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. | 0: enabled 1: disabled |
0 | As required | |
NOBCASTPING | Disables the broadcast ping mechanism for checking the health of IP resources. | 0: enabled 1: disabled |
0 | As required | |
IP_NOLINKCHECK | Disables the link status check portion of the IP health check. | 0:enabled 1: disabled |
0 | As required | |
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 |
