For hard disk being set up as a RAID drive the text “RAID disk” may show up in the Usage field or the
“Free disk” message is display instead. See Figure3.5.2.1 for illustration.
You may click buttons below the slot numbers to give instructions to individual hard disk. The Status
and Usage fields display related information afterwards (see Figure3.5.2.2).
1. Set Free Disk
This function can be used only for disks that have been set to certain RAID level. The RAID that
contains the released disk will downgrade automatically. If you have chosen Global / Dedicated
spare function the Rebuilding operation will be initiated automatically.
2. Set Global Spare
You may set up hard disks at status of Free disk to be a Global spare one. If one of the disk drives in
the RAID fails the RAID system will be rebuilt with the Global spare disk.
3. Set Dedicated Spare
You may set up hard disks at status of Free disk to be a Dedicated spare one for specific RAID level.
If one of the disk drives in the RAID fails the RAID system will be rebuilt with the Dedicated spare
disk at top priority.
4. Upgrade
This function upgrades the firmware of hard disks directly. For disks in the process of rebuilding or
other operations the upgrade process takes place only after the in-process operations are
completed. (This function supports the WD and Seagate drives now.)
5. Turn on the Indication LED
You may use function to identify the actual location of failed hard disks if the existing LED indicator
light fails to do so.
6. More Information
This function assists you to get more details about individual hard disks as shown in Figure3.5.2.3.
