Validate EMC SMI-S Provider setup

Procedure

  1. Verify that your SMI-S Provider setup is valid.
    • The host server running Solutions Enabler (SYMAPI Server) and SMI-S Provider (ECOM) differs from the server where the VMAX service processors or VNX storage processors are running.
    • The VMAX/VNX array is discovered in the SMI-S Provider.
    • The remote host, SMI-S Provider (Solutions Enabler (SYMAPI Server) and EMC CIM Server (ECOM)) are configured to accept SSL connections.
    • The EMC storsrvd daemon is installed and running.
    • Ensure that SYMAPI Server and the ViPR server hosts are configured in the local DNS server and that their names are resolvable by each other, for proper communication between the two. If DNS is not used in the environment, be sure to use the hosts files for name resolution (/etc/hosts or c:/Windows/System32/drivers/etc/hosts).
    • The EMC CIM Server (ECOM) default user login, password expiration option is set to "Password never expires."
    • VNX connection is over the IP network with connections to both VNX storage processors.
    • For VNX, the SMI-S Provider host needs IP connectivity.
    • For VMAX, the SMI-S Provider host is able to see the gatekeepers (six minimum).

Preconfiguration requirements

Before adding VMAX or VNX for Block storage to ViPR, configure the storage, and storage provider as follows.

Create a sufficient amount of storage pools for storage provisioning with ViPR on both the VMAX and VNX for block storage systems.

VMAX storage systems

VNX for Block storage systems

SMI-S Provider

When the storage provider is added, all the storage systems managed by the storage provider will be added to ViPR. If you do not want all the storage systems on an SMI-S provider to be managed by ViPR, configure the SMI-S provider to only manage the storage systems that will be added to ViPR, before adding the SMI-S provider to ViPR.
Note Image
Storage systems that will not be used in ViPR, can also be deregistered, or deleted after the storage provider is added to ViPR.

Add storage provider

Adding the storage provider to ViPR adds the storage provider and all the storage associated with the storage provider to ViPR.

Before you begin

Only System Administrators can add storage providers to ViPR.

Procedure

  1. Select Physical Assets > Storage Providers.
  2. Click Add.
  3. Enter the storage provider Name.
  4. Select the storage provider Type.
  5. Enter the storage provider Host IP address.
  6. Enable or disable SSL.
  7. Leave the default or enter the Port.
  8. Enter credentials for the storage system. Storage system administrator privileges are required.
  9. Click Save.
    • The storage provider is displayed in the Storage Provider page.
    • Storage systems discovered with the storage provider are displayed in the Storage Systems page.

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 for block storage systems

After the storage system is added to ViPR, configure the SAN switches before adding the storage systems to a virtual array.

Fibre Channel

Add the corresponding SAN Switch from the ViPR Physical Assets > Fabric Manager page. When a SAN switch is added 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.

Refer to Add Fabric Managers and SAN Networks to EMC ViPR for more information.

iSCSI

For Storage Systems that use ViPR services with the iSCSI protocol, the iSCSI host ports must be logged into the correct target array ports before they can be used in the service.
