To start a synchronization, select Synchronize Array on the Manage Array screen and then press the Y key. (To cancel a synchronization, press the N key.) Activating an array An array becomes inactive if, for example, it is removed from one controller or computer and moved to another one. The Activate Array option enables you to reactivate an inactive array that has been added to a system. This option is only available when the selected array is currently inactive. To activate an array, select Activate Array on the Manage Array screen and then press the Y key. (To cancel the activation, press the N key.) After a pause, the array becomes active. Deleting an array CAUTION: If the array contains any data that you want to keep, back up the data before deleting the array. To delete an array, select Delete Array on the manage Array screen, and then press the Y key. (To cancel the deletion, press the N key.) After a pause, the firmware deletes the array. NOTE: When an array has been deleted, you cannot recover it. When a RAID 1 array is deleted, the data is preserved on the primary disk. The master boot records of other disks in the array are deleted. For other RAID types, the master boot records of all disks are deleted. Locating a disk drive There are two ways to physically locate a disk drive: • On the Create New Array screen, the locator LED on the drive glows when you select a drive to be part of a RAID array. When the RAID array is created, or if you deselect the drive from the array, the locator LED is extinguished. • On the SAS Topology screen, move the cursor to the drive and press the Enter key. The locator LED on the drive remains lit until you press another key. Selecting a boot disk 1. Open the configuration utility. 2. On the Adapter List screen, select an adapter. 3. On the Adapter Properties screen, select SAS Topology. The SAS Topology screen opens. If selection of a boot device is supported, the Alt+B option is listed at the bottom of the screen. If a device is currently configured as the boot device, the Device Info column displays the word Boot. • To remove the boot disk designator, move the cursor to the current boot disk and press the Alt+B key combination. The adapter no longer has a designated boot device. • To select a boot disk, move the cursor to the disk and press the Alt+B key combination. The selected disk moves to scan ID 0 on the next boot and remains at this position. There can be only one boot disk. Moving arrays When you remove an array and install it into another system (or reinstall it into the same system), the array is initially inactive and must be reactivated. To reactivate an array, follow the procedure described in "Activating an array" on page 18. If the moved or reinstalled volume is the boot volume, you will see a non-system disk message and the system will not boot. To enable the system to boot, restart the system and then press the F8 key when prompted during system initialization. When the BIOS configuration utility opens, activate the array as described previously and then restart the system. You can have only one hot spare per adapter. If you install a RAID 1 array with a hot spare into an adapter that already has an active RAID 1 array and a hot spare, the SAS Topology screen of the BIOS configuration utility reports the hot spare in the added array as Not Responding. In this case, after you have activated the added RAID 1 array, restart the system and then open the BIOS configuration utility and delete the second hot spare. The SAS Topology screen then reports the drive as Responding. SAS BIOS configuration utility 18
