7.7.4 Disk Replacement and Volume Labels
When you create a volume, the NSA writes the volume label to the disk.
"
Deleting a volume removes volume label information on its disk(s).
It is
recommended that you first delete a volume before removing its disk(s).
If you remove a disk(s) without deleting its volume and you later put the disk(s) back in a
different volume, problems may occur. For example, suppose you have two disks, Disk A and
Disk B and you create two JBOD volumes, volume1 (with Disk A) and volume2 (Disk B).
Later you remove Disk A and replace it with another disk, Disk C and you re-create volume1.
(You did not delete volume1 when you removed Disk A.) Later you replace Disk B with Disk
A. Disk A still retains the volume1 label, so at this point there are conflicting duplicate
volumes since both Disk A and Disk C have the volume1 label.
