DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

System Controller Application (ScApp)

Time Estimate: 60 minutes

Task Complexity: 4

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW:

System Controller Failure

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

The following "canned" procedure assumes that SC environment is redundant (there are two SCs). If there are two SCs, then domains will not be affected by this procedure.

If the configuration is not redundant, the procedure to replace the SC is more complicated and requires that all domains are shut down prior to the service action plan.

Instead of using the instructions in this document refer to the System Service Manuals referenced at the bottom of this document.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

In the instructions below, examples use a location of "#".

The following "canned" procedure assumes that SC environment is redundant (there are two SCs). DO NOT PROCEED WITH THE FOLLOWING IF YOUR CONFIGURATION IS NOT REDUNDANT. SEE INSTRUCTIONS LISTED ABOVE.

1) Identify if the SC you need to replace is currently the Main SC:

SC> showfailover -v

Main System Controller V2

SC Failover: enabled and active.

Clock failover enabled.

If it is the Main SC, failover to the other SC:

SC> setfailover force

2) Power off the SC (from the new MAIN):

SC> poweroff ssc#

SSC#: powered off

3) Perform the physical replacement (Service Manual links below). When the new SC is inserted, it should power on automatically and load both SCApp and RTOS.

4) Validate the two SCs firmware matches by comparing the output of "showsc" from both SCs. If the firmware does not match follow the patch installation procedures for the relevant firmware version on the surviving controller.

See the following doc for details on the procedure:

Firmware Download and update procedure for Sun Fire[TM] v1280, 3800, 4800, 4810, 6800, E2900, E4900, E6900, and Netra 1280, 1290 systems. (Doc ID 1006281.1)

5) Turn SC Failover back on:

SC> setfailover on

SC Failover: enabled but not active.

Platform.SC: Clock failover enabled.

Platform.SC: SC Failover: private link is up, attempt to sync

Platform.SC: SC Failover: enabled and active.
SC> showfailover
SC Failover: enabled and active.

Action plan is complete.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

If desired, the customer might want to perform an SC failover "setfailover force" to switch the Main SC back to the original configuration, but this is not required.
