VCS

[Sunspot]

I need to install (no reboot) a simple monitoring agent on a solaris server
running VCS. Do I need to stop HAD or freeze it, or is it fine to install
while running VCS?

AFAIK, by default VCS doesn't understand the underlying applications... so
I'd think it would be safe to do (thus one cluster node could be running
different applications from another... doing the application level clustering
requires end user work/config).

[Sunspot]

That was my thought, because unless you set it as a resource it doesn't
matter.

It is certainly *possible* to add a new Type and then resource to VCS
while online. However, it's not necessarily trivial. Are you just
adding a new instance (resource) of an existing agent, or are you adding
an entirely new agent (Type) to the cluster?

In many cases it's easier to shut down the cluster (not the running
applications), then restart with a modified main.cf.

But you wouldn't want to do either one on a production cluster without
testing or knowing what you were doing. Understand how it works, test
it, then put it in place.

It is a clustered file system and I am simply adding an EMC ECC Master Agent
to monitor SAN disk space. Why would I want VCS to manage it? The server
will be decommed in 4 months.

If you say "VCS server" and "agent" in the same post, I'm going to
assume you're talking about a "VCS agent".

If you install random software on a VCS server that has no interaction
with the cluster (like sendmail or SSH), then VCS doesn't care.
