Operating Systems HP-UX Converting RAW Disks to Filesystem Post 302636777 by Peasant on Tuesday 8th of May 2012 02:29:27 AM

If it's one physical disk, then your options are limited.

You can do pvcreate on it, put it into LVM and make a logical volume then filesystem sized 1.2 TB, mount and export it via NFS.

Remaning space will be left in your volume group.
You will be able to create additional logical volumes, but you won't be able to use rest for other purpose.

After you are finished, you will do vgremove of that volume group and then pvremove of that disk to return to initial state.
