Logical drive status values are as follows:

Okay (OKY)
– The volume is active and drives are functioning properly. User data
is protected if the current RAID level provides data protection.

Degraded (DGD)
– The volume is active. User data is not fully protected because
the configuration has changed or a drive has failed.

Failed (FLD)
– The volume has failed.

Missing (MIS)
– The volume is missing.

Initializing (INIT)
– The volume is initializing.

Online (ONL)
– The volume is online.
Physical device status values are as follows:

Online (ONL)
– The drive is operational and is part of a logical drive.

Hot Spare (HSP)
– The drive is a hot spare that is available to replace a failed
drive in an array.

Ready (RDY)
– The drive is ready for use as a normal disk drive, or it is ready to be
assigned to a disk array or a hot spare pool.

Available (AVL)
– The drive may or may not be ready, and it is not suitable for
use in an array or a hot spare pool.

Failed (FLD)
– The drive failed and is now offline.

Missing (MIS)
– The drive has been removed or is not responding.

Standby (SBY)
– The device is not a hard-disk device.

A.3.5 HOTSPARE Command
The HOTSPARE command adds a hot spare drive to spare pool 0 or deletes a hot spare
drive. The capacity of the hot spare drive must be greater than or equal to the capacity
of the smallest drive in the RAID volume. You can verify this by using the DISPLAY
command on the drive.
