WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
System Controller Application (ScApp), lom

Task Complexity: 4

Time Estimate: 120 minutes

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW:
Memory Dimm Replacement

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

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

1) Determine if it is possible to utilize Dynamic Reconfiguration (DR) for this replacement.

You can not utilize DR is if the board contains kernel or permanent memory. You can validate if it does by issuing the following command on the domain:

$ cfgadm -av | grep -i perm

If the board is listed in the result, you can not use DR.

2a) If able to use DR, disconnect the board from the domain. On the domain do:

$ cfgadm -c disconnect N0.SB#

2b) If unable to use DR, halt the domain, and power off the board. On the domain do:

$ halt
or
$ init 0

Then, on the Main SC or from the lom prompt do:

SC> poweroff SB#

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

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

1) Perform the physical DIMM(s) replacement (Service Manual links below).

2) Power on the board again. On the Main SC or from the lom prompt:

SC> poweron SB#

3) Verify the CHS status of ALL remaining components. On the Main SC or from the lom prompt:
SC> showchs -b
4) Reset any "Suspect" or "Faulty" components to "ok":

lom> setchs -s OK -r "SR number" -c <comp>

NOTE: If ScApp 5.20.15 or higher, service mode access IS NOT 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 reset.

Verify "showchs -b" is empty.

5) Consider setting the domain's diag_level to max to execute extended POST on the new hardware. On the domain:

$ eeprom diag-level=max
or if at the ok prompt:
ok> setenv diag-level max

6a) If able to use DR, configure the board back into Solaris. On the domain:

$ cfgadm -c configure N0.SB#

6b) If unable to use DR bring the domain back up (power cycle is suggested). On the Main SC or from the lom prompt:

SC> setkeyswitch -d (domainID) off
SC> setkeyswitch -d (domainID) on

7) Monitor the POST execution (will appear on the domain console).

* If new errors are detected, collect POST and contact Support.
* If not, the service is complete.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot the system if it's not already booting.
