Datastore not validating from high availability server

[RebeccaRyan]

Having trouble validating DataStore from a high availability (dual machine) arcgis server, where the shared configuration is hosted on an FsX. This is ArcGIS 11.1

Am able to register/setup the datastore on its own instance to the server site, but not the other way around, all machines are joined to the same active domain and services are run using the domain account. I have checked permissions on the C:/arcgisdatastore (granted to the domain account), and security groups to get this working but still not able to validate the connection.

The connection property set was missing a required property or the property value was unrecognized. Server machine not found[ ]

Presuming you are talking about a Relational Data Store.
You say security groups are OK - are the Server Machines visible from the DataStore VM via https:6443?
And the Datastore machine open to the AGS machines over https:2443 and tcp:9876 ?
Also check, when you register the Datastore with the Server site, you should use the address of either of the AGS VMs - to the :6443/arcgis endpoint (not via the Load Balancer address)

The "connection property set" in error message is likely referring to 
<server_url>/<context>/admin/data/items/enterpriseDatabases/<AGSDataStore_ds_xxxxxx>/machines/<machine name>?f=pjson
This path leads to a json file that includes an adminURL which is the path to the :2443 endpoint for Data Store.
Validate that you can resolve this URL from both the Servers.

Thanks David,

it is as you suggested - requiring the https:6443 security group access on the DataStore VM from the servers.
