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 RAIDlevel 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 VolumeA 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 VirtualDisk 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 iscurrently 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 VolumeFollow 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 VolumeIn 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 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.Back to Contents PageNOTE: Activation of migrated RAID volume is only supported when the migrated RAID volume is in an optimal state and contains all the installed harddrives.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, thehard 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 isremoved from a SAS 5/iR controller using the RAID Configuration Utility (regardless of whether the hard drives are present), the RAID volume cannot berestored.NOTE: Proceed to step 3 only if synchronization does not begin automatically.
