If SD/6000 is installed on the system, it runs error log analysis whenever a hardware
error is logged, and raises an incident if problems are found that need service activity.
Detailed Description
Error log analysis determines whether the data that is in the error log indicates that
service activity is needed on the subsystem. The analysis uses the detailed data that is
logged with each error.If service activity is needed, an SRN is produced. This SRN
provides an entry point into the maintenance procedures that are given either in this
book or in the Service Guide for the SSAsubsystem. (See “Service Request Numbers
(SRNs)”on page411 for more information about SRNs.)
Error log analysis can be started in several ways:
vIf you run diagnostics in Problem Determination mode to an SSAdevice, one of the
following procedures occurs:
–An error log analysis is performed for all SSAdevices if any SSA device has a
permanent (PERM) error in the error log.
–An error log analysis is performed for that device before the physical device is
tested. If errors are found, no test is performed on the hardware.
vError log analysis is performed every 24 hours by the run_ssa_ela cron (see
“run_ssa_ela cron”on page 232).
vYoucan use the diag command to run error log analysis. On the command line,
enter:
diag -ecd [device]
Error log analysis runs for the selected device. If the analysis determines that service
action is needed, a message is displayed. This message indicates that a problem
was detected, and requests that diagnostics be run to that device.
vYoucan run error log analysis to all SSA devices. On the command line, enter:
ssa_ela
Alist of SRNs for all SSA devices that need service action is displayed.
vYoucan run error log analysis for selected SSA devices. On the command line,
enter:
ssa_ela [device]
The device that is selected can be an SSAadapter, a pdisk, or an hdisk. If an hdisk
is selected, the error log analysis runs for the adapters that control the selected hdisk
and the pdisk (or pdisks if it is a RAID array) that makes up the hdisk.
vIf SD/6000 is installed on the using system, and a hardware error is logged, the
SD/6000 runs error log analysis and reports an incident if problems are found that
need service activity.
Error Log Analysis Routine
The purpose of the SSAerror log analysis routine that is contained in the diagnostics is
to generate an SRN for any logged errors that need service action. Normally,the
error-log-analysis is related to the previous 24-hour period. If you want to perform an
