You can use the CC interfaces but you'll be missing out on some of the

These two questions concern me. Are you planning on having one of the
nodes in the VAxcluster act as the PCM engine? If so then this is
unsupported because if you lose quorum in the cluster then you have lost
the consoles for *all* nodes in the cluster. The PCM engine needs to
be independent of the nodes it services.

It's no big deal to install PCM and configure it. This kinda confirms
what I mentioned above about PCM being installed on the cluster it
manages. This question tells me that that was the plan. Don't do it!

About questions two and three, its just that this customer is
extremely paranoid about up time of this production VAXcluster and
I thought by adding in one node at a time was a good idea to alleviate
some of their fears. They usually test things out alot before putting
them into production.

| Then maybe I misread your question. As stated, it sounded like you were
going to install the PCM software onto a node in the Cluster you were
going to manage with PCM and this is a no-no. The PCM engine needs to be
independent of any cluster that it manages. If the engine is
independent and you asking if you can add just one node - sure no
problem. There should be *no* downtime necessary on any of the managed
nodes.
Regs,
