SRDF Adapter for VMware Site Recovery Manager: SRA test failover failed with error "Failed to create snapshots of replica devices"

Errors from the SRA log: 

[ERROR]: The Symm Dev [XXXXX] on Symm [000XXXXXXXX] has consistency disabled. The adapter strongly recommends to enable consistency across the input RDF devices unless the devices belong to a single RA group and are synchronous 

[ERROR]: The Symm Dev [XXXXX] on Symm [000XXXXXXXX] has consistency disabled. The adapter strongly recommends to enable consistency across the input RDF devices unless the devices belong to a single RA group and are synchronous

The devices in question (highlighted in the above error) are part of Synchronous replication and NOT Asynchronous replication.

Though the devices in question are not part of asynchronous replication, the error indicates consistency. This is because the protection group contained devices that are part of multiple RDF groups, and the devices were not grouped. 

There are two options:

1. Add all devices to one RDF group.
2. Group all devices (from multiple RDF groups) in a composite group.

If the protection group contains devices from multiple RDF groups, then all the devices must be grouped in a composite group.

The recommendation and best practice is to have devices from one RDF group in one protection group.
