Re: Technical Specs
You can rely on MVCL to operate the way the POP says it will. My impression from reading the POP is that the MVCL is an interruptible instruction so if you're coding first level on a multi processor configuration without an operating system to manager things for you the results of the MVCL can be erractic in appearance even if the instruction has done exactly what it was supposed to since another thread on another processor was updating the storage the MVCL was operating on. I haven't dug this piece of PoP out for some time, but memory suggests that the interruptibility of MVCL has little to do with it, apart from increasing the window. Even instructions like MVC can cause garbling if two sharing processors hit the same piece of storage at the same time. Older machines used to store a doubleword at a time - do modern designs do a conceptual full-length store at one time? ISTR PoP saying the results of two processors trying to update the same storage at the same time would always be unpredictable. -- Phil Payne http://www.isham-research.com +44 7785 302 803
AW: LVM Help
please do man vgcfgrestore
I always had success restoring the vg configuration. this should help.
Please take a look at /etc/lvmconf/
you should run vgcfgbackup from time to time and then you will find old vg
configurations.
then you can restore lvm vg information with:
Example: restore vg information for volume group vgDATA
MYVG=vgDATA
pvscan|grep $MYVG|awk -F'' '{ print $2 }'|while read MYDEVICE
do
vgcfgrestore -f /etc/lvmconf/${MYVG}.conf.1.old -n $MYVG $MYDEVICE
done
also copy this older configurations to another server or use a backup tool
to keep this files save.

Betreff: LVM Help
Yesterday I was trying to expand an existing LVM filesystem and it
appeared ok after I issued the resize2fs command but after I rebooted
the Linux instance the filesystem was mounted but it was not the correct
file system. It appears LVM got the expanded file system confused with
another file system. In trying to correct this problem I think I
corrupted another file system. When I issue a vgdisplay command I get
the following:
vgdisplay -- ERROR: VGDA in kernel and lvmtab are NOT consistent;
please run vgscan
I ran vgscan but it didn't help. I found what appeared to be backups
of volume group information in /etc/lvmconf directory. Is there a way
to recover the LVM to a previous state or recover the volume group info?

EMC acquires VMWare
From today's NY Times (free subscription required): http://www.nytimes.com/2003/12/16/technology/16soft.html The EMC Corporation took a significant step to broaden its business yesterday with the purchase of VMware for $635 million in cash. The purchase of VMware, analysts say, is part of the shift under way at EMC to become less dependent on data storage systems and to expand further into software as price pressures steadily erode the profitability of computer hardware.
Re: Technical Specs
I wonder what the significance of being interruptible is if not garbling results. MVCL came along with System/370 - at that time uniprocessors were more common and a lot of IBM hardware had strict timing considerations - 1419 interrupts HAD to be handled within so many milliseconds or you lost the document - sometimes literally. So an instruction with a potentially long duration HAD to be interruptible for I/O interrupts to be handled in time. I'm not sure what the current situation actually is - the time-critical peripherals have gone and most systems are multi-CPU with the SAP offloading a lot of I/O processing. I doubt that MCVLs get interrupted much these days. I imagined that MVC was atomic in nature meaning that the second processor couldn't garble things until the MVC had run it's course. I think that's implementation-dependent, as IBM would say. Unwise to rely on it. -- Phil Payne http://www.isham-research.com +44 7785 302 803

Re: LVM Help
It shouldn't be needed. When we ran into this, it didn't do any damage, we just ended up with the same filesystem mounted in two places. The usual cause of the problem is a device missing from the configuration. LVM won't activate an incomplete VG, but instead of giving an error, it mounts the wrong one later. Fixing the underlying problem and activating the VG usually straightens things out. SLES8 WILL give an error trying to mount an LV in an inactive VG. This usually halts the IPL process at the local filesystem mount point, while the root FS is still in read-only mode. You can re-ipl without causing damage from here. Of course, if you have to fix fstab at this point, it's a little difficult, but the error messages give a hint about how to remount / read-write. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of Beth Somers Sent: Tuesday, December 16, 2003 9:08 AM To: [EMAIL PROTECTED] Subject: Re: [LINUX-390] LVM Help I noticed you had two responses.

