This may seem like a dumb question but I'll ask anyway. Do all cluster
resources need an IP address ? The reason for asking is that I have some
software installed on a volume that is already part of a cluster and the
mounting and dismounting of the volume is already taken care of. I have no
need to address the application via its IP address (it hasn't got one).
Should I get away with

Load application


Unload application

(I know I can but thats not the point)or should each resource on a cluster
require an ip address eg ADD SECONDARY IPADDRESS a.b.c.d
