Hi all

Finding "in.mpathd Improved failure detection " entries in /var/adm/messages. What is causing this.

TIA

The in.mpathd daemon performs Network Interface Card (NIC)
failure and repair detection. In the event of a NIC failure,
it causes IP network access from the failed NIC to failover
to a standby NIC, if available, or to any another opera-
tional NIC that has been configured as part of the same net-
work multipathing group. Once the failed NIC is repaired,
all network access will be restored to the repaired NIC.

in.mpathd needs a special test address on each NIC for the
purpose of sending and receiving probes on each NIC. Use the
ifconfig command -failover option to configure these test
addresses. The test address must belong to a subnet that is known to the hosts and routers on the link.
