Prepare to Remove an SP

SPARC M8-8 and SPARC M7-8 servers have two SPs in the CMIOU chassis. SPARC M7-16 servers have two SPs in the switch chassis. On all servers, one SP serves as the Active SP, and one serves as the Standby SP. The Active SP manages DCU activity and all system resources unless it can no longer do so, in which case the Standby SP assumes its role.


Note -  Replace only one SP in the system at a time.

Note -  If you issue the prepare_to_remove command for an SPM, you must also prepare the SP for removal. You must then return the SP to service for the SPM to restart. This automatically happens when an SP is physically removed and installed into the slot, but if you do not physically install an SP into the slot, you must issue the return_to_service command for the SP. See Return a Component to Service.

This procedure explains how to prepare an SP for removal. For information about preparing to remove the SPPs in a SPARC M7-16 server, see Prepare to Remove an SPP (SPARC M7-16).

  1. Determine which SP requires service.

    See Identify Faulted Components and SP General Status LEDs.

  2. Ensure that the SPM on the SP is not managing hardware.
    -> show /System/Other_Removable_Devices/Service_Processors/
        Service_Processor_x/Service_Processor_Module_0 state_sp
        Properties:
        state_sp = OffDuty 

    Note -  For SPARC M8-8 and SPARC M7-8 servers with two PDomains, perform this step for the second SPM. For example, if you previously ran the state_sp command on Service_Processor_0/Service_Processor_Module_0, you now need to run it on Service_Processor_0/Service_Processor_Module_1.
  3. For SPARC M8-8 and SPARC M7-8 servers only, verify that the PCIe devices are offline.
    • For SPARC M8-8 and SPARC M7-8 servers with two PDomains, check the state for both SPMs.
      -> show /System/Other_Removable_Devices/Service_Processors/
          Service_Processor_x/Service_Processor_Module_0 state_pcie
          Properties:
            state_pcie = Offline
      -> show /System/Other_Removable_Devices/Service_Processors/
          Service_Processor_x/Service_Processor_Module_1 state_pcie
          Properties:
            state_pcie = Offline
    • For SPARC M8-8 and SPARC M7-8 servers with one PDomain, check the state for the only SPM.
      -> show /System/Other_Removable_Devices/Service_Processors/
          Service_Processor_x/Service_Processor_Module_0 state_pcie
          Properties:
            state_pcie = Offline

    If state_pcie returns a value of Online, log onto the host that contains the SPM and prepare the PCIe card for removal by taking the devices offline for the appropriate SP/SPM slot. See Servicing PCIe Cards.

  4. Determine your next step based on your server Oracle ILOM version.

    SPARC M7 servers running Oracle ILOM version 4.0.x do not require you to prepare the SPM for removal. SPARC M8-8 servers ship with a minimum Oracle ILOM version of 4.0.x.


    Note -  Always update your system firmware to latest available and supported version for optimal performance, security, and stability.
    • For servers running Oracle ILOM version 4.0.x, or a future supported version, go to Step 6.
    • For servers running Oracle ILOM version 3.2.x, continue to Step 5.
  5. (Oracle ILOM 3.2.x only) Prepare the SPM for removal.

    Note -  If your server is running Oracle ILOM version 4.0.x, or a future compatible version, do not perform this step.
    -> cd /System/Other_Removable_Devices/Service_Processors/
        Service_Processor_x/Service_Processor_Module_0
    -> set action=prepare_to_remove

    This command can take several minutes to complete.

    Determine your next step:

    • For SPARC M8-8 and SPARC M7-8 servers with two PDomains, perform this step for the second SPM, and then go to Step 6.

    • For SPARC M8-8 and SPARC M7-8 servers with one PDomain, go to Step 6.

    • For SPARC M7-16 servers, go to Step 7.

  6. For SPARC M8-8 and SPARC M7-8 servers only, verify that the PCIe devices are offline.
    • For SPARC M8-8 and SPARC M7-8 servers with two PDomains, check the state for both SPMs.
      -> show /System/Other_Removable_Devices/Service_Processors/
          Service_Processor_x/Service_Processor_Module_0 state_pcie
          Properties:
            state_pcie = Offline
      -> show /System/Other_Removable_Devices/Service_Processors/
          Service_Processor_x/Service_Processor_Module_1 state_pcie
          Properties:
            state_pcie = Offline
    • For SPARC M8-8 and SPARC M7-8 servers with one PDomain, check the state for the only SPM.
      -> show /System/Other_Removable_Devices/Service_Processors/
          Service_Processor_x/Service_Processor_Module_0 state_pcie
          Properties:
            state_pcie = Offline

    If state_pcie returns a value of Online, log onto the host that contains the SPM and prepare the PCIe card for removal by taking the devices offline for the appropriate SP/SPM slot. See Servicing PCIe Cards.

  7. (Oracle ILOM 3.2.x only) Verify that the SPM on the SP is ready for removal.
    -> show /System/Other_Removable_Devices/Service_Processors/
        Service_Processor_x/Service_Processor_Module_0 health
        Properties:
          health = Offline

    Note -  For SPARC M8-8 and SPARC M7-8 with two PDomains, perform this step for the second SPM.
  8. Prepare the SP for removal.
    -> cd /System/Other_Removable_Devices/Service_Processors/
        Service_Processor_x
    -> set action=prepare_to_remove

    This command powers off the SP and lights the blue Ready to Remove LED on the SP.

  9. Verify that the SP is ready for removal.
    -> show /System/Other_Removable_Devices/Service_Processors/
        Service_Processor_x health
        Properties:
          health = Offline
