The Question is:
I have a four node VMS cluster with two FDDI cards in each node. There are two
rings campus wide. How can I tell which ring is being used for cluster traffic?
The Answer is :
The OpenVMS Cluster software will configure and will make use of all
available paths -- this might involve just periodic probing of the
path for continuity, or it might involve extensive cluster traffic
traversing the path.
You can explicitly select a path to use via various means, and any
cluster path failure will cause a fail-over to the best available
remaining path. (For purposes of recovery, the failed path will
continue to be periodically probed.) For one tool that can be used
to control the cluster path, see SYS$EXAMPLES:LAVC$STOP_BUS.*.
