Combine Data Address and Test Address for Single IP Network Multipathing Group

This feature is new in the Software Express pilot program and in the Solaris 9 12/02 release. This feature is included in the Solaris 10 3/05 release.

The use of a dedicated test IP address for failure detection on single-adapter IP network multipathing groups is no longer required. Sometimes, failover is not possible because only one network interface card (NIC) is in an IP network multipathing group. In this situation, you can now combine the test address and the data address. The in.mpathd daemon uses a data address to detect failure when a test address is not specified.

For further information on Solaris IP multipathing, see Part VI, “IPMP,” in the System Administration Guide: IP Services. See also the in.mpathd(1M) man page.
