IV61874: HA FILESYSTEM IS AUTOMATICALLY REMOUNTED BY TSA WHILE THE DB2 INSTANCE IS STOPPED

DB2 Version 9.7 Fix Pack 10 for Linux, UNIX, and Windows

APAR status

• Closed as program error.

Error description

• On an AIX system, where the DB2 instance has been configured for
  high availability via the db2haicu utility. If a highly
  available file system is unmounted while the DB2 instance is
  stopped, TSA will automatically remount the file system.
  
  In order to determine if a file system is highly available, the
  following two commands can be executed:
  
  export CT_MANAGEMENT_SCOPE=2
  lsrsrc -s "StartCommand like '%/hafs01/db2inst1/NODE0000' &&
  ResourceType=1" IBM.Application
  
  where '/hafs01/db2inst1/NODE0000' is the mount path of the file
  system in question. If the lsrsrc command returns a result, then
  the file system is highly available.
  
  In order to prevent this automatic unmount from happening, the
  file system must be unmounted and then its underlying volume
  group must be varied off. Once maintenance operations are
  completed for the file system, then the volume group can be
  varied back on and the file system can then be remounted.
