I've got the same issue. SRA version 2.1 (the latest) works just fine. When I install the 2.2 version I'm unable to discover arrays. Invalid array ID.
When I uninstall 2.2 en install 2.1 it works just fine. In this case the array manager connections are allready in place. But rescan devices shows invalid array id
I'm using srm 5.0 and svc 6.4
Do you have any work arround yet?