Subject to the documented initial conditions, MVC and MVCL will have consitency on each 4 or 8 bytes that are read and written. That means that the storage access to those locations is serialized and other CPUs will observe storage changing in 4- or 8-byte increments. As another example, (assuming 390 architecture mode) if you load all 16 registers with Load Multiple, and the operand address is on a word boundary, then registers will be loaded 2 at a time (doubleword) with consistency.

Re: Technical Specs
This reminds me: I remember that back when Amdahl was trying to get their Unix system working on the 580 dual processor they had problems with the MVCL. Actually I think this is why I knew that MVCL was a problem in multiprocessor systems. It may be that Amdahl didn't implement MVCL properly. There were some variances between IBM hardware and Amdahl hardware. The UTS group also had problems with the implementation of channels on the 580 and the asynchronous terminal controller (not the 3270 controller). I don't remember much detail, but it had to do with when interrupts occurred. When testing UTS under VM it worked, but when running native it failed. Sometimes VM can mask these kinds of problems. -Original Message- From: Phil Payne [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 16, 2003 5:15 AM To: [EMAIL PROTECTED] Subject: Re: Technical Specs I wonder what the significance of being interruptible is if not garbling results.

Re: Patch to glibc
Mmmm, no, I don't think so. I really want the Linux/390 folks in Boeblingen to figure out what would be the correct fix for this. After I sent the patch, I re-read Ulrich's post much more closely, and re-discovered his thought that the correct way might be to introduce another makefile variable to handle this value for just the .oS files. My patch just blanketly replaces fpic with fPIC for _all_ compilations that used the existing variable. I don't know if that is desirable or not, so I went back and changed my original fix to not do that, and instead updated the Makeconfig file. Since I am in no way a C/C++ developer, I don't want to send possibly boneheaded fixes to someone unfamiliar with Linux/390.

Re: quick vm question
Chris, 1) If you use DirMaint, the backup directory is a flat file on DIRMAINT 1DB. The systems programmer usually sets up one or more userids that can link to other minidisks without using a link password. 2) If you back up your directory, restore it to another disk that you can link to. 3) Does your stand-alone test system use a copy of the production system? If so, check the directory there.

I'll add a related note: SAS/Connect enables a process on one host to initiate SAS processing on a different host (assuming that host has a SAS/Connect listener running). If you *do* get a SAS beta for Linux/390, you may want to look into that. If, for whatever reason, you *don't* get SAS running on Linux/390, you might still be able to offload some CPU load to a SAS host on a different platform (Linux/Intel, UNIX, Wintel, etc.)

This interesting little tidbit showed up today. It says that the per-CPU licensing for SLES8 on iSeries and pSeries is being changed to per-install. (The announcement also uses the term per-server install.) Perhaps someone from IBM could comment on this. Does this mean that if someone uses the hypervisor to create (for example) 10 Linux LPARs, they would be charged for 10 licenses, when they might have been charged much less on a per-CPU basis?

Re: LVM Help
That's exactly what we saw. You shouldn't have to do anything. Most likely a physical volume is missing from the inactive VG. If you can get all volumes properly online, the next time the system boots, it should be back to normal. Another possibility is that one physical volume in the VG has been stepped on, and the signature is no longer valid. Try running pvscan to see if they all look reasonable. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of David Holt Sent: Tuesday, December 16, 2003 4:13 PM To: [EMAIL PROTECTED] Subject: [LINUX-390] LVM Help In this case LVM apparently got the LV from the following VG.

Re: FW: IBM iSource -- U.S. Announcements
Given the gasps that SUSE and Red Hat's per-processor charge generate now (compared to their other prices) I don't think they can sanely go the per-box route there. The price they would need to charge would turn people off because most of them wouldn't be willing to do the work to figure out what that would mean to them on a per-instance basis. If they could even figure out how many instances they'd be able to get on one box.

