Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES ENGINEER NEED:

ScApp, lom

Task Complexity: 4

Time Estimate: 60 minutes

FIELD ENGINEER INSTRUCTIONS

CAP PROBLEM OVERVIEW:
System Board Failure

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

Examples use a board location of '#'

1) See if DR can be used; If the board is listed in 'cfgadm -av | grep -i perm' output, you can't use DR.

2a) If able to DR, issue 'cfgadm -c disconnect N0.SB#'

2b) If unable, issue 'init 0' and then 'poweroff sb#' at SC prompt

WHAT ACTION DOES ENGINEER NEED TO TAKE:

You will need to move DIMMs from the 'old' board to the 'new' one (same slots).

1) Perform physical SB replacement per Service Manual

2) poweron SB# at SC prompt

3) showchs -b at SC prompt

4) Reset any 'Suspect' or 'Faulty' components to 'ok' from the Main SC or from the lom prompt:
setchs -s OK -r "SR number" -c <comp>

NOTE: If ScApp 5.20.15 or higher, service mode access IS NO LONGER REQUIRED to execute setchs.
If < 5.20.15, contact service to obtain a Service Mode password or generate one yourself at https://modepass.us.oracle.com
(a backup server is also available from https://modepass-bak.us.oracle.com)
Repeat 'setchs' command until all components are 'ok'.

Verify 'showchs -b' is empty.

5) Verify new board firmware matches existing boards & SC(s) ('showboards -p proms' at SC prompt).

If needed, copy firmware from a like board 'flashupdate -c (source board) (destination board)'

6) Consider running extended POST (On domain issue 'eeprom diag-level=max' or at ok prompt 'setenv diag-level max').

7) If you're replacing a COD (Capacity on Demand) enabled board refer to
Sun Fire[TM] 12K/15K/E20K/E25K/F3800/Fx800/Ex900/ servers: How to replace a COD CPU/memory board (Doc ID 1002102.1)
for the needed step to follow

8a) If able to DR, issue 'cfgadm -c configure N0.SB#' at domain level

8b) If unable to DR, issue 'setkeyswitch -d (domainID) off' followed by 'setkeyswitch -d (domainID) on'.

9) Monitor POST.
* If new errors are detected, collect POST and contact Support.

OBTAIN CUSTOMER ACCEPTANCE

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

Boot system if not already booting.
