ViPR 2.2 - Add Hosts and Clusters to ViPR

Table of Contents

Overview

ViPR 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 the steps to manually add, and register hosts to ViPR. When you add hosts to ViPR using the steps described in this article, you will also need to manually add and register the host initiators in ViPR.

To review the information about how to add a, AIX®, AIX VIO, Linux®, or Windows® host to ViPR, so that ViPR will automatically discover and register the host, and host initiators see the following articles:

You can add hosts to ViPR at anytime. If, however, you are setting up the virtual data center for the first time, complete the steps in Step by Step: Set Up a ViPR Virtual Data Center.

Add Hosts to ViPR

Hosts can only be added to ViPR by ViPR Tenant Administrators.

Before you begin

The following steps describe how to add a host to ViPR using the ViPR UI.

To use the REST API to add a host to ViPR see, Add Hosts and Clusters to ViPR Using the ViPR REST API.

Procedure

  1. Select Physical Assets > Hosts.
  2. If working in a multi-tenancy environment, select the tenant.
  3. Click Add.
  4. Select Other, or HPUX as the operating system type.
  5. Enter a name to identify the host in ViPR.
  6. Enter the host fully qualified domain name or IP address.
  7. Click Save.

After you finish

The Host Initiators must be manually registered in ViPR before the host can be used in a provisioning operation. See Adding host initiators for the steps to add the host initiators.

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

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.

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

  1. Open the Host Initiators page
    1. Select Physical Assets > Hosts.
    2. Locate the row for the host, and click the Initiators button in the Edit column.
  2. Click Add.
  3. If Fibre Channel, enter the host initiator Node (World Wide Name) name.
  4. Enter the Port information:
    • World Wide Port Name (WWPN) for Fibre Channel.
    • iSCSI Qualified Name (IQN) for iSCSI .
  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.

Back to Top

Registering host initiators

Host initiators manually added to ViPR or host initiators previously unregistered in ViPR, must be registered to be used in a service.

Procedure

  1. Open the Host Initiators page.
    1. Select Physical Assets > Hosts.
    2. Locate the row for the host, and click the Initiators button in the Edit column.
  2. Check the box in first column of the row or rows with the host initiators to register.
  3. Click Register.

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.
  3. Under the IP Ports table, click the Add to enter the host IP ports.
  4. Enter the host ports to use in the IP network.
  5. Click Save.

Replace a host initiator of an undiscovered host after a ViPR export operation

If ViPR was used to export a volume to a host, which was added to ViPR as “Other,” or if the host was added as undiscoverable, use the following procedures to replace a host initiator with a different host initiator after the export operation:

Procedure

  1. In ViPR, add the host port, on which the host initiator resides, to the same network from which the host initiator is being replaced, so that ViPR will see the connectivity between the host and the storage after the swap is complete.
    This should be the host initiator which will replace the initiator in the export.
    1. Go to the Physical Assets > Networks page.
    2. Locate the network to which you are adding the host port.
    3. Click the network name.
    4. Click Add > Add Host Ports, at the bottom of the Fibre Channel Ports table.
    5. Add the host port on which the host initiator you are adding resides.
  2. Add the host initiator to the host in ViPR
  3. Register the host initiator in ViPR.
  4. Remove the host initiator, which will be replaced by the host initiator added in the previous steps, from ViPR.
    1. Locate the row for the host on which the host initiator is being removed.
    2. Click Initiator in the Edit column of the host row.
    3. Select the row for the host initiator being removed, and click Deregister.
    4. Click Delete to delete the host initiator from ViPR.
    ViPR automatically updates the host initiators in the export group after the add, and remove operations are detected in ViPR.
