Compatibility Information and Installation Requirements

• hacl-dlm 5408/tcp
Serviceguard also uses port 9/udp discard during network probing
setup when running configuration commands such as cmcheckconf or
cmapplyconf and cmquerycl. If the port is disabled (in inetd.conf), the
network probing may be slower and under some conditions error
messages may be written to syslog.
Serviceguard also uses dynamic ports (typically in the range of 49152 -
65535) for some cluster services. If you have adjusted the dynamic port
range using kernel tunable parameters, alter your rules accordingly.
System Firewalls
When using a system firewall such as HP-UX IPFilter with
Serviceguard, you must allow specific communications to ensure proper
cluster operation. Specific IPFilter rules required by Serviceguard are
documented in the HP-UX IPFilter Administration Guide, available from
http://www.docs.hp.com -> Internet and Security Solutions.
