Physical drives states


Defunct drive 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:

  1. 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.

  2. The hot-swap drive tray is seated properly in the drive bay.

Hot Spare drive 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:
  1. 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.

  2. 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 drive Online

The drive is online. It is functioning properly and is part of an array.


Ready drive Ready

The ServeRAID controller recognizes a ready drive as being available for definition.


Rebuilding drive Rebuilding

The drive is being rebuilt.


Standby Hot-Spare drive CD-ROM drive Tape drive Enclosure Standby

A standby drive is a hard disk drive that has spun down, CD-ROM, tape, removable media, or enclosure.
