Hi Ammar,

Use the -f option to force the creation. You will need to be shure there is no valuable data on the disk.

---
-f Force creation of a physical volume (thus deleting any file system present)

use pvcreate -fB instead..

Hi Ammar ,

Try
1.
#pvdisplay -v /dev/dsk/c0t11d0

To know if it is a part of existing vg.

and ,
2.
# strings /etc/lvmtab | grep c0t11d0

Hope then you can go ahead ,

Cheers,
Raj.

Thanks a lot

Ammar ,

You can use -f option with pvcreate to force creation also.

# pvcreate -f /dev/rdsk/c0t11d0
# pvcreate -B /dev/rdsk/c0t11d0

Cheers,
Raj

Hi:

The error indicates that the physical disk was once part of a volume group. Perhaps you vg(import)ed it from another server.

If you truly want to 'pvcreate' it. do:

# pvcreate -B -f /dev/rdsk/c0t11d0

..the '-f' flag forces the operation.

Regards!
