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.
