you are using the 8.1.02.xxx rscd agent that matches the appserver version you are using ? is there an existing PSI in the virtualization class for this server? if you try to add this via the blcli you might get a more details error message in the blcli.log.
We are using 220.127.116.11 of the rscd agent.
Using the blcli to add the server we get the following message java.lang.RuntimeException: null db key
There were some existing connectors for the PSI but when we try to remove it it says it's in use and would we like to mark it as deprecated.
I've added it to deprecated and it seems to have added in ok again. I need to run some tests for exploring the vm's and also provisioning but that seems to have fixed the problems.
