Dell PowerVault ME4 Series Storage System Deployment Guide

Attach a Linux host with FC HBAs to the storage system

Perform the following steps to attach the Linux host with Fibre Channel (FC) HBAs to the storage system:

1. Ensure that all HBAs have the latest supported firmware and driversas described on the Dell Support portal . For a list of supported standard FC HBAs, see the Dell PowerVault ME4 Seriesstorage Matrix on the Dell website. For OEMs, contact your hardware provider.
2. Use the FC cabling diagrams to cable the host servers either by using switches or attaching them directly to the storage system.
3. 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.
4. If the hosts are connected to the storage system by FC switches, implement zoning to isolate traffic for each HBA. 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.
