Hi,


Present the new disk array to the system.

Then do a vgexport -p -s -v -m .

Keep that mapfile.

Add the new disks to the system. IOSCAN and insf -e that.

Vgcreate and vgimport with the mapfile.

Mount with /Newdisk/

use find with cpio (it you have file size less then 2 GB.) else use tar or cp.

Ensure that your applictions are off with doing so.

Once copied unmount and mount to the old mountpoints...

Dear Sujeet,

execute

#cmquerycl -v

will give you the detailed info about the cluster.
