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.
