Overview

ViPR System Administrators can learn about ViPR support requirements, prerequisite information to prepare Hitachi Data Systems (HDS) for ViPR integration, and the steps to add the storage to ViPR.

This article also describes how ViPR discovers, and registers the storage system after you add it to ViPR, and the optional configuration steps you can perform on the storage system after it is added and discovered in ViPR.

This article applies to EMC ViPR 2.0.

This article is part of a series

You can add storage systems to ViPR anytime. If however, you are adding physical and virtual assets to the ViPR Controller virtual data center for the first time, complete the following steps before attempting to run a service operation.
  1. Add physical assets to ViPR:
  2. Create ViPR virtual assets:
    1. Create and configure a virtual array
    2. Create virtual pools for block storage

Collect Hitachi HiCommand Device Manager information

Hitachi HiCommand Device Manager is required to use HDS storage with ViPR. You need to obtain the following information to configure and add the Hitachi HiCommand Device manager to ViPR.

Preconfiguration requirements

Before you add Hitachi Data Systems storage to ViPR, configure the storage as follows.

Add the Hitachi Data Systems storage to ViPR

Before you begin

  • Only System Administrators can add storage systems to ViPR.
  • You add the Hitachi HiCommand Device Manager to ViPR as a storage provider to enable ViPR to discover storage systems managed by HiCommand Device Manager. If you do not want all the storage systems on an storage provider to be managed by ViPR you can do either one or the following:
    • Before you add HiCommand Device Manager to ViPR, configure the HiCommand Device Manager with only the storage systems you want to add to ViPR. Move the storage systems that ViPR will not manage onto a different storage provider.
    • Or, after you add HiCommand Device Manager to ViPR, deregister or delete the storage systems that you do not want to be used as a ViPR resource.

Procedure

  1. Select Physical Assets > Storage Systems.
  2. Click Add.
  3. Select the Hitachi HiCommand storage system.
  4. Type the storage system name.
  5. Type the host IP address..
  6. Enable if the storage provider will use SSL.
  7. Leave the default or type the port.
  8. Enter user credentials with the HiCommand Device Manager. You need storage system administrator privileges.
  9. Click Save.
    • The Storage Provider page displays the HiCommand Device Manager.
    • The Storage Systems page displays the storage systems discovered with the storage provider.
    • A green check bock in the status row indicates that ViPR has successfully discovered the storage system.

Deregister or delete the storage systems that ViPR will not manage

When you add a storage provider to ViPR you add all the storage systems managed by the provider to ViPR. Once a storage system is added to ViPR it is automatically discovered and registered. Registered storage systems are available for ViPR to use and manage.

If you want ViPR to manage only some of the storage systems discovered with the storage provider, you can deregister or delete the storage system from ViPR.

Deregister or delete storage systems from ViPR

  1. In the Admin Mode, select Physical Assets > Storage Systems.
  2. Select the box in the storage system row.
  3. Click Deregister to keep the storage system in ViPR, and make it unavailable to use as a ViPR resource.

    Or, click Delete to remove the storage system from ViPR.

Storage system configuration

You can perform optional configuration steps on the storage system resources after the storage system is discovered in ViPR. The configuration steps are not available until the resources are discovered and registered in ViPR.

Once the storage system is discovered you can configure the following resources:

Define the storage system resource allocation limit

By default, storage systems are configured with unlimited resources that ViPR can use. You can set resource limits, which define the amount of storage in the storage system that is available for use by ViPR.

Procedure

  1. Select Physical Assets > Storage Systems.
  2. Click the storage system name in the Storage System table.
  3. In the Edit Storage System page, disable Unlimited Resource Allocation setting.
  4. Specify the maximum number of volumes ViPR is allocated for provisioning on this storage system. The amount must be 0 or higher.
    The Resource Limit value is a count of the number of volumes allowed to be provisioned on the storage system.
  5. Click Save.

Deregister storage pools

By default, all discovered storage pools are available for provisioning in ViPR. To make storage pools unavailable to ViPR for provisioning, deregister them.

If a storage pool becomes unavailable on the storage system, the storage pool remains in the list of available ViPR storage pools. You must deregister the storage pool manually in ViPR to ensure ViPR does not use it as a resource when a service operation is executed.

Procedure

  1. Select Physical Assets > Storage Systems.
  2. Locate the row for the storage system in which the pools reside.
  3. In the Edit row, click > Pools.
  4. Check the row for each pool that you want to make unavailable to ViPR for provisioning.
  5. Click Deregister.

Set the storage pool utilization limits

Storage pool utilization limits enable you to define the maximum amount of storage that ViPR can use from a storage pool, the maximum number of volumes that ViPR can provision from a storage group, and the maximum subscription percentage for thin pool provisioning.

Procedure

  1. Select Physical Assets > Storage Systems.
  2. Locate the row for the storage system where the pools reside.
  3. In the Edit row, click > Pools.
  4. Click the pool name.
  5. Change the Maximum Utilization percentage.
    The default is 75%.
  6. For thin pool provisioning, set a Maximum Subscription percentage.
    The default is 300%.
  7. Enter a numeric value for the Volume Limit available to ViPR to provision from this storage pool.
    By default, there is no limit on the amount of a storage pool that can be used by ViPR.
    The Resource Limit value is a count of the number of volumes allowed to be provisioned using the selected storage pool.
  8. Click Save.

Deregister storage ports

By default, all storage ports are available for provisioning in ViPR after ViPR discovers the storage system. To make storage ports unavailable to ViPR for provisioning, deregister them.

Procedure

  1. Select Physical Assets > Storage Systems.
  2. Locate the row for the storage system where the port resides.
  3. In the Edit row, click > Ports.
  4. Check the row for each port that you want to make unavailable to ViPR for provisioning.
  5. Click Deregister.

Network configuration requirements for storage

After you add the storage system to ViPR, add the corresponding SAN Switch from the ViPR Physical Assets > Fabric Manager page.

When you add a SAN switch to ViPR, the Fibre Channel networks (Brocade Fabrics or Cisco VSANs), are automatically discovered and registered in ViPR. Additionally, through discovery of the SAN switch topology, ViPR discovers and registers the host initiators for hosts on the network, and identifies which storage systems are associated with the SAN switch.

For more information, see Add Fabric Managers and SAN Networks to ViPR.
