Purpose

After a FRU has been replaced, run a high level of post to verify the system integrity and to confirm the diagnosis and the status of the replaced FRU.

Troubleshooting Steps

Some hardware-related failures are hard to diagnose, for example, multibit ECC memory errors.

To verify if the right part has been replaced, run a high level of post after the part replacement. This procedure is for Sun Fire[TM] Servers (12K/15K/E20K/E25K).

Perform the following steps:

1. Choose the post level:

• Level: 32
• What: Tests all locations but keeps pattern count low.
• When: Minimum level that should be run after a hardware replacement
• Level: 64
• What: Tests all locations with all patterns, excepting memory/external cache.
• When: Recommended default level after hardware replacement
• Level: 96
• What: Tests all locations with all patterns, meaning full for memory and external cache tests.
• When: Recommended level after memory or uniboard replacement, or if it is unclear if there is a memory problem or uniboard.  Also, use full for L2 SRAM related problems.

2. Set the post level:

Edit or change the following file to reflect the post level you want to run:
/etc/opt/SUNWSMS/config/[A-R]/.postrc (Pick the domain letter you wish to test.)
Include or change the level of post you want to run, such as "level 64."

3. Run the test and start the domain:

setkeyswitch -d [A-R] on     (Pick the domain letter you want to test.)

4. Remove the .postrc setting for this test.

After the test domain has been brought up, verify the post log in:

/var/opt/SUNWSMS/adm/[A-R]/post
Check if there are any failures and if all the hardware has been included in the domain. If there are problems reported, follow-up trouble shooting steps might be required.
If there are no problems reported, edit the .postrc file for the domain you want to test on location.
Remove the entry in the /etc/opt/SUNWSMS/config/[A-R]/.postrc file you created before the test.

Alternate Method

Running the post without editing the .postrc file:

setkeyswitch -d <Domain ID> -l 96 on
