Issue Description: 

Main Fan 6 and Main Fan 7 failures can cause reduced system
availability in Sun Fire V1280 and Netra 1280 servers.  The impact to
system operation will depend upon the number of System Boards installed
and upon the ambient temperature.  In the worst case scenario, the
system will reboot with one or more System Boards disabled.  This FIN
describes the different failure modes and the service procedures
required for recovery.

This issue affects any Sun Fire V1280 or Netra 1280 server in which
Main Fan 6 or Main Fan 7 has slowed down or has failed.

When this issue occurs, a Fan will fail and LOM errors will be
displayed on the console and in the LOM log files.  The fault LED
located on the faulty Fan will be lit.  The Service Engineer should
determine appropriate action by inspecting the Fan to see if it is
still spinning or has stopped completely.  Reference the Service Manual
for the location of the 8 Fans.
     
Systems Operating at up to 35�C Ambient Temperature:
====================================================
     
Configuration: 4 x CPUs (SB0)
     
   Any main system fan failure can be resolved with hot-swap procedure.
   There is no impact to system availability.
     
Configuration: 8 x CPUs (SB0 & SB2)
     
   If main system Fan(s) 0, 1, 2, 3, 4, 5 or 7 are running slow or have
   stopped, the system will report alarms but will continue to
   operate.  These failures can be resolved with a hot-swap procedure.
   There is no impact to system availability.

   If main system Fan 6 has stopped, the system will reboot with SB2/P2
   disabled within 9 minutes.  The customer should plan a service
   action to replace the failed Fan. The Fan can be hot-swapped if
   SB2/P2 has been disabled.
     
   Customer will need to re-enable the blacklisted CPU SB2/P2.
      
      # cfgadm -c unconfigure N0.SB2 
      SC> enablecomponent SB2/P2
      # cfgadm -c configure N0.SB2

     
   If main system Fan 6 is running slow, the system will report 
   alarms but will continue to operate.  The customer should plan a 
   service action to bring the system down to replace the faulty fan. 
   Consideration should be given to exchanging the entire Fan Tray 
   assembly as a preventative maintenance action for any other
   failures.
 
Configuration: 12 x CPUs (SB0, SB2 & SB4)
     
   If main system Fan(s) 0, 1, 2, 3, 4, 5 or 7 are running slow or have
   stopped, System will report alarms but will continue to operate.
   These failures can be resolved with hot-swap procedure.  There is no
   impact to system availability.

   If main system Fan 6 has stopped, the system will reboot with SB4/P2
   disabled within 7 minutes and again reboot with SB2/P2 disabled
   within 9 minutes.  The customer should plan a service action to
   replace the failed Fan.  The Fan can be hot-swapped if SB4/P2 and
   SB2/P2 has been disabled.

   The customer will need to re-enable the blacklisted CPU(s) SB2/P2
   and SB4/P2.
      
      # cfgadm -c unconfigure NO.SB4 
      SC> enablecomponent SB4/P2
      # cfgadm -c configure NO.SB4 
      # cfgadm -c unconfigure NO.SB2 
      SC> enablecomponent SB2/P2
      # cfgadm -c configure NO.SB2
     
   If main system Fan 6 is running slow, the system will report alarms
   but will continue to operate.  The customer should plan a service
   action to bring the system down to replace the faulty fan.
   Consideration should be given to exchanging the entire Fan Tray
   assembly as a preventative maintenance action for any other
   failures.

Systems Operating between 35�C and 40�C Ambient Temperature:
============================================================
     
Configuration: 4 x CPUs (SB0)
      
   If main system Fan(s) 0, 1, 2, 3, 4, 5 or 6 are running slow or have
   stopped, the system will report alarms but will continue to
   operate.  These failures can be resolved with hot-swap procedure.
   There is no impact to system availability.

   If main system Fan 7 has stopped, the system will reboot with SB0/P2
   disabled within 9 minutes.  The customer should plan a service
   action to replace the failed Fan.  The Fan can be hot-swapped if
   SB0/P2 has been disabled.

   The customer will need to re-enable the blacklisted CPU SB0/P2.

   First, prepare services / databases / apps etc. for a Solaris
   shutdown then

     lom> shutdown
     lom> enablecomponent SB0/P2
     lom> poweron

   Then restart services / databases / apps etc.
           
   If main system Fan 7 is running slow, the system will report alarms
   but will continue to operate.  The customer should plan a service
   action to bring the system down to replace the faulty fan.
   Consideration should be given to exchanging the entire Fan Tray
   assembly as a preventative maintenance action for any other
   failures.
     
Configuration: 8 x CPUs (SB0 & SB2) 
     
   Affected by both Fan 7 and Fan 6 failures as previously described.
     
Configuration: 12 x CPUs (SB0, SB2 & SB4) 
     
   Affected by both Fan 7 and Fan 6 failures as previously described.
         
To aid in diagnosing and servicing the Fan issues described above,
information is being added to the following documents:

   . The Product Notes will be updated in time for RR of the Sun Fire 
     V1280. 
   . The Service manual will be updated for RR of the Netra 1280. 
   . Service training material will be updated by GA of the product.
   
In addition, Caution Labels are to be fitted adjacent to Fan 6 and Fan 7.

      /!\ DISABLE SB4/P2 AND SB2/P2 BEFORE REMOVING FAN 6 |

      /!\ IF AMBIENT >35C DISABLE SB0/P2 BEFORE REMOVING FAN 7 |
      ---

Engineering are responding to an RFE to allow only a single system
reboot on Fan 6 failures.  This enhancement is planned to be
implemented in release 10 of the SC Firmware, and release is planned
for GA of the product.

Implementation: 

---
        |   |   MANDATORY (Fully Proactive)
         ---    
         
  
         ---
        |   |   CONTROLLED PROACTIVE (per Sun Geo Plan) 
         --- 
         
                                
         ---
        | X |   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.    
    
When Main Fan 6 or Main Fan 7 failures are discovered for Sun Fire
V1280 or Netra 1280 systems, follow the recovery procedures described
in the Problem Description above.   For further information regarding
this issue, see Sun Fire V1280/Netra 1280 Service Manual, 817-0510-10,

Comments: 

None.

============================================================================

Implementation Footnote: 

i)   In case of MANDATORY FINs, Sun Services will attempt to contact   
     all affected customers to recommend implementation of the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Sun 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, Sun Services will implement the FIN as the   
     need arises.
