Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
NOTE: Do not confuse the Last Failure Code with the Instance Code (see page
5–20). They appear at different byte offsets and convey different information.
HW
This hardware/software flag is located at byte offset 104, bit 7. If this flag is equal to
1, the unrecoverable condition is due to a hardware-detected fault. If this flag is equal
to 0, the unrecoverable condition is due to an inconsistency with the software, or an
intentional restart or shutdown of the controller was requested.
Restart Code
Located at byte offset 104, bits 4-6, the Restart Code describes the actions taken to
restart the controller after the unrecoverable condition was detected. Table 5–2 gives a
description of restart codes and their descriptions.
Parameter Count
The Parameter Count, located at byte offset 104, bits 0-3, indicates the number of Last
Failure Parameters containing supplemental information supplied.
