3-43Storage ManagerYou should reboot your operating system to ensure that the hotspare drive is recognized correctly.Hot spares are reserved to automatically replace failed drives inRAID 1 or 10 and RAID 5 or 50 arrays and cannot be accessed bythe operating system for data storage. Hot spares can only protectdrives of equal or less capacity that are attached to the samecontroller as the hot spare.When a drive failure occurs in an array protected by a hot spare,the controller automatically starts rebuilding data onto the hotspare. During this process, Storage Manager swaps the positions ofthe failed drive and the hot spare in the Logical ConfigurationView. The failed drive appears with a red failed flag in the formerposition of the hot spare, and the hot spare appears as a member ofthe array group with a white flag indicating that a rebuildoperation is in process. The array and LSU icons appear withyellow (degraded) flags.When the rebuild is complete, the hot spare icon and flagsdisappear and the drive is displayed as a normal member of thearray. The red flag remains on the failed drive until that drive isreplaced or returned to Optimal status.To replace the failed drive, follow these steps:1 Follow the steps in your hardware documentation to removeand replace the failed drive.2 Click Make Optimal in the new drive’s Information window.The new drive becomes the hot spare, replacing the previoushot spare that is now a member of the rebuilt array group.Note: If you want to try using the drive again, select MakeOptimal without removing the drive. If the operation fails,you should replace the drive.Running a Verify ProcessRunning a manual Verify for a RAID array ensures that theredundant information contained in the array is consistent.
