Serviceguard Version A.11.16 Release Notes, Second Edition
Compatibility Information and Installation Requirements
Chapter 1 21
NOTE Remember to tune the swap space and the HP-UX kernel parameters
nfile, maxfiles and maxfiles_lim to ensure that they are set high
enough for the number of packages you are configuring.
Port Requirements
Serviceguard uses the ports listed below. Before installing, check
/etc/services and be sure no other program has reserved these ports.
• hacl-hb 5300/tcp
• hacl-gs 5301/tcp
• hacl-cfg 5302/tcp
• hacl-cfg 5302/udp
• hacl-probe 5303/tcp
• hacl-probe 5303/udp
• hacl-local 5304/tcp
• hacl-test 5305/tcp
• 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 it is disabled, the command will
fail and you will get an error message in syslog.
In addition, 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, specific communications must be allowed to ensure proper
cluster operation. Specific IPFilter rules required by Serviceguard are
documented in the HP-UX IPFilter Release Notes, available from
http://www.docs.hp.com -> Internet and Security Solutions.
