Deployment Guide

2. On the Configure tab, select Storage Devices.

3. Perform a rescan of the storage devices.

4. Select the iSCSI disk (Dell EMC iSCSI disk) created in the Register the host and create and map volumes on page 54 procedure, then

select the Properties tab below the screen.

5. Scroll down to select the Edit Multipathing option, then select Round Robin (VMware) from the drop-down list.

6. Click OK.

7. Repeat steps 4–6 for all the volumes that are presented from the Dell EMC PowerVault ME4 Series storage system to the ESXi host.

Citrix XenServer hosts

Ensure that the HBAs or network adapters are installed and the latest supported BIOS is installed.

Fibre Channel host server configuration for Citrix

XenServer

The following sections describe how to configure Fibre Channel host servers running Citrix XenServer:

Prerequisites

• Complete the PowerVault Manager guided system and storage setup process.

• See the cabling diagrams within this guide before attaching a host to the storage system; careful planning ensures a successful

deployment.

• Install and configure the required version of the XenServer operating system on the hosts.

• Install XenCenter on a Windows computer, and connect it to the XenServer hosts.

• Configure the XenServer hosts into a pool.

Attach Fibre Channel hosts to the storage system

Perform the following steps to attach Fibre Channel (FC) hosts 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 EMC 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.

a. 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.

b. Repeat the previous step for each FC switch.

NOTE: The Dell EMC PowerVault ME4 Series storage systems support single initiator/multiple target zones.

Enable Multipathing on the XenServer hosts

Perform the following steps to enable Multipathing on the XenServer hosts using XenCenter:

1. Log in to XenCenter and select the XenServer host.

2. Right-click the host, and select Enter Maintenance Mode.

3. On the General tab, click Properties.

The Properties window is displayed.

4. Click the Multipathing tab, and select the Enable multipathing on this server checkbox.
