Node C is also connected to the same Oracle backend DB I assume. That has to be the case
for your scenario to work at all.
I don't know what you mean by the third storage node not in first cluster (A and B) -
as I understand it, all the RHQ storage nodes must be clustered together. I don't know
if you can have storage nodes in separate clusters (A and B in one cluster, C in its own
cluster). That just doesn't seem like it would work.
Go in your Administration>Agents page and look at your agent's failover list (shows
the list of all the servers it will try to connect to when it needs to failover). It
should show all 3. Or, you can go in your agent's data/ directory and look in the
failover.dat file - that's the list of the server endpoints it will try when it needs
to failover. Again, all three servers should be in there.
As for the F5 URL stuff, never tried it, don't know how it would work in an RHQ
environment. don't know anyone else that tried it either. maybe someone on the list
here can chime in if they know.

We currently have the following configuration for our RHQ server:
Production RHQ Server 1 (Node A)
Production RHQ Server 2 (Node B)
* Both nodes connected to the Oracle backend database)
* Storage nodes on each instance, clustered
BCP RHQ Server (Node C – different location)
* Storage node not in cluster
We have an F5 URL that sits infront of all the nodes, and can point to any of
them in the following scenario:
* Prod Node A fails, traffic directed to Prod Node B
* Prod Node A and B fails, traffic directed to BCP Node C
When an RHQ agent on a client windows box is configured, and the F5 GTM URL
is used as the RHQ Server, the agent connects to Prod Node A (as that node
is the primary active node for the F5 to point to). If I bring down both
Prod Nodes, I would think the F5 URL would connect the agent to the BCP Node
C RHQ server. But, it never connects to BCP, but rather in its logs shows it
trying to connect to both Prod nodes and failing. Is this due to the storage
nodes in Prod being clustered (assumption)? Why wouldn’t the F5 URL direct
the agent to connect to BCP?
