Error description

  • When putting all the nodes in the pureScale cluster into
    maintenance mode,  "db2cluster -cm -enter -maintenance -all" and
    "db2cluster -cfs -enter -maintenance -all" commands should be
    used.
    
    If each of the nodes are put into maintenance mode without the
    -all option, db2 cluster command fails because there are not
    enough hosts online in the cluster.
    
    -------------------------------
    There are not enough hosts in the RSCT peer domain to enter
    db2cluster maintenance mode. Exit maintenance on another host in
    order to enter maintenance on host1.
    A diagnostic log has been saved to
    '/tmp/ibm.db2.cluster.68tMea'.
    -------------------------------
    
    Rebooting that last host while all other hosts are in
    maintenance will
    cause the cluster to go into a problematic state, where the
    domain
    would not be able to become online.  This fix will aim to
    improve the error message so that the error message will not be
    missed.
