  • Closed as program error.

Error description

  • During a failover process of a DPF shared disk HA setup. If a
    kill -9 occurs on the db2sysc the db2nodes.cfg file can get
    corrupted. This is due to the fact that DB2 is updating the
    names in the file to complete the failover, and the kill -9
    interrupting that process causing the update to the file to not
    be completed. This then makes it so DB2 can't read the
    db2nodes.cfg to bring up the nodes.
    

Local fix

  • Recreate the db2nodes.cfg file with the correct names in it.
