Serviceguard for Linux Version A.11.16 Release Notes
Compatibility Information and Installation Requirements
Chapter 1 17
System Requirements
The memory requirement for HP Serviceguard for Linux A.11.16
depends on the number of packages configured in the cluster. To
calculate a rough estimate of how much lockable memory is needed:
Total Memory = 6 MB (for the HP Serviceguard for Linux base) + 80 KB
(for each package in the cluster)
For example, if you have 10 packages in the cluster, you would require
800 KB (80x10), plus 6 MB for a total of 6.80 MB.
The total amount is needed on all nodes in the cluster, regardless of
whether a given package is on that node or not.
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 Discard
• hacl-qs 1238/tcp HA Quorum Server
• hacl-hb 5300/tcp High Availability (HA) Cluster heartbeat
• hacl-hb 5300/udp High Availability (HA) Cluster heartbeat
• hacl-gs 5301/tcp HA Cluster General Services
• 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
The ports reserved for authentication are also used by Serviceguard:
• auth 113/tcp authentication
• auth 113/udp authentication
In addition, Serviceguard also uses dynamic ports (typically in the range
49152-65535) for some cluster services. If you have adjusted the dynamic
port range using kernel tunable parameters alter your rules accordingly.
