Hi all,
I'm having problems logging on to my SLES 10 system.
I originally had this system running as a LPAR some months ago, before
installing VM.
I have now defined a VM Guest (LINUX00), attached the DASD I had for the
LPAR to the guest, and successfully IPL'd SLES 10.
On the Linux guest
If you are unable to put on the VM APAR, there is a way to work around
it in Linux. See my old post at

Thanks. Do you also know where to find this type of info.
There are two options, vmhalt and vmpoff.
It works, if you specify
vmpoff=LOGOFF
and use
"halt -p" or "poweroff"
If you specify
vmhalt=LOGOFF
and use
"halt"
it will work as well.
you can specify both, the vmpoff and vmhalt option.

He will need "-t nfs" to tell the mount that the filesystem type is

it finds one. Does it?
