Overview

ViPR System and Tenant Administrators can learn about the steps to add a host to ViPR, the steps to configure the host initiators, and the optional steps to add the host to a cluster.

This article describes how you can add hosts, other than a Windows or Linux host, to ViPR. For instructions to add Windows or Linux hosts to ViPR, see the following two articles.

This article applies to EMC ViPR 2.0.

This article is part of a series

You can add hosts to ViPR at anytime. If however, you are setting up the ViPR Controller virtual data center for the first time, complete the following steps.
  1. Add physical assets to ViPR:
  2. Create ViPR virtual assets:
    1. Create and configure a virtual array
    2. Create virtual pools:

Add Hosts to ViPR

Before you begin

  • Hosts can be added to ViPR by ViPR System Administrators, and Tenant Administrators.
  • The HP-UX Operating System type sets the Volume Set Addressing (VSA) flag, which is required for exporting EMC VMAX volumes to HP-UX hosts.

Procedure

  1. Select Physical Assets > Hosts.
  2. If working in a multi-tenancy environment, select the Tenant.
  3. Add a host.
  4. Select Other, or > HPUX as the > Operating System type.
    HP-UX is only required if the host will be attached to EMC VMAX volumes.
  5. Enter a Name to identify the host in ViPR.
  6. Enter the Host fully qualified domain name or IP address.
  7. Save.

After you finish

The Host Initiators must be manually registered in ViPR before the host can be used in a provisioning operation.

Network configuration requirements for hosts

After a host is added to ViPR, configure the networks as required before using the host in a service.

Fibre Channel

When hosts are manually added to ViPR the host initiators must be manually added and registered to ViPR. For details see:

IP

Add host ports to IP network

The host IP ports must be manually added to the IP networks created in ViPR. Add the host, and storage system ports, which will be provisioned together, to the same IP network.

iSCSI

Hosts that use ViPR services with the iSCSI protocol must have their iSCSI ports logged into the correct target array ports before they can be used in the service.

Adding host initiators

Host initiators must be manually added for hosts that are not automatically discovered by ViPR.

Procedure

  5. Click Add.

After you finish

After adding the host initiators, they must be registered before they are available for use in ViPR service operations.

Add host ports to an IP network

If adding hosts to provision over an IP network, the host ports must be added to the IP network.

Before you begin

IP Networks are created by System Administrators. Tenant Administrators cannot configure IP networks or add host ports to the network.

Procedure

  1. Select Physical Assets > Networks page.
  2. If the Network is already created, click the name from the list of networks.
    If the Network is not created, create it:
    1. Click Add IP Network.
    2. Enter the network Name.
    3. Select the storage systems to include in the network.

Add the host to a cluster

Optionally, hosts can be added to ViPR clusters. Adding hosts to clusters allows service operations to be performed exclusively on a single host, or shared across all the hosts in a cluster.

Before you begin

  • Clusters can only contain the same type of hosts.
  • A host can only be used in one cluster.

Procedure

  1. Select Physical Assets > Clusters.
  2. If in a multi-tenancy environment, select the Tenant.
  3. If the cluster is not listed, create it:
    1. Click Add.
    2. Provide the Name, and click > Save.
  4. Locate the cluster that will be edited in the list of clusters.
  5. Click Edit Hosts in the right column in the same row as the cluster.
  6. Click Add.
  7. Check the box next to the host to add to the cluster, and click Add again.
