Accessing Enteprise Manager via Cluster Scan VIP

Question

Hello all...
We have a few clusters set up, and we've been accessing Enterprise Manager for these via the cluster scan IP address. For some unknown reason we now cannot access two of the three OEM installations via the scan IP, only by the IP address of the first node. Unfortunately I wasn't involved in this stage of the setup and I'm not having a lot of luck finding docs relevant to this.
The clusters are running 11.2.0.2 Standard with the January 2012 patch set, and the nodes in the clusters with the issue don't have any problem pinging each other or the scan URL for the custer, if that's helpful.
Can someone point me in the right direction?
Thanks,
Dan

Ravi,
DB Control was set up independently of the database using "emca".
The scan name in the emoms.properties file does match up with what's listed when running the "srvctl config scan" command.
When I attempt to connect to the scan address from Node2 using the following command, I get this response:

ERROR:

I have no problem tns pinging the scan name or the database name:
[oracle@devdb2 ~]$ tnsping devdb-scan.rp.db

Connecting using the following command directly to the TNS name for the database works too, so I'm a bit confused as to why specifying the scan name with port doesn't...
[oracle@devdb2 ~]$ sqlplus username/password@DEVDB
