2102 Array Additional Sense Codes And Qualifiers (ASC/ASQ)
Many of the ASC/ASCQ code are identical to the ones used in normal disk drives.
This section lists the Additional Sense Codes (ASC), and Additional Sense Code
Qualifier (ASCQ) values returned by the array controller in the sense data. SCSI-2
defined codes are used when possible. Array specific error codes are used when
necessary, and are assigned SCSI-2 vendor unique codes 80-FFH. More detailed
sense key information may be obtained from the array controller command
descriptions or the SCSI-2 standard.
Codes defined by SCSI-2 and the array vendor specific codes are shown below.
The most probable sense keys (listed below for reference) returned for each error
are also listed in the table. A sense key encapsulated by parentheses in the table is
an indication that the sense key is determined by the value in byte 0x0A of the
User- configured region of the NVSRAM.

If a controller card was recently replaced, the cache batteries may
not have been fully charged. It can take two days for the cache
batteries to be fully recharged. During this time, errors will be logged
in the error log. Do not replace the controller.

A controller has changed world wide names (most likely either it was
replaced without placing it in reset first, or cabling was changed so
that a different controller with the same SCSI ID is on the loop).

Logical Unit Is In Process Of Becoming Ready
The controller is executing its initialization functions on the addressed logical unit. This
includes drive spin-up and validation of the drive/logical unit configuration information.
