Managing Serviceguard Sixteenth Edition, March 2009

Can be changed while the cluster is running.
NETWORK_POLLING_INTERVAL Specifies how frequently the networks configured
for Serviceguard are checked.
Default is 2,000,000 microseconds (2 seconds).
This means that the network manager will poll
each network interface every 2 seconds, to make
sure it can still send and receive information.
Changing this value can affect how quickly a
network failure is detected. The minimum value
is 1,000,000 (1 second) and the maximum value
supported is 30 seconds. The maximum value
recommended is 15 seconds. HP strongly
recommends using the default.
Can be changed while the cluster is running.
