Issue



Intermittent failures and possible system crashes are known to occur when using Storage Foundation for UNIX, (SF/HA) Veritas Cluster Server, (VCS) Storage Foundation for Oracle RAC, (SFRAC) and Storage Foundation Cluster File Server (SFCFS) with certain AIX platforms.

Solution




Problem 1:
System Crashes/Hangs

System either crashes or hangs in one of the drivers of Veritas cluster solutions. Crash or hang will occur with any version of clustering products based on 4.0 or 5.0 including the recent extension release to 5.0MP1, called 5.0MP1 Update 1 for AIX 6.1, released in early March 2008. The Service Pack releases of AIX with the patch levels specified in the following table are the levels of AIX which result in this problem.


 
O/S LevelStorage FoundationVeritas Cluster ServerStorage Foundation High AvailabilityStorage Foundation Cluster File ServerStorage Foundation Oracle RAC

AIX 5.3 TL6 SP5NOYESYESYESYES
AIX 5.3 TL7 SP2NOYESYESYESYES
AIX 6.1 Base SP3NOYESYESYESYES
 


If your system is upgraded to or installed at the specified levels or above, you are impacted. You must follow the recovery instructions provided below to recover.

Problem 1 Solution: LLT patches are available from TechNote 300765.

NOTE#
Please refer to TechNote 300765 below under the Related Documents section for the latest updates and LLT patches.

NOTE#  Removal of IBM temporary patch. (Workaround)

Once the LLT patch is installed, the workaround patch can be uninstalled, if it was installed.

To uninstall the IBM workaround patch:

For AIX 6.1:
  # emgr -rL 61TL00dlpi
For AIX 5.3 TL6:
  # emgr -rL 53TL06dlpi
For AIX 5.3 TL7:
  # emgr -rL 53TL07dlpi


Problem 2: Intermittent Failures

SFRAC fails intermittently in OCE environment on AIX 6.1. This problem occurs only on AIX 6.1 with Oracle 10g and applies only to SFRAC 5.0MP1 Update 1 for AIX 6.1 release. Symantec has observed this problem while certifying SFRAC on AIX 6.1 with Oracle 10gR2. The symptoms may be many, however. Symantec has observed Oracle error code of ORA-15180 during Oracle certification, and the error message "IBM/AIX RISC System/6000 Error: 29: Illegal seek" from Oracle 'listener' process tnslsnr.

IBM and Symantec are jointly working together to investigate the cause of this problem. Unfortunately, this problem prevents Symantec to support Oracle 10gR2 with SFRAC on AIX 6.1. At this point SFRAC 5.0MP1 Update 1 for AIX 6.1 is not certified to support Oracle 10gR2.
