3.4 Managing Hot Spares
You can create one global hot spare disk to protect the one or two IM/IME volumes
defined on a SAS controller. Usually, you create the global hot spare at the same time
you create the IM/IME volume. Follow these steps to add a global hot spare disk later
for the existing IM/IME volumes on the controller:
1. On the View Array screen, select
Manage Array
.
2. Select
Manage Hot Spare
on the Manage Array screen, shown in Figure 3.3.
3. Select a disk from the list by pressing the + key, . key, or space bar.
4. After you select the global hot spare disk, press
C
. An error message appears
if the selected disk is not at least as large as the smallest disk used in the IM/
IME volume(s). The global hot spare disk must have 512-byte blocks, it cannot
have removable media, and the disk type must be either SATA with extended
command set support or SAS with SMART support. If SATA disks are used for
the IM/IME volume(s), the hot spare disk must also be a SATA disk. If SAS disks
are used, the hot spare disk must also be a SAS disk. An error message
appears if the selected disk is not the same type as the disks used in the IM/IME
volumes.
