8.8 Assigning Spare Drive, Rebuild
Settings
Adding Local Spare Drive
A spare drive is a standby drive automatically initiated by controller
firmware to replace and rebuild a failed drive. A spare drive must
have an equal or larger capacity than member drives. A local spare
should have a capacity equal or larger than the members of the logical
drive it is assigned to. A global spare should have a capacity equal or
larger than all physical drives used in an array.
Choose “View and Edit SCSI Drives” on the main menu, press
[ENTER]. Move the cursor bar to a SCSI drive that is not assigned to a
logical drive or as a spare drive (usually indicated as a "New Drive"),
and then press [ENTER].
Choose “Add Local Spare Drive” and press [ENTER]. A list of
available logical drives will be displayed on the screen.
Move the cursor bar to a logical drive, then press [ENTER]. The
unassigned SCSI drive will be assigned to this logical drive as the
Local Spare Drive.
When prompted to “Add Local Spare Drive?”, choose Yes to confirm.
Adding a Global Spare Drive
A global spare replaces and is used to rebuild any failed drive in any
of the logical drives of a RAID array.