Re: FW: IBM iSource -- U.S. Announcements
The current model is a per processor charge on the zSeries. You can run as many instances off of a single processor on the box without having to purchase extra copies of Linux. So, if you have a single IFL you purchase one copy of SLES and run as many instances as you want. If you have 2 IFLs, you have to purchase 2 copies of SLES. - Kevin (Embedded image moved to file: pic13031.jpg) PLEASE NOTE NEW CONTACT INFORMATION!

IBM Communications Server for Linux on zSeries
IBM is making IBM Communications Server available for Linux on zSeries as a PRPQ. Contact your IBM zSeries or Linux specialist for information on this PRPQ. There will be information on this product available soon at http://www.ibm.com/software/network/commserver/ . The IBM Communications Server for Linux on zSeries V6.0.1 can meet requirements for interconnecting diverse networks and consolidation of communications workload. With this product,workstation users and applications can communicate with other workstations and other central computer applications, independent of the networking protocols used in each system. It can help users communicating with each other in networks of all sizes, from small workgroups to large corporate headquarters. Communications Server for Linux on zSeries V6.0.1 is based on a common code base with IBM Communications Server for AIX(R) V6.1, and includes the same industrial-strength features and functions you have come to rely on for your mission-critical, core business applications. These features and functions of Communications Server have been well proven in the OS/2(R), AIX, and Windows((R)) environment across a wide variety of server systems -- from relatively small, single-processor systems, through high-end multi-processor systems. In addition, Communications Server for Linux on zSeries has the advantage of running in the zSeries hardware. Some benefits of this include residing in the same box as Communications Server for z/OS, using hipersockets within the box for high bandwidth connectivity. This also increases security by limiting data flow outside the box. Communications Server for Linux on zSeries V6.0.1 capabilities include: - A full-function SNA gateway - TN3270E Server - Telnet redirector - SSL data encryption - Advanced Peer-to-Peer Networking (APPN),including both end node and network node - Dependent LU Requester (DLUR) - High Performance Routing (HPR) - Enterprise Extender (HPR over TCP/IP) - Branch Extender - Support for Ethernet and Token-Ring connections - A rich set of application programming interfaces (APIs) - LUA, including both RUI and SLI interfaces (LU0,LU1,LU2,LU3) - APPC - CPI-C - Java for CPI-C (JCPI-C) Communications Server for Linux on zSeries V6.0.1 is the solution for companies migrating to the Linux platform that: - Run multiprotocol or multiple networks - Have existing SNA applications that they want to extend over TCP/IP networks - Want to: - Improve data security over the Internet/intranet while improving network availability - Use Branch Extender or Enterprise Extender advanced networking technologies to implement more cost effective networks - Consolidate or change their backbone networks - Provide SNA 3270 host access to TCP/IP users - allow VM and VSE SNA applications to be reached through IP via EE - move the TN3270E server function within the zSeries without major definition rework. Such a move will allow TN3270 traffic to flow over an IP network -- versus SNA -- to the data center - use the TN Redirector function within the box to avoid opening extra firewall ports - consolidate all servers onto a single box - take advantage of excess capacity on zSeries - run multiple Linux images on z/VM to take advantage of zSeries benefits such as sharing of processors and memory Jim

Hmmm...there is confusion here, so I sent this thread to Suse and asked them to clear it up here on the list server. I am a big Suse fan and would hate for the wrong message being sent out. (Including from me.) Again, as I understand it, you can have Suse installed on a box with up to x CPUs and run as many instances of Linux as you can on that box. Here is an out-take from the Suse 2004 price list (which does not yet contain zSeries pricing, BTW) I work with Suse on a daily basis and I have not been told of a shift to LPAR based pricing similar to Red Hat's. (Of course if they have, I'l feel real stoopid!) Enterprise Server 8 for IBM pSeries, evaluation version, incl. 3 months Maintenance Program for 1 server (up to 8 CPUs each) and Installationkit ,International (German, English) This is confusing wording, but from what I understand there is no per LPAR charge. Now far be it for lil' ol' me to disagree with Jim. :) Hence, I sent the thread to Suse and told them they should get up on the list server post haste and clear the fog.
