I know you can have multiple primary sites go to a single DR site. Can you do it the other way around? I need to make my primary site replicate to two DR sites. Is that possible? I setup the first primary to DR site okay. When I was installing the second SRM at my primary site, but I got a message during the install of the second SRM "vCenter Server %servername% already has a registered extension for VMWare vCenter Site Recovery Manger. Are you sure you want to ovewrite the exsisting registration?"
Is this configuration even possible?
I seriously doubt it's possible, have done shared recovery but never attempted your configuration...but, did you install using the documented custom setup procedure? Are you using a separate SRM database/DSN for each installation? At the point of installation, where it sounds like you're failing, SRM should not yet know which direction you intend to replicate...IIRC.
