Failed
This shows you a physical disk that was configured as online or hotspare but
failed, but the controller firmware detected an unrecoverable error and marked
this disk as failed.
Tip: After a physical disk failed you should check the events at this disk. We
recommend to replace a failed disk. However after you have a valid backup for
any data you want to keep, you can try to rebuild this disk. If it failed or a
critical event is logged against this disk, replace it.
Missing
A missing drive is a physical drive that is removed or marked missing from an
enclosure and is a member of a configured virtual disk.
Tip: If the drive state is Missing but the drive is physically present, try
reseating it and seeing if that changes the state back to Unconfigured Good.
A physical disk previously forced to offline can be marked as missing also. See
"Offline" on page 177.
