Hi,

Thanks for the immediate respose.But I am not able find the following doc KBAN00000347 and the link provided in the mail.I have one doubt. For recovering the mrror root, first we have to reduce the mirror and then again we have to follow the same steps ......?, please clarify me...

Thanks

No need to reduce first the mirror, just to restore vg information on the new disk, reactivate vg00, and resynchronise the stale partition...

sorry....
You need to prepare the new disk first:
# pvcreate -f /dev/rdsk/cxtxdx
# vgcfgrestore -n /dev/vgXX /dev/rdsk/cxtxdx
# vgchange -a y /dev/vgXX
# vgsync /dev/vgxx
# mkboot /dev/rdsk/cxtxdx
# mkboot -a "hpux -lq" /dev/rdsk/cxtxdx
# shutdown -yr 0
