Using NPIV port for RDM disk access in VMware vSphere

Following are the steps to create NPIV port on an adapter (only tested with Brocade HBAs) on a host with VMware vSphere ESX/ESXi hypervisor:
Generate NPIV port(s) WWNs for VMUse the generated NPIV port WWN, the physical port WWN and the storage port WWN in one Zone (don’t put any other WWNs in the zone). There could be other zones in the final activezone config but the zone which is to let the vSphere create NPIV port should only have those 3 WWNs (physical port, NPIV port and storage port) Note: It is important to note that for RDM access through NPIV port to work we also need to have the base port in the zone. We cannot remove the base port from the zone after the NPIV port is created. Doing so results in making the RDM disk inaccessible.Confirm that the SAN storage is visible in the Host > Configuration > Storage under Devices. Power off the VM. Add a hard disk to the VM (VM > Edit Settings > Add > Hard Disk). Choose the option “Raw Device Mappings” to create an RD…
