Users Guide

Use the Unmirror task to separate mirrored data and restore one half of the mirror to free space. Unmirroring a RAID 1 or RAID 1-
concatenated virtual disk results in a single, nonredundant concatenated virtual disk. Unmirroring a RAID 10 virtual disk results in a single,
nonredundant RAID 0 (striped) virtual disk. Data is not lost during this operation.
NOTE: On systems running Linux operating systems, an Unmirror cannot be performed on a mounted virtual disk.
To Unmirror
Click Unmirror. To exit without unmirroring, click Go Back To Virtual Disk Page.
CAUTION: Your virtual disk is longer redundant.
To Locate Unmirror In Storage Management
1 In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2 Expand a controller object.
3 Select the Virtual Disks object.
4 Select Unmirror from the Available Tasks drop-down menu.
5 Click Execute.
Assigning And Unassigning Dedicated Hot Spare
Does my controller support this feature? See Supported Features.
A dedicated hot spare is an unused backup disk that is assigned to a single virtual disk. When a physical disk in the virtual disk fails, the hot
spare is activated to replace the failed physical disk without interrupting the system or requiring your intervention.
For more information on hot spares including size requirements, see Protecting Your Virtual Disk With A Hot Spare. For considerations
regarding RAID 10 and RAID 50 virtual disks created using the controller BIOS.
Assigning A Dedicated Hot Spare
1 Select the disk in the Connector (channel or port) table that you want to use as the dedicated hot spare. On some controllers, more
than one disk can be selected. The disks you have selected as dedicated hot spares are displayed in the Disks currently congured as
dedicated hot spare table.
2 Click Apply Changes when ready.
