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 SAVE 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:

1.Select MANAGE HOT SPARE on the MANAGE ARRAY screen (Figure 7-8).

2.Select DELETE HOT SPARE and then press C.

If there are two hot spares, select which one you want to delete.

3.Select SAVE CHANGES then exit this menu to commit the changes.

The configuration utility pauses while the global hot spare is being removed.

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 PROPERTIES option.

The properties of the current volume are displayed. If global hot spares are defined, they are also listed.

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.

2.If two volumes are configured, press ALT+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.
