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.
