Error description

  • In HACMP 6 with rsct.core.utils 3.1.4.9 or higher, if all
    IP networks are lost and at least one non-IP network is
    functioning, the Group Services subsystem will core dump when
    trying to send packets to be routed through Topology Services
    (across the non-IP connection).  This will cause a node halt.
    
    Customers with PowerHA 7, or HACMP 6 customers with no non-IP
    networks (such as rs232 or disk) are not in danger.  Also this
    will not happen if only one node is still running, since there
    will be no other cluster members to send messages to.
    

Local fix

Problem summary

  • Due to internal coding issues, there is a weakness in the
    code path followed under "daemon routing" activity.  As a
    result, under HACMP v6 and older releases, using RSCT code
    starting at rsct.core.utils 3.1.4.9, loss of all IP
    networks when a cluster has non-IP networks available will
    lead to a core dump of the grpsvcs subsystem, which will
    trigger a node halt by the HA code.
    

Problem conclusion

  • The cause of the core dump has been resolved.
