ONTAP software support and limitations for ASA r2 storage systems

While ASA r2 systems offers a wide range of support for SAN solutions, certain ONTAP software features are not supported.
-
Default automatic iSCSI LIF failover
In ASA r2 systems, the default networking LIF is shared between NVMe and SCSI hosts, so doesn't support automatic failover. To enable automatic iSCSI LIF failover, you must create an iSCSI only LIF. Automatic failover is enabled on iSCSI only LIFS by default.
When automatic iSCSI LIF failover is enabled, if a storage failover occurs, the iSCSI LIF is automatically migrated from its home node or port to its HA partner node or port and then back once the failover is complete. Or, if the port for an iSCSI LIF becomes unhealthy, the LIF is automatically migrated to a healthy port in its current home node and then back to its original port once the port is healthy again.

Support for SnapMirror replication
SnapMirror replication is supported on ASA r2 systems with the following limitations:
-
SnapMirror synchronous replication is not supported.
-
SnapMirror active sync is supported only between two ASA r2 systems.

-
SnapMirror asynchronous replication is supported only between two ASA r2 systems. SnapMirror asynchronous replication is not supported between an ASA r2 system and an ASA, AFF or FAS system or the cloud.
