ViPR 2.2 - Configure Registered Storage Systems Using the ViPR UI

Table of Contents

ViPR storage system configuration overview

ViPR System Administrators can learn to configure storage systems that have been added, discovered, and registered to ViPR.

ViPR role requirements

Only System Administrators can configure storage registered to ViPR.

Storage system discovery and registration

After a storage system is added to ViPR, ViPR automatically discovers, and registers the storage system, and storage system resources. There are optional configuration steps that can be performed on the storage system, and its resources, after the storage has been added, discovered, and registered in ViPR.

Steps to add storage systems to ViPR are provided in Add Storage Systems Using the ViPR UI.

Third-party block (OpenStack) storage port discovery

The OpenStack API does not provide the storage port World Wide Port Name (WWPN) for Fibre Channel connected storage systems, or the IQN for iSCSI connected storage systems. Therefore, ViPR cannot retrieve the storage port WWPNs, or IQNs during discovery. If any of the third-party block storage ports will be configured for Fibre Channel, you will need to add the WWPNs to the FC ports using the ViPR CLI. For complete details see: Configure Third-party Block Storage System Ports for ViPR.

Customize the Host Mode Option for HDS Storage

The Host Mode Options are a set of flags which can be enabled or disabled to further optimize the Host Mode set on the HDS host groups. You can customize the ViPR default Host Mode Options in the ViPR, Physical Assets > Controller Config page. The Host Mode Options are set on the HDS host group by ViPR when you use ViPR to export an ViPR volume to an AIX, ESX, HP-UX, Linux host.

For complete details see Set the Host Mode, and Host Mode Option for HDS Storage.

Deregister or delete a storage system from ViPR

Deregister a storage system to keep the storage system in ViPR, while not allowing ViPR to use any of the available storage resources. Delete a storage system to remove it completely from ViPR.

Block storage systems

Block storage systems are added to ViPR by adding the storage provider. When you add a storage provider to ViPR you add all the storage systems managed by the provider to ViPR. 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 a storage system

Before you begin

  • You cannot delete a storage system that has resources currently under ViPR management.
  • You can deregister a storage system that has resources currently under ViPR management. Once deregistered, the resources under ViPR management will remain under ViPR management, but no more of the storage system resources will be used by ViPR.

Procedure

  1. From theViPR UI, 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.

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. For block storage, specify the maximum number of volumes, for file storage specify the maximum number of file systems to allocate to ViPRfor provisioning on this storage system. The amount must be 0 or higher.
    The Resource Limit value is a count of the number of volumes, or file systems 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.

Note Image
This operation does not apply to VPLEX storage systems.

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 block volumes, or file systems that ViPR can provision from a storage group, and the maximum subscription percentage for thin pool provisioning.

Note Image
This operation does not apply to VPLEX storage systems.

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 block storage, thin pool provisioning, set a maximum snapshot percentage.
    The default is 300%.
  7. Enter a numeric value for the block volume, or file system limit available to ViPR to provision from this storage pool.
    By default, there is no limit on the amount of storage from a storage pool that can be used by ViPR.
    The Resource Limit value is a count of the number of block volumes, or file systems 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, and registers the storage system. To make storage ports unavailable to ViPR for provisioning, deregister them.

Note Image
This operation does not apply to third-party storage systems added through OpenStack.

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.
