5–46 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
Last Failure Codes and FMU
The format of an Last Failure Code is shown in Table 5–16.
NOTE: Do not confuse the Last Failure Code with that of an Instance Code (shown on
page 5–20). They appear at different byte offsets and convey different information.
Hardware/Software (HW)
The HW flag is located at byte offset 104, bit 7. If this flag is a 1, the unrecoverable
condition is due to a hardware-detected fault. If it is a 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. See Table 5–17 for available
restart codes.
Parameter Count
The Parameter Count is located at byte offset 104, bits 0–3 and indicates the number of
Last Failure Parameters containing supplemental information supplied.
