Active–passive relationships in AFM DR

AFM DR creates an active–passive relationship between the primary and the secondary clusters.

Features

Only the primary can write to the secondary fileset. The secondary is read-only for all other users.
You can take a snapshot of the secondary fileset and use the secondary as a source to create backups or additional copies.

The secondary fileset is protected, so no other program or application other than the primary can write to the secondary.

All operations are allowed on the primary fileset, but only snapshot operations are allowed on the secondary fileset.
The secondary can be converted into the primary even when the primary is writing to the secondary. There is no protection against an administrator doing a failover operation on the secondary, even if the DR relationship is healthy.
The administrator must ensure that the primary cannot accidentally write to secondary after a failover.
