Dell PowerVault ME4 Series Storage System Deployment Guide

Attach a XenServer host with FC HBAs to the storage system

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

1. Ensure that all HBAs have the latest supported firmware and drivers as described on Dell.com/support. For a list of supported FC HBAs, see the Dell PowerVault ME4 Series Storage System Support Matrix.
2. Use the FC cabling diagrams to cable the hosts to the storage system either by using switches or connecting the hosts directly to the storage system.
3. Log in to the console for each XenServer host using SSH or XenCenter.
4. Use the following command to display and record the WWNs for the HBA ports that are connected to the storage system:

   systool -c fc_host -v | grep port_name

5. 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 the previous step for each FC switch.
