Creating a Virtual Input-Output Pool

You can create a virtual I/O pool that contains one or more virtual I/O identity types.

To create a pool of virtual I/O identity types:
  1. Click Deployment. The Deployment Portal is displayed.
  2. Perform one of the following:
    • On the left pane, under Common Tasks, click Create Virtual I/O Pool.
    • On the left pane, under Virtual I/O Pools , right-click Virtual I/O Pools > Create Virtual I/O Pool.
    The Create Virtual I/O Pool wizard is displayed.
  3. On the Name and Description page, type a unique name for the virtual I/O pool and an appropriate description, and then click Next.
  4. On the Ethernet Identities page, perform one of the following:
    • NOTE: If you do not want to include MAC addresses in the virtual I/O pool, clear the Include MAC addresses in this pool option, and then click Next.
    1. To specify the start address and the number of identities, perform the following:
      1. In the Specify the start address box, type the start address that you want to predefine in the MAC addresses that will be generated.

        • NOTE: The input address range (start address + number of identities) is validated against the existing address ranges for overlap when you are creating or editing a virtual I/O pool. The number of identities requested cannot be guaranteed in case the requested address range is overlapping with an existing virtual I/O pool address range.
      2. In the Number of Identities box, type the identity values that you want to define, and then click Next.

        • NOTE: For Converged Network Adapter (CNA) cards, WWNN and WWPN identities are derived from virtual FIP MAC address. In these scenarios, though the identities are not generated from the Ethernet Identities pool, these derived identities are counted against the Ethernet Identities pool. Ensure that necessary buffer is added while defining the Ethernet Identities pool size when virtual pool is used for deployment on servers with CNA cards.
    2. If you want to import the MAC addresses from a .csv file, click Import from file and perform the following:
      • NOTE: You can import up to 1000 identities using a .csv file. The .csv file must have a column titled Name or Value.
      1. Click Import.

      2. On the Import Wizard, click Import.

      3. Browse and select the .csv file and click Open. The Import Results window is displayed.

      4. Close the Import Results window and the Import Wizard, and then click Next.

  5. On the FCoE Node Name Identities page, perform one of the following:
    • NOTE: It is not necessary to have a virtual I/O pool with FC attributes for deploying on a Converged Network Adapter (CNA) card because the FC attributes are automatically generated by OpenManage Essentials based on the virtual FIP MAC address.
    • NOTE: If you do not want to include fibre channel WWNN identities in the virtual I/O pool, clear the Include Fibre Channel WWNN Identities in the pool option, and then click Next.
    1. To specify the start address for the WWNN identities and the number of identities to be generated, perform the following:
      1. In the Specify the start address box, type the start address that you want to predefine in the WWNN identities that will be generated.

        • NOTE: The input address range (start address + number of identities) is validated against the existing address ranges for overlap when you are creating or editing a virtual I/O pool. The number of identities requested cannot be guaranteed in case the requested address range is overlapping with an existing virtual I/O pool address range.
      2. In the Number of Identities box, type the identity values that you want to define, and then click Next.

    2. If you want to import the WWNN identities from a .csv file, click Import from file and perform the following:
      • NOTE: You can import up to 1000 identities using a .csv file. The .csv file must have a column titled Name or Value.
      1. Click Import.

      2. On the Import Wizard, click Import.

      3. Browse and select the .csv file and click Open. The Import Results window is displayed.

      4. Close the Import Results window and the Import Wizard, and then click Next.

  6. On the FCoE Port Name Identities page, perform one of the following:
    • NOTE: If you do not want to include fibre channel WWPN identities in the virtual I/O pool, clear the Include Fibre Channel WWPN Identities in the pool option, and then click Next.
    1. To specify the start address for the WWPN identities and the number of identities to be generated, perform the following:
      1. In the Specify the start address box, type the start address that you want to predefine in the WWPN identities that will be generated.

        • NOTE: The input address range (start address + number of identities) is validated against the existing address ranges for overlap when you are creating or editing a virtual I/O pool. The number of identities requested cannot be guaranteed in case the requested address range is overlapping with an existing virtual I/O pool address range.
      2. In the Number of Identities box, type the identity values that you want to define, and then click Next.

    2. If you want to import the WWPN identities from a .csv file, click Import from file and perform the following:
      • NOTE: You can import up to 1000 identities using a .csv file. The .csv file must have a column titled Name or Value.
      1. Click Import.

      2. On the Import Wizard, click Import.

      3. Browse and select the .csv file and click Open. The Import Results window is displayed.

      4. Close the Import Results window and the Import Wizard, and then click Next.

  7. On the iSCSI IQN Identities page, perform one of the following:
    • NOTE: If you do not want to include iSCSI IQN identities in the virtual I/O pool, clear the Include IQN Identities in the pool option, and then click Next.
    1. If you want to provide a prefix for the iSCSI IQN identities that will be generated, click Specify a prefix to allocate from , and type the IQN in the appropriate field.
      • NOTE: The typical iSCSI IQN format is: iqn.date.domainname-in-reverse:storage-identifier. For example, iqn.2001-04.com.example:storage.disk2.sys1.xyz.
      • NOTE: The iSCSI IQN identifier string can include the following special characters: hyphen, comma, colon, and period.
    2. If you want to import the iSCSI IQN identities from a .csv file, click Import from file and perform the following:
      • NOTE: You can import up to 1000 identities using a .csv file. The .csv file must have a column titled Name or Value.
      1. Click Import.

      2. On the Import Wizard, click Import.

      3. Browse and select the .csv file and click Open. The Import Results window is displayed.

      4. Close the Import Results window and the Import Wizard, and then click Next.

  8. On the Summary page, review the definitions with the number of identities that you provided for the I/O identity types, and then click Finish.
The virtual I/O pool that you created is displayed under Virtual I/O Pools on the left pane.
