10.2.4 Assign Global Hot Spare
This function registers a drive as a Global Hot Spare.
A Global Hot Spare is a spare drive (hot spare) that is registered in the RAID group instead of the failed drive
when a drive failure is occur. A Global Hot Spare, unlike a Dedicated Hot Spare, can be used by all of the RAID
groups.
If a drive fails, data copy (rebuild) to a Global Hot Spare starts automatically.
When a failed drive is replaced, the data is copied back from the Global Hot Spare that is substituting for the
failed drive, and the Global Hot Spare then returns to a spare drive.
• Drives that are currently used cannot be registered as Global Hot Spares.
• Make sure to register a Global Hot Spare with the same or a larger capacity than the data drives. If the
Global Hot Spare capacity is smaller than the data drive, the drive does not work as the hot spare.
• When a mix of SAS disks, Nearline SAS disks, SSDs, and SEDs are installed together in the ETERNUS DX
Disk storage system, Global Hot Spare of each type is required. Register the Global Hot Spare with the
same capacity as the maximum capacity drive for each type.
• To use hot spares on a priority basis, make sure to register the Dedicated Hot Spare for a RAID group that
contains important data. Refer to "10.2.6 Assign Dedicated Hot Spare" (page 704)
for details.
• If the Dedicated Hot Spare is registered for a RAID group to which a failed drive belongs, the Dedicated
Hot Spare is used before the Global Hot Spare. If there is no unused Dedicated Hot Spare and the drive
fails, the Global Hot Spare is used.
• Depending on the hot spare usage status, a drive with a different capacity and type from the failed drive
may be used.
• Hot Spares can be registered any slots of the CEs (only for the ETERNUS DX80 S2/DX90 S2) and the DEs.
