hacl-cfg 5302/tcp # HA Cluster TCP configuration
hacl-cfg 5302/udp # HA Cluster UDP configuration
hacl-probe 5303/tcp # HA Cluster TCP probe
hacl-probe 5303/udp # HA Cluster UDP probe
hacl-local 5304/tcp # HA Cluster Commands
hacl-test 5305/tcp # HA Cluster Test
hacl-dlm 5408/tcp # HA Cluster distributed lock manager
Check this from every node to every other node of the cluster:
# telnet localhost hacl-cfg
# telnet <own hostname> hacl-cfg
# telnet <other hostname> hacl-cfg
The telnet commands should simply hang, which is the normal behaviour if you reach the remote
cmclconfd. Messages like “connection refused“ or “hacl-cfg: bad port number“ indicate
a problem.
Example 2
Error: Node Node1 is refusing Serviceguard communication.
Please make sure that the proper security access is configured on node
Node1 through either file-based access (pre-A. %s version) or role-based
access (version A.11.16 or higher) and/or that the host name lookup on node
Node2 resolves the IP address correctly. cmcheckconf: Failed to gather
configuration information
The reason for this error message could be:
 The file cmclnodelist is incorrect
 network issue
For troubleshooting try to add a + in the cmclnodelist file.
If there is a network issue:
Check the network: nslookup, nsquery, telnet
Check the lan configuration
• Error: Non-uniform connections detected
This error is usually the result of a misconfiguration of a network component. The dominant
errors are mismatching speed/duplex of a LAN interface, sometimes even assigning the same
link level address to more than one interface. The problem occurs while Serviceguard probes the
IP or link level connectivity between all interfaces that are part of the cluster configuration. The
probing result needs to be always symmetrical. Traffic needs to pass either in both or no
direction!
