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.
|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_NOLINKCHECK||Disables the link status check portion of the IP health check.||
|0||As required||This setting may need to be disabled on virtual environments, specifically after this message in the logs “Link check failed for virtual IP”.|
|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|
