Bug Id
<SUNBUG: 6684726>, <SUNBUG: 6699498>

Date of Preliminary Release
12-Jun-2008

Date of Resolved Release
01-Aug-2008

Sun Fire Server with Solaris 10 may Panic or Reset with lpost message, asynchronous event, fail to stop CPU or send_mondo timeout. (see below for full details)

1. Impact

Loss of application availability may occur due to a system panic or reset. This type of fault is typically diagnosed to be a hardware failure and may lead to unnecessary hardware replacement.

2. Contributing Factors

This issue may occur on the following releases and platforms:

SPARC Platform
  • Solaris 10 with Sun Fire E6900/E4900/E2900/6800/4800/4810/3800/V1280 Netra 1280 and Netra 1290 Systems and without patches 114527-11 (FW) and 137111-04 (Kernel)
Notes:

This issue is specific to the Midrange servers listed above and only seen with SPARC USIV+  1.5GHz and 1.8GHz CPUs.
It is considered possible to occur with USIV+ 1.95 GHz CPU.

Current firmware versions of System Controller (ScApp) ScApp:5.20.9  (as delivered in patch 114527-10) and earlier are affected.

It has been observed when running programs that access OBP from the OS.  Examples of programs that access OBP from the OS are prtdiag, prtconf, cfgadm, picl, or other third party System management software.

This issue is very timing dependent and expected to be rare.

3. Symptoms

Console logs and core files are useful in identifying whether the system is experiencing
this issue.

The fix will require a firmware upgrade to System Controller
Application (ScApp) 5.20.10 in patch 114527-11
and the Solaris 10 kernel patch. As a workaround the
command seen in the core file that caused the failure at a
customer's site should be disabled to prevent repeat failures.
This timing issue is load dependent, and a machine that has
seen the issue has a higher potential for seeing the issue again.
It is not recommended to proactively disable all commands
in the Contributing Factors section, since the application mix required
to initiate the failure is rare.
