Add cluster hosts to the storage array:

1. For each server to be added to the storage array, obtain the HBA’s WWNs.

You can view the HBA WWNs from the server’s iDRAC or ESXi shell:

• To view the WWNs from the iDRAC, log in to the iDRAC, expand Hardware, and then click Fibre Channel devices. Expand a device under Fibre Channel Ports to view the port’s WWN.
• To view the WWN from the ESXi shell, run the following command:

esxcli storage core adapter list

The port WWNs are displayed, as shown in the following figure:
