+It is quite common to use multiple ethernet adaptors for cluster nodes, so
+they will tolerate the failure of one link. A common way to do this is to use
+ethernet bonding. Alternatively you can get openais to run in redundant ring
+mode by specifying an 'altname' for the node. This is an alternative name by
+which the node is known, that resolves to another IP address used on the
+other ethernet adaptor(s). You can optionally specify a different port and/or
+multicast address for each altname in use. Up to 9 altnames (10 interfaces
+in total) can be used.
+
+Note that if you are using the DLM with cman/openais then you MUST tell it
+to use SCTP as it's communications protocol as TCP does not support
multihoming.
