ENTRY k / SENSE KEY: yyH

DRIVE FAILURES

This item gives you the two-digit hexadecimal sense key code for the error entry. Every error will have a sense key code. The sense keys report generic categories of error and exception conditions. Initiators typically use sense keys for high-level error recovery procedures.

ENTRY k / ASC: yyH

This item displays the two-digit hexadecimal code for the ASC code that applies to the error entry. (ASC = Additional Sense Code.)

ENTRY k / ASQ: yyH

This item displays the two-digit hexadecimal code for the ASQ code that applies to the error entry. (ASQ = Additional Sense Code Qualifier.)

ENTRY)k$,/85(6LBA 12345678H

This item specifies the Logical Block Address on the drive at which the error occurred, if applicable. (Some errors are not associated with a specific block location on the drive.) The address is an 8-digit hexadecimal number.

This item gives access to the entry for each recorded drive failure occurrence. Records for the last 16 drive failures can be stored in this log. For each failure occurrence, a failure entry number is assigned. The failure entry identifies the drive on which the failure occurred and gives two kinds of SCSI codes that describe the failure. The first is a two-digit hexadecimal ASQ code (Additional Sense Code Qualifier); the second is an eight-digit hexadecimal EXTRA code. ASQ is a standard category of SCSI error codes; EXTRA codes are diagnostic codes unique to Ciprico. The DRIVE FAILURES item relates to SCSI log page number 5.

ENTRY j / ASQ: zzH - This item gives you the two-digit hexadecimal code of the ASQ type that applies to the drive failure occurrence. (ASQ = Additional Sense Code Qualifier.)

ENTRY j / EXTRA: ggggggggH - This item gives you the eight-digit hexadecimal code of the EXTRA type that applies to the error entry.
