When a RAID volume is synchronized, the firmware synchronizes the data on the secondary hard drive(s) with the data on the primary hard drive of the RAID
level 1 volume. Follow these steps to start synchronization for a RAID level 1 volume:

 

1.

Select Synchronize Virtual Disk.

 

2.

Press Y to start the synchronization or N to cancel it.

 

Activating a RAID Volume

A RAID volume can become inactive if, for example, it is removed from one SAS 5/iR controller or computer and moved to another one. The Activate Virtual
Disk
option allows you to reactivate an inactive RAID volume that has been added to a system. This option is only available when the selected RAID volume is
currently inactive.

 

1.

Select Activate Virtual Disk.

 

2.

Press Y to proceed with the activation or press N to abandon it.
After a pause, the RAID volume will become active.

 

Deleting a RAID Volume

Follow these steps to delete a selected RAID volume:

 

1.

Select Delete Virtual Disk.

 

2.

Press Y to delete the RAID volume or press N to cancel the deletion.
After a pause, the RAID volume will be deleted.

 

Replacing and Rebuilding a Degraded RAID Volume

In the event of a hard drive failure in a RAID level 1 volume, you will need to replace the hard drive and resynchronize the RAID volume.

 

1.

Replace the failed drive with a new drive of the same type and capacity (or larger capacity).

 

2.

Check your management application or the RAID Configuration Utility (Ctrl-C) to ensure synchronization started automatically.

 

3.

Enter the RAID Configuration Utility (Ctrl-C).

 

4.

From the Adapter List screen, select the controller that contains the degraded RAID volume.

 

5.

From the Adapter Properties screen, select RAID Properties.

 

6.

Press <Alt+N> until the degraded RAID level 1 volume is in view, then select Manage Virtual Disk.
The screen shows the RAID volume with a status of "Degraded".

 

7.

Select Add Secondary Disk and select a drive from the list of available drives.
The new hard drive automatically begins synching with the drive of the degraded RAID level 1 volume.

NOTE:

Activation of migrated RAID volume is only supported when the migrated RAID volume is in an optimal state and contains all the installed hard

drives.

NOTICE:

Before deleting a RAID volume, be sure to back up all data on the RAID volume that you want to keep.

NOTICE:

If the hard drives of a RAID volume are removed and the RAID volume's configuration is subsequently deleted from the SAS 5/iR controller, the

hard drives show up only as simple drives with no RAID association if they are placed back onto the same SAS 5/iR controller. Once the RAID volume is
removed from a SAS 5/iR controller using the RAID Configuration Utility (regardless of whether the hard drives are present), the RAID volume cannot be
restored.

NOTE:

Proceed to

step 3

only if synchronization does not begin automatically.
