Chapter 6 Storage Screens

NSA-220 User’s Guide

If you do not want to keep the data on a disk that you will remove, it is recommended that you

delete the volume before you remove the disk. If you remove a disk(s) without deleting its

volume and you later put the disk(s) back in a different volume, you may have more than one

volume with the same name. 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 both Disk A and Disk C have the volume1 label.

Although you can still use the volumes, you may find the naming confusing.
