Hi,
First of all you have to do
#vgchange -a n vgname
and reduce the crashed physical volume using # vgreduce VG name PV name(for details pls see the man page)

Then create LVm structures on new disks
#pvcreate /dev/rdsk/cXtXdX
then restore vg config
#vgcfgrestore /dev/vgname pvname

if you have any doubt psl give the output of lvmtab
#strings /etc/lvmtab

Hi,

1)first of all confirm weather it is getting detected in ioscan.
#ioscan -fnC disk
2)check diskinfo showing proper value
#diskinfo /dev/rdsk/cXtXdX
3)if it is a new disk then give pvcreate command
#pvcreate -f /dev/rdsk/cXtXdX
4)then add it in a vg
#vgextend /dev/vgXX /dev/dsk/cXtXdX

Hope this works for u.

Regards,
Rajesh G.

Hi,

I just want to know how did you changed the faulty hard disk ?

best way is like this...
replace the hard disk and set the SCSI id same do device file will be same then do
#pvcreate
and
#vgcfgrestore on that disk

this situation you can move do like this
#mv /etc/lvmtab /etc/lvmtab.0501
#vgscan -v

it will create new lvmtab with appropriate entry.

Hi Mazen,

it's no problem. The physical volume /dev/dsk/c1t2d0 is probably your CDROM drive.

Best regards,

Laszlo
