5.5.9 Rebuilding a RAID set The utility displays the condition of the RAID set during the POST. When a RAID set is degraded, you can use the utility to rebuild it. • You may only rebuild Fault Tolerant arrays (RAID 1). • If no spare exists and a hard disk drive fails, you need to create a spare before you can rebuild an array. • By replacing a failed drive of a RAID 1 array with a new drive, you can rebuild to get the array to optimal status and assume fault tolerance. There are two ways to rebuild a RAID set: system shutdown rebuild and manual rebuild. Refer to the sections below for details. System shutdown rebuild When a RAID set drive fails or an array gets degraded, shut down the system and replace the failed drive with a new one (of equal or greater capacity). When you reboot the system, you can assign the new drive as a spare, and automatically start the rebuild process. The existing drive data is copied to the new one, and the original RAID 1 array is recreated. Manual rebuild To manually rebuild a RAID set: 1. Select M a n a g e A r r a y s from the Main Menu, then press to display the list of arrays. 5-64 Chapter 5: RAID configuration
