vgdisplay in SLES 10 SP4 goes into uninterruptable sleep

SUSE Product Topics SLES for System Z
1

Hi,

I am using a critical System z host which cannot be rebooted.
But when I ran vgdisplay in SLES 10 SP4, it went into uninterruptable sleep.
Now I couldnt kill the processes.

Can someone give me suggestions how to kill these process and how to prevent them in future.
I can not reboot the host.

Hi Sathish,

Not sure & also don’t use the real time version myself. I do have some questions:

Have some devices that belonged to one or more volume groups been pulled or paths to it maybe lost? And is this part of a clustered system?

How many VG’s have you configured on this system? And does the lvdisplay command (run against the VG you are trying to list the details of) work normally?

Also curious how you are trying to kill the vgdisplay processes, which commands exactly?
