Add Fabric Managers and SAN Networks to ViPR

Overview

ViPR System Administrators can learn about ViPR support requirements, prerequisite information to prepare SAN (Brocade and Cisco) switches for ViPR integration, and the steps to add and configure the Fibre Channel (FC) networks in ViPR.

This article applies to EMC ViPR 2.0.

When you add a SAN switch to ViPR, ViPR discovers and registers Fibre Channel networks (Brocade Fabrics or Cisco VSANs). Through discovery of the SAN switch topology, ViPR can identify the hosts and storage systems connected through the same SAN switch. This allows ViPR to automatically build the connectivity between the hosts and storage systems when you run a provisioning service, such as "Creating a block volume for a host."

This article is part of a series

You can add Brocade and Cisco switches 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:

Fibre Channel switch (Fabric Manager) support

ViPR supports Brocade and Cisco switches that the following requirements:

Collect Brocade and Cisco switch information

To add Brocade fabrics, and Cisco switches to ViPR, you need the following information.

Record the following information for each Brocade EMC Connectrix Manager Converged Network Edition (CMCNE)

Record the following information for each Cisco swtich

Preconfiguration requirements and recommendations

Before you add SAN Switches to ViPR, you must configure the following.

Brocade CMCNE configuration requirements and recommendations

EMC Connectrix Manager Converged Network Edition (CMCNE) is installed, and configured as follows:
  • CMCNE can be downloaded from EMC Support Zone (https://support.emc.com). Refer to Fibre Channel switch (Fabric Manager) support for the CMCNE version support.
  • CMCNE must be installed on a different host than the storage system SMI-S provider. CMCNE uses the same port as the SMI-S provider, and therefore causes a port conflict if CMCNE and the SMI-S provider are installed on the same machine.
  • The SMI Agent (SMIA) must have been installed and started as part of the CMCNE installation. To validate if the SMIA is installed correctly:
    • Enter the CMCNE IP in a browser, and validate the SMI Agent (provider) is installed. CMCNE SMIA appears on the CMCNE Start page, if SMIA has been installed.

      If CMCNE SMIA does not appear in the start page if it was not installed with CMCNE.

    • If it is installed, and not functioning as expected, check the C:\<installation path>\cimom\server\logs\smia-provider.log file for any errors.
  • CMCNE must have access to the switches with administrator privileges.
  • Use the CMCNE UI to prediscover the fabrics.
  • You must have created the necessary fabrics that will be used by ViPR, assigned the ports to the fabrics, and configured any ISL links needed to connect a fabric between multiple switches.
  • It is highly recommended that you implement redundant connections among ISL connections, so that the failure of a single ISL link does not partition fabrics.
  • There is no restriction on the number of fabrics.
  • Zones do not need to be created.

Add Brocade and Cisco switches to ViPR

Only System Administrators can add Brocade and Cisco switches to ViPR.

Procedure

  1. Select Physical Assets > Fabric Managers.
  2. Click Add.
  3. Type a switch name.
  4. Select the type of switch.
  5. Depending on the type you select, provide the following information:
    Type Enter the following information:
    Brocade
    • SMI-S Host address
    • Enable/disable SSL
    • SMI-S Port
    • Credentials for an account that has administrator privileges to the SMI-S host
    Cisco
    • Host address for the switch
    • Port
    • Credentials for an account that has administrator privileges to the switch
  6. Click Save.
    ViPR discovers, and registers the fabric manager and the associated networks, and the Physical Assets> Networks page displays them.

Fibre Channel network configuration

After you add the switches to ViPR, ViPR discovers and registers the associated Fibre Channel (fabrics, and VSANs) networks and the Physical Assets > Networks page displays them.

Optionally, you can configure the FC networks according to the following procedures:

Deregister Fibre Channel Networks

Deregister the Fibre Channel networks (Brocade Fabrics, and Cisco VSANs) that will not be available to ViPR for use in a service.

  • Only System Administrators can deregister Fibre Channel networks.
  • When you add the associated Brocade or Cisco switchto ViPR from the Fabric Manager page, ViPR discovers, and registers the associated Fibre Channel networks.
  • You can deregiser, but not delete Fibre Channel networks in VIPR.

Procedure

  1. Select Physical Assets > Networks.
  2. To deregister a network in the list, select it.
  3. Click Deregister.

Assign storage ports and host ports to the Fibre Channel network

Add storage ports, and host ports to a Fibre Channel network (Brocade Fabrics and Cisco VSANs) to define the connectivity that ViPR uses when you provision storage to the hosts. When no one assigns ports to the Fibre Channel network, ViPR assigns the ports when the storage is provisioned to the hosts.

Before you begin

  • Only System Administrators can assign storage and host ports to Fibre Channel networks.
  • ViPR adds, discover, and registers, Fibre Channel networks when the associated Brocade or Cisco switch is added to ViPR from the Fabric Manager page.
  • You can define storage ports, or host ports, or both for the Fibre Channel network. ViPR uses whichever ports you have assigned to the network during provisioning. If you have not assigned ports, ViPR automates the assignment of ports to the network.

Procedure

  1. From the Admin mode, select Physical Assets > Networks.
  2. Click the network name to open the Edit Fibre Channel Network page.
  3. Add storage ports to the network. Click:
    • Add > Add Array Ports to select from the list of discovered array ports.
    • Add > Add Ports to enter the storage ports manually.
  4. Add host ports to the network. Click:
    • Add > Add Host Ports to select from the list of discovered host ports.
    • Add > Add Ports to enter the host ports manually.
  5. Click Save.
