Hi,

looks like problem with /etc/lvmtab file

#mv /etc/lvmtab /etc/lvmtab.old
#vgscan -a -v
#vgcfgbackup

let's know the result

Does the disk show up in your ioscan as 'CLAIMED' ?

What does 'vgdisplay -v /dev/myvg' report?
(change this to your volume group name)

I would not run a 'vgscan' until this is resolved.

chances are that your lvmtab is corrupt.

try regenerating the lvmtab wioth vgscan after taking a backup of the lvmtab.

the disk still "CLAIMED" in my system ,and i already do a vgscan , after do that, the reply of vgcfgbackup still as before

Please post these results:

# diskinfo /dev/rdsk/c1t2d3

and if it is part of a volume group already (I am assuming it is)

# pvdisplay /dev/dsk/c1t2d0

Hi,
apart from Michael suggestion also post the o/p

#dd if=/dev/dsk/c1t2d3 of=/dev/null bs=1024k

check for any I/O errors
