physical volume not attached

[Hunan_1]

That disk always has belonged to that volume group.
No, I haven't changed anything lately, I guess the disks are SCSI2... how can I know that?
If the i/o cables had moved, I guess all the disk that belong the array would be as NO_HW...
Could be a possibility the disk's path is confused to the OS?
I mean It's been moved. Could I set it online (the disks are hot pluggable)?
Before I didn't have any problem like this.
What are EMC disks?
No I don't have the inq utility, what does the inq utility do?

Hi Hunan,

Do a

vgdisplay -v > /tmp/vg.out 2>&1

vi /tmp/vg.out

This should list the disk that the system is complaining about. If you search with that disk device name in the same file, you will find the corresponding volume group.

This message tells that the VG headers on that disk do not match with VG that it belongs to. Either someone did a "pvcreate -f" on it by mistake or you lost that disk.

Try running ioscan,diskinfo,lssf etc., commands to make sure the disk is physically there. If you confirm that it is there and it is in fact the same disk, then do a vgcfgrestore on it to put back the VG headers.

vgcfgrestore -n vgname /dev/rdsk/cxtydz
vgchange -a y vgname

This should fix your issue if the data on that disk is not already overwritten.
