HP Integrity Virtual Machines Installation, Configuration, and Administration Version A.03.50

11.5.4 Polling Interval for Virtual Machine Serviceguard Nodes
Serviceguard failover in Integrity VM can take longer than expected with the default 5-second
network polling interval. To reduce the failover time, reduce the value of the HPVMNETINTVL
tunable to 2.
If your system has Serviceguard installed and you want to make sure that failover of the vswitches
used for Serviceguard takes less than 5 seconds, use a text editor to add or change the following
line in the /etc/rc.config.d/hpvmconf file:
HPVMNETINTVL=n
where n is an integer between 1 and 10 that specifies the number of seconds.
The default value is 5. That is, if the HPVMNETINTVL tunable is not set in the file, the value is
5 seconds. For Serviceguard in Integrity VM configurations, the recommended value is 2.
