I don't suppose it's possible to duplicate the entry node MVS1N? If it's only
role is to route files, it might be worth fixing the SPOF. Then you could have
dual links and just let one go down with MVS1N.
Another option would be an outboard NJE node that isn't dependent on MVS1N at
all. Use an

One possible way of doing that is for the SVM to que an IEFBR14 type job
to the link and check every n minutes to see if its gone.

You *could* play the automation game. When MVSN goes down, RSCS will
issue a message and try to restart the link. Capture the message and
ROUTE the traffic to a backup node.

I think you could use link groups here. You'd have to define MVS1A and MVS1B to
VM, then create a group MVS1 that contains the MVS1A and MVS1B links. You could
then route files passing through RSCS to GROUP MVS1 and it would pick the first
available link to queue it on. If MVS1A went away, then
