Enable or Disable SAS2 From Oracle ILOM

By default SAS2 links are disabled on the SAS2 expander firmware for the NEM. To enable SAS2 links and to allow server modules with supported REMs to communicate with the Sun Blade Storage Module M2, you must enable SAS2 from Oracle ILOM.


Note - If you enabled SAS2 during a prior release, it stays enabled during and after the upgrade, and no other steps are required. When SAS2 is disabled, the fru_extra_1 field shows SAS 5.3.2.0 in the output of the show /CH/NEMx command (where x is the NEM's slot number) from the CMM level. When SAS2 is enabled, the fru_extra_1 field shows SAS 5.3.7.0 in the output of the show /CH/NEMx command (where x is the NEM's slot number) from the CMM level.
  1. Display the current SAS2 status.
    -> cd /NEM/SAS/
    /NEM/SAS
    /NEM/SAS-> ls
       Targets:
     
       Properties:
     type = SAS Expander
    sas_status = disabled
    Commands:
    cd
    show
    start
    stop
     
    
  2. Enable or disable SAS2 links.
    • To enable SAS2, select start.
      -> cd /NEM/SAS/
      /NEM/SAS
      -> start
      Are you sure you want to start /NEM/SAS (y/n)? y
      Enabling the device will take approximately 2 minutes...
       
      start: SAS Enabled successfully.
       
      -> ls
       
      /NEM/SAS
          Targets:
       
          Properties:
       type = SAS Expander
      sas_status = enabled
      Commands:
      cd
      show
      start
      stop
      
    • To disable SAS2, select stop.
      -> cd /NEM/SAS/
      /NEM/SAS
      Are you sure you want to stop /NEM/SAS (y/n)? y
      -> stop
      Disabling the device will take approximately 2 minutes...
       
      stop: SAS Disabled successfully.
       
      -> ls
       
      /NEM/SAS
          Targets:
       
          Properties:
       type = SAS Expander
      sas_status = disabled
      Commands:
      cd
      show
      start
      stop
