WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Powering Off a System Control (SC) Board

If this is the main SC ensure the spare SC is available.
Sync the main to the spare

sc% setdatasync backup
If no messages are reported in /var/opt/SUNWSMS/adm/platform/messages and the command completes, the setdatasync backup was successful.
As a superuser on the main SC, make a backup copy of the SMS configuration:

sc# smsbackup directory
From the main SC, failover (switch over) to the spare SC by typing:
sc% setfailover force
On the main SC, verify that it has assumed the main role and that failover is disabled by typing:

sc% showfailover -r
MAIN
sc% showfailover
SC Failover Status: DISABLED
On the main SC, disable the failover mechanism by typing:

sc% setfailover off
Verify the failover is DISABLED by typing:

sc% showfailover
SC Failover Status: DISABLED

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 )
Shutdown the spare sc:

sc_spare# shutdown -y -g seconds -i 0
Power off the spare (inactive) SC from the main SC by typing the following SMS command:

sc% poweroff scx

Remove the SC Board
Replace The SC
Installing the System Control (SC) Board

Ensure any board alignment tabs are not bent.
Inspect the mating connector before inserting the new board.
Apply firm pressure on the front panel of the SC control carrier to connect with the connector on the centerplane support board.
Apply pressure to the top and bottom insert-eject levers simultaneously to ensure the board is properly seated.
reconnect IO Cables.

Verifying the new System Controller.

Monitor the SCPost to ensure there are no errors.

Confirm that SMS sees the SC when powered on by typing the following SMS command:

sc% showboards -v |grep SC
SC0         On      SC         Spare         -          -
SC1         On      SC         Main          -          -
