Re: how to check the details of unused disk
Try "vgdisplay -v /dev/vg_name". Is possible looking for specific disk:
--- Physical volumes ---
PV Name /dev/dsk/c0t0d0s2
PV Status available
Total PE 4318
Free PE 350
Autoswitch On

pvdisplay -v /dev/dsk/cxxtxxdxx
Look at the extent map and make sure that no extents are participating in any lvols.

Re: how to check the details of unused disk
A verbose 'vgdisplay' of the volume group will show the physical volumes and the inuse and free extents for each at the end.
# vgdisplay -v vgNN
Thus, if a physical volume shows a Free PE count equal to its Total PE count, it is unused and can be 'vgreduced' from the volume group.
Regards!

Re: how to check the details of unused disk
Hi Praveen,
You may do a #vgdisplay -v to get the Free PE list and find the disks that is not used and you do Xvgreduce to remove those disks from VGs.
Or you can also do a #pvdisplay -v for the disks and find the unused disks.
Regards,
Siva.
