NetWare 6.5, 4-node Cluster 1.7 - Life was good for years... until last

Nodes lost connectivity to fiber SAN. Once connectivity was restored,
everything 'seemed' to load correctly.

However, volumes do not show up in SLP - can't back them up or find them via
FTP UNLESS they are mounted on the master node Everything functions fine if
loaded on master (though still not displayed with display slp services).

I've deleted and recreated one of the resources, its recreates fine and is
usable; however, still no entry in SLP.

My next thought is downing the cluster and recreating the SBD partition -
which I've never done and does intimidate me.
