Chapter 7 Storage

•Recovering appears when repairing a RAID 1 volume. (A RAID1 volume was once degraded, but you have installed a new disk and the NSA is restoring the RAID1 volume to a healthy state.)

•Degraded when a volume is currently down, but can be fixed. Data access may be slower from a degraded volume, so it’s recommended that you replace the faulty disk and repair the volume as soon as you can.

•Inactive when a disk is missing from a RAID 0 volume or a two-disk JBOD volume. The volume is unusable. If you removed one of the disks you should be able to re-install it and use the volume again (as long as you did not change anything on the disk). If a disk has failed, you need to replace it and re-create the whole volume. All data will be lost. See page 354 for how to install or replace a hard drive.

•Down when a volume is down and can not be fixed.

A down RAID volume cannot be used until you repair or replace the faulty disk(s) in the volume. Degraded means one of the disks in the RAID volume is not available but the volume can still be used. For a degraded volume, you should replace the faulty disk as soon as possible to obtain previous performance. See your Quick Start Guide for more information on replacing a disk.

If it’s down, then the only indication is that you can no longer transfer files to/from the shares in the down volume. If it’s degraded, then file transfer to/from the shares in the degraded volume will be slower.

Note: There is no explicit message from CIFS that tells users their volume is degraded or down.

7.4 Editing a Volume

Click an internal volume’s Edit icon in the Storage screen as shown in Figure 75 on page 161 to open the following screen. Use this screen to change the volume’s name.
