Has anyone any thoughts (sensible or otherwise) about keeping a penguin
colony up to date with it's software?

Can someone please point me in the right direction. I've installed SUSE
8 under VM 4.3. During the install I used three DASD, a,b, and c. I want
to add another file system on different dasd, format it and add a mount point.
I can't for the life of me find where. I thought YAST would be the spot,
Simple way is to amend the zipl.conf to add the vm address of the minidisk
e.g. parameters='dasd=0999,0300-0303, root=/dev/dasdb1 noinitrd
add your new disk to the end as the order is important.
Then run zipl and reboot.
Cat /proc/dasd/devices to see that it is there and check what
You can even do it dynamically without IPL by
something like
echo add device range=xxx-yyy /proc/dasd/devices
Both scenarios are well documented in Linux for S/390:

Please, please, please. Don't tell people they need to reboot just to add
DASD. That is simply not the case with 2.4 kernels.
echo add device range=addr1-addr2 /proc/dasd/devices
dasdfmt
mke2fs
update /etc/zipl.conf
zipl
Done.
Now, updated the initrd is

commercial products that will help you with this from Linuxcare and BMC. If
not, then things get quite a bit harder.

It does take some planning.
One approach I've used is to set up local APT repositories for different
classes of applications, ie:
local-arch-stable == things that every server should have; security
patches, common applications like system management

One important assumption is that NONE of your servers share any DASD through
VM's read-only minidisk mechanism. This would work well for a penguin colony
that has lots of DASD, but can it work for colonies that are short on DASD
and already sold management on the idea of read-only DASD sharing?
Hi Adam,
Very true - but in my case I needed to dedicate individual NICs to virtual
machines, and also had a PCMCIA device that the virtual machines needed
dedicated access to. Seem like a virtual machine hypervisor needs to
address real hardware access - just like mainframe VM does. Providing

This one was written for SLES7, but should work for SLES8. I gave it again in
Washington DC two months ago, updated for SLES8. I can send you a copy if you want.
Hmmm... if the goal is just to run Linux I would think UML or
alternatives
would be more efficent. VMware is very nice, but if they're
all Linux...
might as well gain back some performance (VMware is resource
expensive).
Keep in mind also that there are 3 generations of VMWare -- the

We are considering consolidating 60+ MQ servers onto zLinux (across 2
IFL's). Does this seem doable?
Are there network considerations with this?
Currently the 60 servers reside on the same raised floor sharing the same
network backbone so I don't forsee any problems but I could be wrong.
thx

Do those 60 MQ Servers do any real work? From our brief stint of testing
with MQ on zLinux it is a resource hog CPU/MEMORY/IO. I don't have any
numbers on performance, but MQ can be rather Computensive especially
when using Persistency. I would have to guess that 2 IFL's may not do
the trick.
I think that the session for WAVV or zEXPO would be a great idea and very
helpful to a great number of people.

I've got to take issue with this, the terminology.
From the definition of virtualization that I know,
As with anything Linux for zSeries, it all depends upon what these
servers are doing. If there is anyway that any of the existing servers
can be measured, then it would be easier to determine if they would be a
good fit for the z.
