Rules for sharing a target port with multiple FC initiator ports
Contributors Download PDF of this page
Connecting a maximum of two ONTAP FC initiator ports to a single target port on the storage array is supported. Each target port is zoned into two FC initiator ports, one from each cluster node. Sharing a target port connected to ONTAP systems with any other host is not supported.
Sharing a target port with multiple initiators helps in optimizing the use of storage array ports for connectivity with ONTAP systems.
The rules for this configuration are as follows:
When the ONTAP systems are in an HA pair, each node can share at the most one FC initiator port with the same target port.
All storage arrays must be from the same vendor and model family.
Connecting a single target port to multiple FC initiator ports is supported for MetroCluster configurations.
The best practice for zoning is to have each FC initiator-target port pair in a separate zone (1:1).
