Rebuilding RAID 1 Set

This menu selection is used to initiate the copying of data from an

existing drive to a replacement drive that has been installed in a

RAID 1 set after the failure of one of the members.

1. Select ‘Rebuild RAID 1 Set.’

2. Select the desired set and press

Enter.

3. Press ‘Y’ when asked ‘Are You Sure?’

4. The set will be rebuilt. The status of the rebuild is displayed

in the Main Menu window.

Resolving Conflicts

When a RAID set is created, the metadata written to the disk

includes drive connection information including the channel on

the host controller to which it is connected. If there is a drive

failure, and the replacement drive was previously part of a RAID

set or used in another system, it may have conflicting metadata,

specifically in reference to the drive connection information. If

this is the case, this will prohibit the RAID set from being either

created or rebuilt. In order for the RAID set to function properly,

the old metadata must first be overwritten with the new metadata.

To correct this, select ‘Resolve Conflict’ and the correct

metadata, including the correct drive connection information, will

automatically be written to the replacement drive.

1. Select ‘Resolve Conflicts.’

2. Select the ‘Invalid RAID drive’ entry in the Logical Drive

Status window and press

Enter.

3. Follow the prompts to resolve the conflict.

Note that some conflict resolutions may result in the drive letter

assignment changing; for example, the RAID set may have been

drive D: but after the conflict resolution, it may become drive E:.
