Synchronizing a RAID Volume (Virtual Disk) 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 6/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. 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. Deleting a RAID Volume NOTICE: Before deleting a RAID volume, be sure to back up all data on the RAID volume that you want to keep. 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. NOTICE: If the hard drives of a RAID volume are removed and the RAID volume's configuration is subsequently deleted from the SAS 6/iR controller, the hard drives show up only as simple drives with no RAID association if they are placed back onto the same SAS 6/iR controller. Once the RAID volume is removed from a SAS 6/iR controller using the RAID Configuration Utility (regardless of whether the hard drives are present), the RAID volume cannot be restored. 48 Advanced Features
