Deployment Guide

Attach hosts to the storage system

Perform the following steps to attach Fibre Channel hosts 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 EMC 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:

a. Open a terminal session.

b. Run the ls –l /sys/class/fc_host command.

c. 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.

d. 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.

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 for each FC switch.

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

Perform the following steps to register the hosts, create volumes, and map volumes:

1. Log in to the PowerVault Manager.

2. Access the Host Setup wizard by doing one of the following:

• From the Welcome screen, click Host Setup.

• From the Home topic, click Action > Host Setup.

3. Confirm that you have met the listed prerequisites, then click Next.

4. Enter a hostname.

5. Using the information from step 3 of Attach hosts to the storage system on page 48 to identify the correct initiators, select the FC

initiators for the host you are configuring, then click Next.

6. Group hosts together with other hosts.

a. For cluster configurations, group hosts together so that all hosts within the group share the same storage.

• If this host is the first host in the cluster, select Create a new host group, then provide a name and click Next.

• If this host is being added to a host group that exists, select Add to existing host group. Select the group from the drop-

down list, then click Next.

b. For stand-alone hosts, select the Do not group this host option, then click Next.

7. On the Attach Volumes page, specify the name, size, and pool for each volume, and click Next.

To add a volume, click Add Row. To remove a volume, click Remove.

NOTE: Dell EMC recommends that you update the name with the hostname to better identify the volumes.

8. On the Summary page, review the host configuration settings, and click Configure Host.

If the host is successfully configured, a Success dialog box is displayed

9. Click Yes to return to the Introduction page of the wizard, or click No to close the wizard.

Enable and configure DM Multipath

Perform the following steps to enable and configure DM multipath:

NOTE:

Safeguard and blacklist internal server disk drives from multipath configuration files. These steps are meant as a

basic setup to enable DM Multipath to the storage system. It is assumed that DM Multipath packages are installed.

For RHEL 7 / SLES 12:

1. Run the multipath –t command to list the DM Multipath status.
