Adding a Global Hot Spare
Global hot spares provide an additional level of protection for the data on your disk array.
A global hot spare automatically replaces a failed disk, restoring redundancy and
protecting against a second disk failure. For maximum protection against disk failures it is
recommended that you add a global hot spare for each channel. For more information on
using global hot spares, see
"Global Hot Spares" on page 248
.
A global hot spare is added using an unassigned disk. If there are no unassigned disks
available, you cannot add a global hot spare unless you install a new disk or unbind an
existing LUN.
C
AUTION
If you have disks of different capacities in your disk array, always select
disks of the largest capacity for your global hot spares. This ensures that any
disk failure is protected. See
"Global Hot Spare Disks" on page 61
for more
information on selecting disks for global hot spares.
If a larger disk is used to replace a smaller disk that has failed, the difference
in capacity will be unused. For example, if an 18-Gbyte disk is used as a
global hot spare for a 9-Gbyte disk, the remaining 9 Gbytes of the global hot
spare will be unused.
To add a global hot spare:
1. On the main SAM screen, double-click the Disks and File Systems icon.
2. On the Disks and File Systems screen, double-click the Disk Devices icon. The Disk
Devices list is displayed. There is an entry for each disk array controller.
3. Select a controller for the appropriate disk array from the Disk Devices list.
4. Select the Actions menu, the Disk Array Maintenance menu option, and then Add Hot
Spare. The Add Hot Spare screen is displayed.
