Pvchange

Hi Guy,
I have a question....
I want change IO timeout with pvchange -t, but I have an alternate link, I execute vgreduce to the disk where I execute pvchange, and I see that the primary disk haven't set IO timeout.
Why?

Thanks

Re: Pvchange

This is because the pvchange command works on disk paths not disks. Therefore, you could have a different timeout on your primary path than your alternate path.
Never preceed any demonstration with anything more predictive than "watch this"

Re: Pvchange

Im not sure why you ran the vgreduce. You simply run pvchange -t on each /dev/dsk/cxxx device you want to modify the I/O timeout for.

Have you got the latest pvchange patch ? (for 11i);

PHCO_27408.LVM-RUN: /sbin/pvchange
PHCO_27408.LVM-RUN: /usr/sbin/pvchange

If it doesnt seem to take use pvchange -S to switch from primary to alt then try it, then switch back.
Im from Palmerston North, New Zealand, but somehow ended up in London...
