Thanks Dave, 

We created new hostnames for both machines (briscoe-i & mccoy-i) that
resolve to their proper internal ip addresses.  However, clvmd still
gets that message and then goes into "Ds" state.  Here's the output of
cman_tool status from both nodes:

---
[root at briscoe-i ~]# cman_tool nodes
Node  Votes Exp Sts  Name
   1    1    1   M   mccoy-i
   2    1    1   M   briscoe-i

So now I'm at a loss as the IP addresses match their hostnames in our
DNS system now.
