Rebuilding a Drive

If a physical disk in a mirrored array (RAID 1 or RAID 1E) fails, MegaRAID Storage Manager software automatically rebuilds the data on a hot spare disk. This is a fully automatic process, so it is not necessary to issue a Rebuild command. You can monitor the progress of disk rebuilds in the Group Show Progress window. To open this window, select Group Operations >> Show Progress.

You can tell that a disk drive has failed if a red circle appears to the right of the disk icon: . A small yellow circle also appears by the icon of the virtual disk that uses this physical disk: . This means that the virtual disk is in a degraded state; the data is still safe, but data could be lost if another disk fails.

When the new drive spins up, the drive icon changes to green as the rebuild begins, and an up-arrow appears above the drive icon.

If you want to force a disk drive into Fail status in order to trigger a rebuild, right-click the drive icon, and select Make Drive Offline. A red circle appears next to the disk icon. Right-click the icon and select Rebuild from the popup menu. A disk rebuild cannot be aborted.

A disk rebuild is also started if you select Make Drive Online from the popup menu.
