Chapter 5
Event Reporting: Templates and Codes
This chapter describes the event codes that the fault management software provides for
spontaneous events and last failure events.
The HSG80 controller uses various codes to report different types of events, and these
codes are presented in template displays. Instance codes are unique codes that identify
events, additional sense code (ASC) and additional sense code qualifier (ASCQ) codes
explain the cause of the events, and last failure codes describe unrecoverable conditions
that might occur with the controller.
Passthrough Device Reset Event Sense
Data Response
Events reported by passthrough devices during host/device operations are conveyed
directly to the host system without intervention or interpretation by the HSG80 controller,
with the exception of device sense data that is truncated to 160 bytes when it exceeds 160
bytes.
Events related to passthrough device recognition, initialization, and SCSI bus
communication events, resulting in a reset of a passthrough device by the HSG80
controller, are reported using standard SCSI Sense Data (see Table 5–1). For all other
events, refer to the templates contained within this section.
■ Instance codes (byte offsets 8–11) are detailed in the “Instance Codes” section on
page 5–20.
■ ASC and ASCQ codes (byte offsets 12 and 13) are detailed in the “ASC/ASCQ
Codes” section on page 5–17.
