changing IP with scyld

I'm working on a small cluster running Scyld.  Recently I changed the IP 
addresses range of the nodes and also the ip of the master in 
/etc/beowulf/config.  After rebooting, the nodes appear to be Up but 
Unavailable in BeoStatus.  At this point I can run mpi_mandel as root.  
However, if I make the nodes available with BeoSetup, I can no longer run 
any mpi programs.

I get the following error:
[root at grendel /root]# NP=8 mpi_mandel
p0_10360:  p4_error: net_create_slave: bproc_rfork: -1
    p4_error: latest msg from perror: Input/output error
bm_list_10363:  p4_error: interrupt SIGINT: 2
[root at grendel /root]#

Are there other files that I need to update with the new IP information?

Thanks for your time,
Johannes Gröhn
