Solution 2190976.1 : Wrong "Subsystem" reported in the BUI and "show /System/Log/List" after upgrading from 9.5.x (or earlier) to 9.6.x (or later)

Applies to:

SPARC M6-32 - Version All Versions to All Versions [Release All Releases]
SPARC M7-8 - Version All Versions to All Versions [Release All Releases]
SPARC M7-16 - Version All Versions to All Versions [Release All Releases]
SPARC M5-32 - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Symptoms

After a firmware upgrade from SysFW 9.5.x (or earlier) to 9.6.x (or later), existing faults can get a misclassified Subsystem.

For instance, the System Log shows the misclassification of a PSU as follows:

-> show -script /System/Log/List

Log
ID Date/Time Event Type Subsystem

277 Sun Sep 18 02:33:54 2016 Power Supply Service Required Memory

A Power Supply has failed and is not providing power to the server.

The BUI will also misclassify the faulted subsystem.

Changes

Upgrade from 9.5.x (or earlier) to 9.6.x (or later) for M5/M6-32

Upgrade from 9.5.x (or earlier) to 9.7.x (or later) for M7 (there is no SysFW 9.6.x for M7)

Cause

A new Subsystem category has been added to the list of Subsystem values in SysFW 9.6.x (or later). This has caused a shift in the ID number associated to some "Subsystem"

Subsystem ID#	SysFW 9.5.x (or earlier)	SysFW 9.6.x (or later)
1	Unknown	Unknown
2	System	System
3	CPU Module	CPU Module
4	Domain Configuration Unit	Cartridge
5	Processors	Domain Configuration Unit
6	Memory	Processors
7	Power	Memory
8	Cooling	Power
9	Storage	Cooling
10	Networking	Storage
11	I/O Modules	Networking
12	PCI Devices	I/O Modules
13	Firmware	PCI Devices
14	Blade	Firmware
15	Servers	Blade
16	Other Removable Devices	Servers
17		Other Removable Devices

Based on the above table, one can easily see that a "Power" issue on a system running 9.5.x (or earlier) has a Subsystem ID number equal to 7.

When running SysFW 9.6.x (or later), Subsystem ID number 7 is "Memory"; hence a "Power" issue that occurred while system was running 9.5.x (or later) will be reported as a "Memory" issue after upgrading to 9.6.x (or later).

When running SysFW 9.6.x (or later), an error that occurred prior to the upgrade to SysFW 9.6.x (or later) with the Subsystem listed in the first column should be interpreted as the corresponding Subsystem listed in the second column.
Memory	Power
Power	Cooling
Cooling	Storage
Storage	Networking
Networking	I/O Modules
I/O Modules	PCI Devices
PCI Devices	Firmware
Firmware	Blade
Blade	Servers
Servers	Other Removable Devices

New errors occurring after the upgrade to SysFW 9.6.x (or later) will have the correct Subsystem value (and should not be re-interpreted according to the above table).

see Bug 24703066 - "show /System/Log/List" is reporting the wrong "Subsystem"

Solution

Fix all hardware errors prior to upgrading to SysFW 9.6.x (or later) to avoid the a BUI status page with misclassified faults.
Interpret the Subsystem of old errors [errors that occurred prior to upgrade to 9.6.x (or later) ] using the above table.
