NEM STATE (/CH/NEMx/STATE) is Not “Running”

Under normal circumstances the STATE sensor of the NEM will report that the NEM is “Running.” If the NEM is in another state, you might see that one of the SAS paths to storage module resources is missing (two NEMs are required for a dual path connection to disks).

What to look for:

The following table provides examples of how the web interface and CLI might look like when the NEM is not in the “Running” state.

CMM ILOM NEM State is On Line Web interface In CMM—>System Monitoring->Components. CLI -> show show /CH/NEM1/STATE /CH/NEM1/STATE Targets: Properties: type = Module ipmi_name = NEM1/STATE class = Discrete Sensor --> value = On Line alarm_status = cleared Commands: cd show

Things to check:

Confirm that the prepare_to_remove_status is "Not Ready". The NEM should only be in the ready to remove state during a hot plug action. Do the following in the CMM ILOM CLI:

1. Log into the CMM with administrator privileges.

2. Enter the command:

   -> cd /CH/NEMx

   Where x is the slot number of the NEM.

3. Check the prepare_to_remove_status by entering the command:

   -> ls

   Output might look like:

    /CH/NEM1
       Targets:
           MB
           SAS
           SP
           PRSNT
           STATE
           ERR
           OK
           SERVICE
           OK2RM
           LOCATE
   
       Properties:
           type = Network Express Module
           ipmi_name = NEM1
           system_identifier = SUNSP00212829EE4A
           fru_name = SUN BLADE 6000 VIRTUALIZED MULTI-FABRIC 10GE NEM M2
           fru_version = FW 3.0.10.16, SAS 5.3.5.0
           fru_part_number = 540-7961-02
           fru_extra_1 = FW 3.0.10.16, SAS 5.3.5.0
           fault_state = OK
           load_uri = (none)
           clear_fault_action = (none)
   --> prepare_to_remove_status = NotReady
           prepare_to_remove_action = (none)
           return_to_service_action = (none)
   
       Commands:
           cd
           load
           reset
           set
           show

Actions to perform:

If the prepare_to_remove_status is "Ready", the NEM is offline and in a state for hot plug removal. What you do depends on how it got into that state. Bring the NEM back to its “Running” state by doing one of the following:

• If you put the NEM into the “Ready” state by running prepare_to_remove action=true:

  1. Remove the NEM from the chassis.

  2. Wait 10 seconds or more.

  3. Re-insert the NEM into the chassis.

  4. Press the Attention button.

• If not:

  1. Log into the CMM with administrator privileges.

  2. Enter the command:

     -> cd /CH/NEMx

     Where x is the slot number of the NEM.

  3. Return the NEM to service by entering the command:

     -> set return_to_service_action=true

  4. Then check that the state has returned to “Running” by entering the command:

     -> show /CH/NEMx

     It takes several minutes for the state to return to “Running”.

     Where x is the slot number of the NEM. Output might look like:

      /CH/NEM1/STATE
         Targets:
     
         Properties:
             type = Module
             ipmi_name = NEM1/STATE
             class = Discrete Sensor
     --> value = Running
             alarm_status = cleared
     
         Commands:
             cd
             show

• If the prepare_to_remove_status is "NotReady", but the CH/NEMx/STATE is "On Line". In the CMM ILOM CLI, enter the following commands:

  1. Press the Attention button on the NEM and verify that the state is returned to Running, as described above.

     Instead, you can enter the command:

     -> set return_to_service_action=true

  2. If that does not change the NEM state to “Running”, log into the CMM with administrator privileges.

  3. Enter the command:

     -> cd /CH/NEMx

     Where x is the slot number of the NEM.

  4. Set the prepare_to_remove state to “true” by entering the command:

     -> set prepare_to_remove_action=true

  5. Set the return_to_service state to “true” by entering the command:

     -> set return_to_service_action=true

     This power cycles the NEM and returns the /CH/NEMx/STATE to “Running”.

  6. To check that the state has returned to “Running”, enter the command:

     -> show /CH/NEMx/STATE

     Where x is the slot number of the NEM.

     Note - It can take several minutes for this action to take effect.

     The output might look like this:

      /CH/NEM1/STATE
         Targets:
     
         Properties:
             type = Module
             ipmi_name = NEM1/STATE
             class = Discrete Sensor
     --> value = Running
             alarm_status = cleared
     
         Commands:
             cd
             show

• If there are two NEMs, then the state of this NEM may be inconsistent with the other NEM in the system. To make the NEMs consistent, refer to SAS Path Disappears and ILOM /CH/NEMx/fault_state is "Faulted".
