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.
