NOTE: The order of the controllers displayed on Storage Management may differ from the order of the controllers

displayed in the Human Interface (HII) and PERC Option ROM. The order of the controllers does not cause any

limitation.

NOTE: When creating virtual disks using software RAID controllers, the information related to the physical disks linked

to the virtual disk is enumerated or displayed on Storage Management after a short delay. This delay in displaying the

information does not cause any functional limitation. If you are creating partial virtual disks, Dell recommends that you

provide Storage Management adequate time between each partial virtual disk creation process.

NOTE: RAID 10 virtual disk reconfiguration operation is not supported with Intelligent Mirroring.

Replacing physical disks in RAID1 configuration

About this task

Perform the following steps to replace physical disks in RAID1 configuration:

Steps

1. In the Virtual Disk Management window, select Virtual Disk # and press the down-arrow key until Physical Disks are highlighted.

2. Press the right-arrow key to expand the list of physical disks that are members of the virtual disk.

3. Press the down-arrow key and highlight the desired physical disk you want to replace. Press <F2> to expand the list of allowed

operations on the disk.

4. Select Replace.

5. Select Start.

6. Press the down-arrow to highlight a replacement disk and then press the spacebar to select the disk.

7. Select OK to start the replacement.

NOTE:

The replacement disk must be a hot spare or an unconfigured disk without a foreign configuration. It must

have the same or greater capacity and should be of the same type as the disk it is replacing.

NOTE: Each physical disk in the RAID1 configuration should be replaced one by one.

Thumb rules for RAID configuration

The following are the thumb rules for RAID configuration:

• Both drives should be of same size.
