Bug Id
<BUG: 15422557>

Impact

There are two issues described in this FAB document.

1) The PC check diagnostic scripts for memory only tests 9 DIMMs (or fewer depending on the configuration). If there are more than nine DIMMs it will not report in the event of a faulty DIMM and may result in other parts being replaced needlessly.

2) Additionally, PC Check versions (prior to 6.05b) in the Tools & Drivers may report false positive DIMM errors if run for several hours. False errors could cause unnecessary DIMM, motherboard or cpu replacements because the errors will persist with each diagnostic run, leading the field to replace non-affected parts.

Contributing Factors

For issue 1) above, memory check of DIMMs:

Sun Fire X2200 M2 prior to 1.5a CD

Note: This is the one server with more than 8 DIMMs by default.

For issue 2) above, false positive DIMM errors:

Sun Fire X2200 M2 prior to 1.4 CD
Sun Fire X2100 M2 prior to 1.3 CD

Symptoms

1) Test scripts give no symptom or indication that configurations with more than nine DIMMs are not tested.

2) Here are 2 examples of false positive error messages:

    Failed Disk Test
    Failed Memory Test

Workaround

See CR 6603341 for details on a possible workaround for issue 1). Please contact engineering as needed if a workaround is necessary until the resolution below can be implemented.

Resolution

1) For X2200M2 with more than 9 DIMMS:

Tools & Drivers 1.5a CD

We recommend downloading the latest updates which include the latest SP, BIOS, and PC Check versions at:

2) To correct the false positive errors:

For X2200M2 download the 1.4 CD from:

http://www.oracle.com/technetwork/systems/patches/firmware/release-history-jsp-138416.html#X2200

For X2100M2 download the 1.3 CD from:

Internal Comments

There was no CR for the false memory errors.

There is Bug 6456755 that is very similar but that was for Andromeda and does not mention the X2200 M2 or other platforms.
