What is causing this error when I use pvcreate? I thought I remembered
seeing something sometime ago about this --? I've used a mknod script I
found on the list, run mkinitrd and zipl -- ?
I'm stuck.

Domino's OK for mail on the 390 platform, but it's no gem for
applications. If you get a chance, try running the app from the
dedicated Windows client against the 390 server and compare results.
Some of the performance difference should go away for the things that
can be offloaded to the client
Obviously I'm joking, but it just seems to me the phrase different horses
for different courses seems to apply in spades here.
And I agree. Perhaps you could make this point to IBM's marketing
department. (And should you have driven this point home with them during
the commercial onslaught
Comparisons between an in house Domino app when run on a 800Mhz Wintel
with 500MB RAM versus a SLES8 zLinux guest machine with 256MB storage and
300MB of VDISK swap on an almost idle 192 MIP IFL show the Wintel box
processing about 3 times faster. The numbers are coming from the Domino
web log.
I haven't followed the list as much as I'd like lately, can someone direct
me to a rebuttal of this:

I have three Linux images coupled to a VSWITCH. The VSWITCH is connected
to an OSA Express. The OSA Express is plugged into a VLAN on a Cisco 6509
which is plugged into a PIX with an IP address if 172.16.64.1
The Linux images have IP addresses in the 192.168.2.0/24 subnet. The PIX
does NAT for
setup. So each guest could have it's OSA addresses be
0F00,0F01,0F02.

Netfilter and iptables are the same thing -- I think. If I remember
correctly, ipchains was installed by default on SLES7. I think Ihad to get
iptables off of the developer CDs. We used SuSEfirewall2 under SLES7 (as
well as SLES8 now) to configure our firewalls/iptables. It's a pretty ok

Not sure if this will help you but Linux (df -h) reports 2.3 gig from a

Thanks for replying so quickly.
Does your card in LCS mode have a non-zero MAC address?
No. It displays a MAC equal to the one that the HMC displays.
Are your routing tables set up to tell the network to route 192.168.x.x

Yes. The Cisco is the gateway with 172.16.64.1 for
Hi Gerard,
This is just off the top of my head, but I think the NFS server that
bundles with z/OS TCP/IP has an interface for exporting VSAM files. So
far I've only used the zOS NFS server to export sequential and PDS datasets
to Linux so I have no real knowledge if the VSAM export works or

Has anyone had any experience combing, or getting the effect of, combining

Something along the lines of EtherChannel would be great but I don't
Hi,
I have a Linux 390 guest machine with all but the /boot partition using
LVM. Everything worked swimmingly until reboot. Now, on reboot, the
system halts with:
VFS: Cannot open root device system/lv_root or 00:00
Please append a correct root= boot option
Kernel panic: VFS: Unable to mount
I think you definitely have a point. I've spent most of the day trying to
figure this one out and, in the words of George Costanza, -- These
pretzels are making me thirsty!
No more root LVM for me.

I'm infatuated with Knoppix Linux. I agree with the person that mentioned

great learning tool if your laptop already has an OS on it that you don't
want to depart with because it runs off of the CD but you can still write
