Compex Systems Advanced SerialRAID Adapters SA33-3285-02 - Manual (Page 245)

Disk drive errors on SSA subsystems are logged against the physical disk drive (pdisk)
rather than the logical disk drive (hdisk). If you are looking for the cause of a problem
where the failing hdisk is known, you can use either of the following methods to find
that cause:
v Use the Configuration Verification service aid, or give the ssaxlate -l hdisk
command, to determine which pdisks are associated with the hdisk.
v Give the ssa_ela -l hdisk command to run error log analysis. When ssa_ela is run to
an hdisk, it performs an error log analysis for all the devices that support that hdisk.
Those devices are one or more adapters and one or more pdisks.
The following example shows a part of an SSA error log. See the using-system
documentation for a detailed description of all the fields that appear in the error log
display.
LABEL: SSA_LINK_OPEN
IDENTIFIER: 625E6B9A
Date/Time: Tue 23 Sep03:00:00
Sequence Number: 640
Machine Id: 00400076C400
Node Id: identity
Class: H
Type: PERM
Resource Name: ssa0
Resource Class: adapter
Resource Type: ssa
Location: 04-07
The Type field can have the following flags: PEND, PERF, PERM, TEMP, UNKN, and
INFO. These flags are described in the using-system documentation. The PERM flag,
however, is also described here because the SSA definition of the flag is slightly
different from the using-system software definition.
The PERM flag is used to log many SSA errors. The using-system software defines the
PERM flag as an error from which recovery is not possible. For SSA devices, the error,
although possibly permanent, is not necessarily obvious to the customer. The PERM
flag is used here to ensure that when diagnostics are run in Problem Determination
mode, the SSA error log analysis runs, and any problems that need service action are
identified.
Detail Data Formats
The Detail Data fields of SSA error logs use two data formats:
v SCSI Sense Data format
v SSA Error Code format
