The IP Monitor section of the cluster configuration file will look similar to the following for a subnet on which IP monitoring is configured with target polling.

NOTE: This is the default if cmquerycl detects a gateway for the subnet in question; see SUBNET under “Cluster Configuration Parameters ” (page 109) for more information.

IMPORTANT: By default, cmquerycl does not verify that the gateways it detects will work correctly for monitoring. But if you use the -w full option, cmquerycl will validate them as polling targets.

POLLING_TARGET 192.168.1.254

To configure a subnet for IP monitoring with peer polling, edit the IP Monitor section of the cluster configuration file to look similar to this:

SUBNET 192.168.2.0

IP_MONITOR ON

NOTE: This is not the default. If cmquerycl does not detect a gateway for the subnet in question, it sets IP_MONITOR to OFF, disabling IP-level polling for this subnet; if it does detect a gateway, it populates POLLING_TARGET, enabling target polling. See SUBNET under “Cluster Configuration Parameters ” (page 109) for more information.

The IP Monitor section of the cluster configuration file will look similar to the following in the case of a subnet on which IP monitoring is disabled:

SUBNET 192.168.3.0

IP_MONITOR OFF

NOTE: This is the default if cmquerycl does not detect a gateway for the subnet in question; it is equivalent to having no SUBNET entry for the subnet. See SUBNET under “Cluster Configuration Parameters ” (page 109) for more information.

Failure and Recovery Detection Times

With the default NETWORK_POLLING_INTERVAL of 2 seconds (see “Cluster Configuration Parameters ” (page 109)) the IP monitor will detect IP failures typically within 8–10 seconds for Ethernet and within 16–18 seconds for InfiniBand. Similarly, with the default
