Description

Service processor System Firmware may need to be upgraded when replacing a faulty fan module.

Oracle has incorporated a new controller chip into recently manufactured fan modules. Sun System Firmware 9.1.1.b has been augmented with support for the new fan modules, and the firmware upgrade is required to properly utilize Field Replaceable Units (FRUs).  Domains must be stopped and restarted after upgrading the system firmware, which might be disruptive to system operation during fault maintenance. Advance notification is being provided to allow customers to plan system firmware upgrades in regular maintenance schedules. Upgrading the system firmware prior to any need for fan module replacement will avert unplanned domain interruption.

Occurrence

This issue can occur on the following platforms:

• SPARC M5-32 Servers with Firmware version 9.1.1.a or lower
• SPARC M6-32 Servers with Firmware version 9.1.1.a or lower

Note: No other platforms are affected by this issue.

To determine the current firmware version on one of these servers, do the following:

   -> show /HOST0 sysfw_version

    /HOST0
     Properties:
     sysfw_version = Sun System Firmware 9.1.1.a

Symptoms

If the described issue occurs, fan module FRUs may improperly be faulted upon installation. A FMA 'fmadm faulty' message on the service processor will list a fault similar to the following:

    2014-02-01/19:50:02     /SYS/FM16 fault.chassis.device.fail
    Fault  SUNW-MSG-ID: SPT-8000-1Q  UUID:

To match BugID 18169500, the FMA MSG-ID of SPT-8000-1Q must be diagnosed for a fan module (FM).

Workaround

This issue is addressed in the following firmware releases:

• Sun System Firmware version 9.1.1.b or later (as delivered in patch 18189994 or later)

For the latest information on Firmware upgrades for the above systems, reference the following documents:

• <Document:1540816.1> - "SPARC M5-32 and M6-32 Servers: Firmware Image Software Version Matrix Information"
• <Document:1558958.2> - "Information Center: SPARC M5-32 and SPARC M6-32 Servers"

History

06-Mar-2014: Document released; State: Resolved

Internal Section: Comments:

It is preferred that customers upgrade to System Firmware version 9.1.1.b or later for all fan module replacements.  If the customer
cannot upgrade system firmware a workaround may be possible.

Bug 18169500 only prevents the use of ADM1023 chips of vendor ID 0x55 when they are placed in scalability slots (i.e., FM16 through
FM19).  Service processor snapshot data can be provided to TSC for the selection of a DCU fan module to be swapped into the
scalability slot position.  The fan module FRU can be placed in a DCU slot and a previously existing DCU fan module can be placed into
the scalability slot.  TSC must verify a proper candidate fan module and assure available fan redundancy will permit the swapping
operation.
