NOTE:

In HyperMetro (NAS) scenarios, only OceanStor V3 series V300R006C00 and later versions can be used to create protected groups for NAS file systems.

In HyperMetro (NAS) + HyperVault and HyperMetro (NAS) + asynchronous replication scenarios, when you create a protected group for NAS file systems, only the storage array of V3 series and V300R006C10 and later versions are supported.

For details about NAS file system compatibility, see the .OceanStor BCManager 6.5.0 eReplication Compatibility List.
