Hi Masood,
Detach the deffective disk
swlist | grep OLR
pvchange -a N pvname
Remove the disk
Attach new disk
ioscan -fnC disk -->find the new disk
cat < /tmp/partitionfile
> 3
> EFI 500MB
> HPUX 100%
> HPSP 400MB
> EOF
Create the EFI partitions using this template.
idisk -wf /tmp/partitionfile pvname
insf -eC disk
format the efi partision #1
efi_fsinit -d /dev/rdsk/cxtxdxs1
mkboot -e -l /dev/rdsk/c1t4d0
echo "boot vmunix -lq" > /tmp/auto.lq
efi_cp -d /dev/rdsk/cxtxdxs1 /tmp/auto.lq /EFI/HPUX/AUTO
Now you van restore the LVM information to the new disk
vgcfgrestore -n vg00 /dev/rdsk/cxtxdxs2
pvchange -a y /dev/dsk/cxtxdxs2
Wait couple of minuts all the lv's to sync.
(If the disk is not accessible by lvm but an entry in lvmtab, then need to remove the disk entries using pvkey after that remove the ghost disk from vg00)
