The table below lists and explains names and meanings of the IP parameters. These values are tuned by editing the /etc/default/LifeKeeper configuration file.

Notes
IP_PINGTRIES Number of ping retries that will be performed during an IP health check. Integers 3 As required
IP_PINGTIME Time in seconds that LifeKeeper waits for one packet ping reply during IP health check. Integers 1 As required When using a manually configured Ping List rather than the broadcast ping mechanism, any value greater than 3 for this tunable is ineffective, because the Linux TCP/IP implementation always returns a “Destination Host Unreachable” error after 3 seconds with no reply, regardless of the timeout value specified in the ping command.
NOIPUNIQUE Disables the IP uniqueness checking done when an IP resource is brought in-service. By default LifeKeeper will ensure the IP address is not in use somewhere else on the network.

NOBCASTPING Disables the broadcast ping mechanism for checking the health of IP resources.

IP_MAX_LINKCHK The maximum number of seconds to wait for the link to come back up after it has been repaired. In some environments, it may be necessary to increase this value. Integers 5 As required
IP_WAIT_LINKDOWN Number of seconds to wait in between taking the protected network interface down and back up. A delay between these two actions is necessary in some environments. Integers 5 As required
