimage, then run zipl. This is good to do anyway, just in case something is out of sync. - unmount /usr and run e2fsck /dev/volumegroup/usr_lv to check the filesystem. This is always a good thing to check, but in your case it's probably not the problem.

I believe that we did find this rpm directory on the DVD, (along with many others), but we were not able to rpm -V it because we do not have any linux (of any distro on any platform) at work. However, I have been given a Solaris Live CD (by the Solaris admins!),but I do not think Sun use rpm packaging method, so I do not think that this would help me. Can you use the Solaris Live CD to boot a system on the same network (possibly a laptop)? If so, one idea is to boot Solaris on the laptop, mount the DVD locally, then share that out via NFS/HTTP/FTP. Then you could perform a network install and point to this system. This assumes though, that you can eject the Solaris Live CD, or you have an external DVD drive though. If not, you can download a Fedora 10 LiveCD: http://fedoraproject.org/en/get-fedora You can boot with the command-line option live_ram. If you have roughly 1 GB RAM or more, this option loads everything into RAM so you can eject the DVD and reuse the drive. Then use that as the NFS/HTTP/FTP installation server. -Brad On my Fedora system at home, I do not have a DVD drive, so I cant rpm -V there.

Re: IPL parms
Does zipl display a boot menu? If so, you'll need to pass root= to zipl, not IPL. For example, at a prompt like this: 00: zIPL v1.5.3 interactive boot menu 00: 00: 0. default (linux) 00: 00: 1. linux 00: 00: Note: VM users please use '#cp vi vmsg input' 00: 00: Please choose (default will boot in 15 seconds): You'll want to enter: #cp vi vmsg 0 %root=/dev/dasdd1 This adds root=/dev/dasdd1 to the Linux kernel parameters. Note: The % is an escape character to '#cp vi vmsg' which sets input to lowercase.

This behavior and the escape character (%) are adjustable at build-time by editing the driver sources, or at run time by use of the ioctl interface. So maybe this default changes by z/VM level (?)

If I have a z/linux guest called ztrash01, I can logon to z/VM as ztrash01, IPL xxx, logon to Linux and shutdown -h now, and if I'm still logged on as console from my 3270 terminal session, enter logoff. No problem. The why I want to do the following is to potentially stress test some applications by forcing off a z/Linux guest (crash) and then eventually trying to automate and re-IPL, but first I gotta be able to do some basic z/VM CP commands below. I read the LOGON in the CP commands and Utilities reference, but I'm doing something wrong (other than trying to trash and stress test my guest). I'm still playing with test systems, but from a z/VM CP perspective, for now the Linux guest ztrash01 is shutdown and halted, but ztrash01 is still logged onto z/VM. 1. If I'm logged on as operator to z/VM, I can issue CP command q n and see that guest ztrash01 is logged onto z/VM and DSC (disconnected). 2. Still as operator, I can issued CP command force ztrash01 logoff immed and this logs the guest, ztrash01, off of z/VM (FORCED BY OPERATOR) 3. Still as operator, a q n verifies that the guest is gone (i.e. logged off z/VM) 4. Now, as operator, instead of going to another z/VM terminal session and logging on as ztrash01, still as operator, I would like to cause the guest ztrash01 to logon (and eventually IPL). To cause the IPL of guest ztrash01 at LOGON, I believe I can put that in the PROFILE EXEC (e.g. IPL xxx) at the end, but how (if at all) can I cause the guest to be logged on (opposite of FORCE) while being logged on to z/VM as operator?

Re: VNC problem
Hi, VNC 4.1.2 should work. Here are a few things to verify: 1. Verify the server is listening on port 5901. From the server, run: # netstat -pan | grep vnc | grep 5901 You should get a result like: tcp 00 0.0.0.0:5901 0.0.0.0:* LISTEN 7123/Xvnc If you see this, the server is up and running. If not, check that the appropriate service/daemon is started and the initial configurations have been done. This varies slightly by distribution, but for a general idea see: http://kbase.redhat.com/faq/FAQ_79_3976.shtm 2. Next, verify the client can reach port 5901 remotely. There are various port scanning applications, but the simplest way is just to use telnet. From the client, run: == telnet servername 5901 (..replacing servername with the VNC server). If it connects, you'll see something like: Trying xx.xx.xx.xx... Connected to server.example.com (xx.xx.xx.xx). Escape character is '^]'. (escape with ctrl+], then 'quit' to exit) If the client fails to connect, then usually the issue is a firewall between the server and client that doesn't allow traffic to port 5901. Check with the network folks, and also check to see if the local firewall is running on the VNC server or client. 3.) And if all else fails, there's one more little gotcha.. on the client, make sure you attempt to connect to server.example.com:1 (emphasis on the colon+1). This tells the RealVNC client to try port 5901. -Brad Stahr, Lea wrote: I have a new SuSE 10 SP1 guest. I have started the VNCSERVER on Linux.

For a slightly different approach, see the RHEL 4 Cookbook at: http://www.redbooks.ibm.com/abstracts/sg247272.html This does cloning from Linux as well, but moves away from the 'dual boot' approach.
