Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
Last Failure Event Sense Data Response
Unrecoverable conditions detected by either software or hardware and certain
operator-initiated conditions result in the termination of HSZ80 controller operation.
In most cases, following such a termination, the controller will attempt to restart (that
is, reboot) with hardware components and software data structures initialized to the
states necessary to perform normal operations (see Figure 5–2).
