Hi,

you want to format your OS?

pvcreate -f /dev/rdsk/cXtXdX
or
mediainit -v path

Hi Oprakash,

Do you want to destroy the data on the disk?

# dd if=/dev/zero of=/dev/rdsk/c0t0d0 bs=1024k

mediainit is the tool to low level format the disk which takes long time.

Hi Prakash,

Normally, we do NOT format a disk in Unix.
May be you no longer need the data in that disk/vg.

If this is the case, use:
# vgexport vg_name
and the Vg is gone for ever. Now the disks are free to be used again by making them a part of another vg and overwriting them.

Erase the header info in the disk by:
# pvcreate -f /dev/rdsk/cxtyd0

If you still need to format and erase every single block, use:
# dd if=/dev/zero of=/dev/rdsk/cxtyd0 bs=1024k

Hope this helps.
