strange to have to provide the VDISK size for each individual virtual

And if you put it in your PROFILE EXEC then as soon as the guest is
autologged the disk is created and the system can then be booted by the

Changing the size isn't an issue for me; I size memory so that we *barely* swap
anyway. I've never has to change the size of a vdisk.

There will be plenty of us reminding you on this post when you found
something happened to the order of your disks in the virtual machine
configuration and the mkswap wiped out your root file system or some
other relevant data...
That shouldn't happen if you are using udev to address them
So, for those of you playing along at home:
I'll eventually release a new VMARC, but I need to find and update the
help file sources first, and I need to do the whole thing under update
control and build the package, and in the meantime:

It's a multi-step process whether you do it at the hypervisor level or inside
the Linux guest, so you're going to need some kind of scripting either way.
The basic Unix philosophy is write

I prefer running SWAPGEN under CMS before starting Linux. If my primary
background were Linux, I might feel differently. Adam's fix to pick up the
disk size from the directory certainly makes things easier
If you put the VDISK in the CP directory entry and use
the REUSE option, SWAPGEN will simply format what's there and write
the signature on the disk.
Well, NOW it will, with the change I just posted.
Hmph. I'd fixed that while back, but guess I didn't commit the fix to the main

Hi All,
We are running SLES10 SP2, and I am trying to switch our vdisk swap from
fba to diag. So far I:
1) run SWAPGEN EXEC with the reuse option (vdisks are defined in the CP
directory)
2) included dasd_diag_mod in the kernel configuration and ran mkinitrd
(verified with lsmod)
3) set the yast
/swapon each vdisk swap
device to use DIAG before you run mkinitrd, zipl, it'd work (I think).

Ray,
When you include dasd_diag_mod in the kernel configuration, did you put
the dasd drivers in the correct order?
Ours is:
INITRD_MODULES=reiserfs dm_mod dasd_diag_mod dasd_eckd_mod dasd_fba_mod
If dasd_fba_mod is first, then the vdisk will always be detected at
bootup as fba.
