you to import the existing configuration to the RAID controller or clear the configuration so you can create a new configuration using these drives. You can preview the foreign configuration before you decide whether to import it. NOTE: On the SAS 5/iR controller and the SAS 6/iR controller, when a disk set is moved from one controller to another, the disks are reported to SAS RAID Storage Manager as un-configured and good. You can import the existing volume by using the operation to import foreign configurations or you can use the Configuration Wizard to create a new volume on the disks that overwrites any existing data on the disks. To do this, follow these steps: 1 Select a controller icon in the left panel of the Dell SAS RAID Storage Manager screen. 2 Select Operations-> Scan for Foreign Config. If Dell SAS RAID Storage Manager detects any new disk drives, it displays a list of them on the screen. If not, it notifies you that no foreign configuration is found. 3 Follow the instructions on the screen to complete the disk detection. Clearing a Foreign Configuration You can use the controller BIOS configuration utility to clear a foreign configuration. Refer to your SAS controller user's guide for further instructions. This is a non-recoverable operation, so be sure that you want to do this before you continue. Rebuilding a Drive If a single drive in a RAID 1, RAID 5, RAID 6 (PERC 6/i only), or RAID 10 virtual disk fails, the system is protected from data loss. A RAID 6 configuration can survive the failure of two physical drives. The failed drive must be replaced, and the drive's data must be rebuilt on a new drive to restore the system to fault tolerance. (You can choose to rebuild the data on the failed drive if the drive is still operational.) On a Dell SAS 6/iR system, if a RAID 1 virtual disk fails, and if hotspare disks are available, the failed drive is rebuilt automatically without any user intervention. 52 Maintaining and Managing Storage Configurations
