Solution 2189960.1 : Firmware upgrade with existing faults from prior ILOM rev 3.2.6 to after results in misclassified Subsystem on T4-x, T5-x, & T7-x

Applies to:

SPARC T4-1 - Version Not Applicable and later
Netra SPARC T4-2 Server - Version Not Applicable and later
Netra SPARC T4-1 Server - Version Not Applicable and later
Netra SPARC T4-1B - Version Not Applicable and later
SPARC T4-2 - Version Not Applicable and later
Information in this document applies to any platform.

Symptoms

After FW upgrade from ILOM revision prior 3.2.6 to after, existing faults can get a misclassified Subsystem. The system log also shows this misclassification of a PSU fault in file: ilom/@usr@local@bin@spshexec_show_-script_@System@Log@list.out as follows:

-> show -script /System/Log/list

The BUI will also misclassify the faulted subsystem on the Summary tab.

This affects systems: T7-x, T5-x, or T4-x when upgraded from a revision prior 9.7.0.a, 9.6.5.a, 8.9.5.a (respectively) to later.

Cause

This problem occurred after an additional sub-system was added in ILOM version 3.2.6. Misclassifications for pre-existing fault's sub-system after the upgrade:

This problem results due to the resolution of bug 22264577 - "Put Cartridges under /System in SDM hierarchy". In ILOM 3.2.6, the HDL_SUB_SYSTEMS was modified to add the Cartridges category in the middle of the table. Faults detected prior the firmware upgrade will get classified with the old subsystem number on the upgraded system.

#define HDL_SUB_SYSTEMS \
HSS_T(SUB_SYSTEM_UNKNOWN, "Unknown") \
HSS_T(SUB_SYSTEM_NONE, "System") \

Solution

This problem can be corrected by clearing the fault & allow the firmware to re-identify the fault if it remains.

It is highly recommended to repair all faults & to reset the ILOM prior performing a firmware upgrade.
