Controller drive port (host) events

CC to Host ID:

QL:

This indicates that an
unrecoverable drive error
has occurred for a particular
command. This may be due
to a drive error in a non fault
tolerant mode, such as RAID
0, or when the array is
already in a degraded mode.
The controller will pass the
status from the drive back to
the host system, to allow the
host recovery mechanisms
to be used. The meaning of
each field is as follows:

ID: Host ID

LUN: LUN requested

P: Host port number

OP: SCSI command code

SN: SCSI sense key

EXT: SCSI extended sense
key

QL: SCSI extended sense
key qualifier

Data is not
recoverable.

Backup all data,
and restore to a
new array.
