Chapter 7: Integrated Mirroring and Integrated Mirroring Enhanced
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.
5. [Optional] Select a second hot spare disk.
6. Select S
AVE CHANGES then exit this menu to commit the changes.
The configuration utility pauses while the global hot spares are being added.
Follow these steps to delete a global hot spare:

2. Select DELETE HOT SPARE and then press C.
If there are two hot spares, select which one you want to delete.
3. Select S

7-9 Other Configuration Tasks
This section explains how to perform other configuration and maintenance tasks for
IM and IME volumes.
Viewing Volume Properties
Follow these steps to view the properties of volumes:
1. In the SAS BIOS CU, select an adapter from the ADAPTER LIST. Select the RAID
P
ROPERTIES option.
The properties of the current volume are displayed. If global hot spares are defined,
they are also listed.
2. If two volumes are configured, press A
LT+N to view the other array.
3. To manage the current array, select MANAGE ARRAY and press ENTER.
Synchronizing an Array
The Synchronize Array command forces the firmware to resynchronize the mirrored
disks data in the array. It is seldom necessary to use this command, because the
firmware automatically keeps the mirrored data synchronized during normal
operation. When you use this command, one disk of the array is placed in the
Degraded state until the data on the mirrored disks has been resynchronized.
NOTE: If you create one volume using SAS disks, another volume using SATA
disks, and global hot spare disks, the hot spare disks will only appear when you
view the volume that has the same type of disks as the hot spare disks.
