Physical drives states
Defunct
The physical hard disk drive is defunct.
A drive in the online, hot-spare, or rebuilding state has become defunct. It does
not respond to commands, which means that the ServeRAID controller cannot communicate
properly with the drive.
A hard disk drive in the defunct state
does not necessarily mean that you need to replace the drive. Before you replace
the drive, ensure that:
- All cables are connected correctly
to the backplane and to the hard disk drive. Also, check to ensure that all
cables inside the server are connected correctly.
- The hot-swap drive tray is seated
properly in the drive bay.
Hot spare
A hot-spare drive is a hard disk
drive that is defined for automatic use when a similar drive fails. The drive
capacity of the hot-spare drive must be equal to or greater than the capacity
of the drive being replaced.
Notes: |
- If you want to have a hot-spare
drive or a standby hot-spare drive and also assign RAID level-5 to one
of your logical drives, you must have at least four hard disk drives.
- In the event of a drive
failure in an array that contains only logical drives assigned RAID
level-0, the ServeRAID controller will not activate a hot-spare drive.

Online
The drive is online. It is functioning
properly and is part of an array.
Ready
The ServeRAID controller recognizes
a ready drive as being available for definition.
Rebuilding
The drive is being rebuilt.
Standby
A standby drive is a hard disk drive
that has spun down, CD-ROM, tape, removable media, or enclosure.
