HP Serviceguard Version A.11.18 Release Notes, September 2008

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.
• discard 9/udp
• snmp 161/udp
• snmp 162/udp
• hacl-qs 1238/tcp
• clvm-cfg 1476/tcp
• hacl-hb 5300/tcp
• hacl-hb 5300/udp
• hacl-gs 5301/tcp
• hacl-gs 5301/udp
• hacl-cfg 5302/tcp
• hacl-cfg 5302/udp
• hacl-probe 5303/tcp
• hacl-probe 5303/udp
• hacl-local 5304/tcp
• hacl-test 5305/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
leave open the open the ports listed above and follow specific IPFilter rules required
by Serviceguard; these are documented in the HP-UX IPFilter Administration Guide,
available from http://www.docs.hp.com -> Internet and Security
Solutions.
