barrif, when using EMC's SRDF Adapter (SRA), you have different requirements for testing a recovery plan and executing a recovery plan. With your current config (if it mirrors mine) you should be able to execute the recovery plan without any issues. But when you test it you get the errors mentioned above. For one, SRM SRA requires you to either manually edit the XML file or to install EMC's Virtual Storage Integrator. VSI adds new tabs on the host and VM views in vSphere client.
The XML file is located on the recovery SRM server at: “c:\program files\VMware\VMware vCenter
Site Recovery Manager\scripts\SAN\EMC Symmetrix\EmcSRDFraOptions.xml." I was not able to successfully edit this, but VSI and executing the recovery plan instead of testing it was good enough for my purposes.
Another problem with my configuration is VSI requires TimeFinder (Snap, Mirror, Clone, etc...) in order to do the local test without touching the production server.
Hope this helps.
