Re: PV Status Unavailable
I would do a "diskinfo" and a check with "dd", if successful, activate the VG again.
Hope this helps!
Regards
Torsten.

Re: PV Status Unavailable
Try:
# dd if=/dev/rdsk/c4t2d0 of=/dev/null bs=8192k count=10
dd should not show any error.
Check /var/adm/syslog/syslog.log about c4t2d0 disk.
Regards.

Re: PV Status Unavailable
Thanks everybody for your quick response.
Actually I have identified the root cause and it is like this,
the said disks were allocated by the storage administrator in two nodes by mistake, so when created vg01 in one node and then created vg01 in another node using the same physical disk, the earlier node's vg01 got corrupted and in the vg01 of first node the status of the PV was showing unavailable.
Thanks again.
