SCSI ASC/ASCQ Table Format Explanation

The following shows several examples of table entries for ASC/ASCQ values with each column of the table identified in detail.

|-> ASC value (in hexadecimal)

|| |-> ASCQ value (in hexadecimal)

|| ||  |-> Codes identifying devices that may use the ASC/ASCQ pair
|| ||  |-> value.  (See list of device code letters below.)
|| ||  |
|| ||  |            |  |-> Error or exception indicated by the
|| ||  |            |  |-> ASC/ASCQ pair value.

An ASC/ASCQ code value may be used by several SCSI device types. The letters in the DTLPWROMAEBKVF column indicate which SCSI device types have the option of using the listed ASC/ASCQ value. When all the DTLPWROMAEBKVF letters are present, then all SCSI device types may use the listed ASC/ASCQ value. If only one letter is present (such as with the PAPER JAM ASC/ASCQ in the example above) then only one SCSI device type may use the listed ASC/ASCQ. (In the case of the PAPER JAM example, the only SCSI device type that may use the ASC/ASCQ is the Printer Device type.)

The complete list of letters and the SCSI device types they represent is as follows:
