We have been using SRM for about 6 months now, all has been working fine.
Logged in this morning to run a test failover and the protection groups and recovery plans are missing.
Any ideas what has happen nad how to get them back
It looks like only vSphere Replication is running and connected.
Try shutdown the SRM appliance, and boot it up again...
Make sure you do this on both sites.
They should show up about 1-5 mins after the SRM appliances are powered on.
