Rebuilding a Drive
If a drive in a mirrored array (RAID 1 or RAID 1E) fails, MegaRAID Storage Manager software automatically rebuilds the data on a hot spare drive. This is a fully automatic process, so it is not necessary to issue a Rebuild command. You can monitor the progress of drive rebuilds in the Group Show Progress window. To open this window, select Group Operations >> Show Progress.
A red circle to the right of the drive icon
indicates that a drive has failed. A yellow circle appears next to the icon of the virtual drive that uses this drive. This indicates that the virtual drive is in a partially degraded state; the data is still safe, but data could be lost if another drive 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 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 drive icon. Right-click the icon and select Rebuild from the popup menu. A drive rebuild cannot be aborted.
A drive rebuild is also started if you select Make Drive Online from the popup menu.
