FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

Customer should fail-over to the OTHER SC and disable SMS failover

Preparation:
Note: Before shutting down and replacing an SC make sure that clock from the other SC to all components is in a good state. To check this run "showboards -c" command for SMS 1.4 and later. ( See *Document ID: 1006413.1 Check clock status before replacement of System controller for more information )

As user sms-svc (or another user with platform privileges), verify:
- that the other SC is MAIN (showfailover -r)
- that the other SC is the current clock source (showboards -c)
- that failover is disabled (showfailover)
- shut down SC with faulty drive ("init 0"), then power it off from the main using "poweroff scX"

Physical Replacement:
- Unseat the SC board. SCs have been known to automatically power on, which can cause problems during this procedure.
- Remove the SC Peripheral board (the tape drive and DVD drive are externally visible here).
- Replace the power board cable
- IMPORTANT: Insert the SCPER board FIRST, then insert the SC board LAST.

Poweron spare SC:
- "poweron scX"
- Observe boot sequence, ensure no errors appear
- Wait for SMS to start, then enable failover "setfailover on"
