SPARC T5-1B Server Module Service Manual

Verify a DIMM

1. Access Oracle ILOM.

   See Log Into Oracle ILOM (Service).

2. Set the virtual keyswitch to diag so that POST will run in Service mode.

   -> set /SYS keyswitch_state=Diag
   Set 'keyswitch_state' to 'Diag'
   

3. Reset the host so that POST runs.

   -> reset /System
   Are you sure you want to reset /System (y/n)? y
   

4. Return the virtual keyswitch to Normal mode.

   -> set /SYS keyswitch_state=Normal
   Set 'keyswitch_state' to 'Normal'
   

5. Start the Oracle ILOM fault management shell.

   -> start /SP/faultmgmt/shell
   Are you sure you want to start /SP/faultmgmt/shell
   (y/n)? y
