Rebuild a degraded RAID Array on a SATA or SAS RAID

Postby hr-ethadmin » Sat Jun 01, 2013 10:46 am

When an array is protected by a hot spare, if a disk drive in that array fails the hot spare is automatically incorporated into the array and takes over for the failed drive. When a array is not protected by a hot spare, if a disk drive in that array fails, remove and replace the failed disk drive. The controller detects the new disk drive and begins to rebuild the array.

For the event that the above does not apply, or to start a rebuild of a RAID array manually, there are three possible ways to do this.

Manual Rebuild using ACU (Array Configuration Utility) BIOS

Replace the failed drive with a new one (of equal or greater capacity). Boot the system, press CTRL + A to access the ACU utility on system boot up. When inside the ACU utility, select 'Array Configuration Utility', then press Enter. Select 'Initialize Drives' and initialize the new drive that you have added to the system.
Then select 'Manage Arrays'. Highlight the array that needs to be rebuilt, and select CTRL + S option in order to manage hot spares for the array, add in the new drive as global hot spare for the array and a rebuild will begin on the degraded array automatically.
