Dell PowerVault ME5 Series Storage System Deployment Guide

Identify FC HBAs on a Linux server

Perform the following steps to identify the Fibre Channel HBAs on a Linux host.

1. Identify Fibre Channel WWNs to connect to the storage system by doing the following:
   1. Open a terminal session.
   2. Run the ls –l /sys/class/fc_host command.
   3. Run the more /sys/class/fc_host/host?/port_name command and replace the ? with the host numbers that are supplied in the data output.
   4. Record the WWN numeric name.
2. If the hosts are connected to the storage system using FC switches, implement zoning to isolate traffic for each HBA:
   NOTE Skip this step if hosts are directly connected to the storage system.
   1. Use the FC switch management interface to create a zone for each server HBA. Each zone must contain only one HBA WWN and all the storage port WWNs.
   2. Repeat for each FC switch.
      NOTE The ME5 Series storage systems support single initiator/multiple target zones.
