Recovering from a Disk Drive FailureChapter 12 Solving Problems 1454 Release the latch on the new drive and open its handle. If the handle is closed,you cannot insert the disk drive completely into the bay.5 Insert the new disk drive, making sure you push it forward until it is firmlyseated and the handle begins to swing closed. Then close the handle until it clicksinto place to completely seat the drive to its connection.Note Be sure to push firmly on the drive to securely seat it in the drive bay beforeyou close the handle. You should hear a click to indicate the drive has beeninserted as far as it can go.6 Replace the front bezel (700i Series only).Recovering from a Disk Drive FailureWhen a disk drive fails for any reason, it is represented in AdaptecStorage Manager with a red X, as shown at right.This section explains how to recover when a disk drive fails:• If the pool was protected by a hot spare (see the next section).• If the pool was not protected by a hot spare (see page 145).• If there is a disk drive failure in more than one pool simultaneously (see page 146).• If it is a RAID 0 pool (see page 146).• If multiple disk drives fail within the same pool (see page 146).Failed Disk Drive Protected by a Hot SpareWhen a pool is protected by a hot spare, if a disk drive in that pool fails the hotspare is automatically incorporated into the pool and takes over for the failed drive.For instance, when a disk drive fails in a RAID 5 pool, the pool is automaticallyrebuilt (its data is reconstructed) using the hot spare in place of the failed drive. Youcan’t access the pool until the rebuilding is complete.Note In Adaptec Storage Manager, the color of the hot spare changes from light-blue to dark-blue, showing that it is now part of a pool.To recover from the failure:1 Remove and replace the failed disk drive (following the instructions in “HotSwapping Disk Drives” on page 144).2 Designate a new hot spare to protect the pools on that iSCSI Storage Appliance.
