                       Systems Firmware Update. 

Sun Alert: 46346

URL: http://cpre-amer.west/esg/msg/techinfo/platform/sun_fire/firmware-matrix/
Issue Description: 
The System Controller (SC) on Sun Fire systems installed with firmware
5.11.x (5.11.4 through 5.11.9), may lose its network settings after an
upgrade to 5.13.0, 5.13.1, or 5.13.2.  This may cause problems
communicating with the SC and prevent access to domain consoles. 

This issue can occur in the following releases: 

   Sun Fire Servers (3800/4800/4810/6800) without firmware patch 112494-05. 

NOTES: 

   A. The described issue will also occur if the firmware was previously 
      updated from 5.11.x (5.11.4 through 5.11.9) to 5.12.5 or 5.12.6 and 
      then subsequently upgraded to 5.13.0, 5.13.1, or 5.13.2. 

   B. System Controllers which shipped with 5.12.x firmware are not 
      susceptible to the described issue. 

   C. Use the "showsc" command to display the firmware version of the SC. 

   D. The following lists the firmware patch numbers associated with the 
      firmware level: 

   Patch       Firmware
   ---------------------
   111346-01 == 5.11.4
   111346-02 == 5.11.6
   111346-03 == 5.11.7     
   111346-04 == 5.11.9 currently on SunSolve
        
   112127-01 == 5.12.5 
   112127-02 == 5.12.6
   112127-03 == 5.12.7 currently on SunSolve

   112494-02 == 5.13.0
   112494-03 == 5.13.1
   112494-04 == 5.13.2 
   112494-05 == 5.13.3 currently on SunSolve

Also reference the Sun Fire Firmware Compatibility Matrix at:

   http://cpre-amer.west/esg/msg/techinfo/platform/sun_fire/firmware-matrix/

After updating the firmware, the SC may not be accessible on the
network because all network settings may have been reset to the factory
defaults.  The command 'showplatform -p net' will indicate Dynamic Host
Configuration Protocol (DHCP) is enabled and no other hostname or
network settings are shown. 

Below are examples of booting an affected SC: 
      ...
      Flashupdate completed successfully. 
      The SC is being rebooted to use the new images.

The cause for Bug 4706916 is that the NVRAM, where the network settings
are stored, was improperly initialized by SC Firmware versions 5.11.x.
While the fault in the initialization code was corrected in 5.12.x, the
existing initialization problem caused by 5.11.x is not detected until
an upgrade to 5.13.0, 5.13.1, or 5.13.2 is attempted.  These versions
of firmware improperly treat the initialization error as NVRAM
corruption and reinitialize the NVRAM, causing a loss of all settings
contained in NVRAM.

This issue has been resolved with firmware patch 112494-05 which is
now available from SunSolve.  It provides firmware version 5.13.3.
Implementation: 
---
          |   |   MANDATORY (Fully Proactive)
           ---


           ---
          | X |   CONTROLLED PROACTIVE (per Sun Geo Plan)
           ---


           ---
          |   |   REACTIVE (As Required)
           ---
Corrective Action: 
The following recommendation is provided as a guideline for authorized
Sun Services Field Representatives who may encounter the above
mentioned problem.

1. Upgrade Sun Fire systems to version 5.13.3 using patch 112494-05 
   to avoid encountering Bug 4706916.
   
OR

2. If it is necessary to upgrade from 5.11.X firmmware to a version of
   5.13.X less than 5.13.3, use the following workaround:

   Gather the following output from the SC *BEFORE* proceeding with the 
   upgrade.  This output will allow the user to restore any settings which 
   may be lost as a result of encountering Bug 4706916:
    
	'showplatform -v'
	'showboards'
	'showplatform -d ' (for each domain)
	OBP settings from each domain using the 'printenv' command
	    from the  prompt and the 'devalias' command also 
	    from the  prompt

   Further, flashupdate commands should be issued from the serial port
   of the SC (not via a network connection) in order to watch the update
   and reboot processes for errors, and to maintain control of the SC in
   the event network settings are lost.

============================================================================
Implementation Footnote: 
i)   In case of MANDATORY FINs, Enterprise Services will attempt to    
     contact all affected customers to recommend implementation of 
     the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical    
     support teams will recommend implementation of the FIN  (to their  
     respective accounts), at the convenience of the customer. 

iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the   
     need arises.
