Applies to: 
 
Sun Blade 6000 System - Version: Not Applicable and later   [Release: N/A and later ]
Information in this document applies to any platform.



Symptoms

Fan failure messages may be seen and present on a single blade in the blade chassis housing.
In the following example, we show errors on the blade in slot 1. Other blades in the chassis operate normally.




Checking the ILOM logs we see that messages indicating fan faults are logged:

  /SYS/FM0
    Properties:
        type = Rear Fan
        fault_state = Faulted    <================================= Faulted
        clear_fault_action = (none)

   /SYS/FM1
    Properties:
        type = Rear Fan
        fault_state = Faulted   <================================= Faulted
        clear_fault_action = (none)

  /SYS/FM2
    Properties:
        type = Rear Fan
        fault_state = OK   <================================= OK
        clear_fault_action = (none)

  /SYS/FM3
    Properties:
        type = Rear Fan
        fault_state = Faulted   <================================= Faulted
        clear_fault_action = (none)

 /SYS/FM4
    Properties:
        type = Rear Fan
        fault_state = Faulted   <================================= Faulted
        clear_fault_action = (none)

 /SYS/FM5
    Properties:
        type = Rear Fan
        fault_state = Faulted   <================================= Faulted
        clear_fault_action = (none)

Other blades will show the fan as working and OK.


Blade 0:

  /SYS/FM0
    Properties:
        type = Rear Fan
        fault_state = OK   <================================= OK
        clear_fault_action = (none)

 /SYS/FM1
    Properties:
        type = Rear Fan
        fault_state = OK   <================================= OK
        clear_fault_action = (none)

 /SYS/FM2
    Properties:
        type = Rear Fan
        fault_state = OK   <================================= OK
        clear_fault_action = (none)

  /SYS/FM3
    Properties:
        type = Rear Fan
        fault_state = OK   <================================= OK
        clear_fault_action = (none)

 /SYS/FM4
    Properties:
        type = Rear Fan
        fault_state = OK   <================================= OK
        clear_fault_action = (none)

 /SYS/FM5
    Properties:
        type = Rear Fan
        fault_state = OK   <================================= OK
        clear_fault_action = (none)







Cause


Possible Causes:
  1. Blade firmware issue or chassis firmware issue
  2. Loose seating of the blade module
  3. Slot issue on the chassis defective blade


Note:

There are many blades in the chassis and only the blade on the slot 1 reports the issue. The fan modules are on the chassis and not on the blade.


Solution


Actions to Perform to Attempt to Resolve:
  1. 
Reseat the affected blade. This will ensure that the blade is properly seated and ILOM is power cycled 
  2. 
Swap the blade to a slot that is working. This would ensure that we can isolate if the issue is with blade module or the slot itself
  3. Confirm that the blades and Chassis Management Module (CMM) are on the latest available firmware




In this case the issue was resolved after the blade was reseated.
