    Setting up a host to use Unity VVol datastores

    Add the storage system as a VASA provider

    Add the system as a VASA provider in vSphere.
    Procedure
    1. In vSphere, go to Storage > Manage.
    2. Select Storage provider, then select the Add icon.
    3. Enter the Name of the storage system. It is recommended that you use the same system name as Unisphere.
    4. Enter the VASA provider URL for the Unity system. Use the following format: https://<management IP address>:8443/vasa/version.xml .
    5. Enter the Unisphere credentials and select OK.
    After you finish

    It may take a few minutes for the registration to complete.

    Configuring Unity File VVol datastores for the host

    Use the Unisphere UI or CLI to:

    Procedure
    1. Discover VMware ESXi hosts.
    2. Create capability profiles, NAS protocol endpoint servers (VVols-enabled NAS servers), and File VVol datastores.. You must create a VVol-enabled NAS server on each SP.
    After you finish

    For more information on performing these tasks, refer to the Unisphere online help or Unisphere CLI User Guide.

    Setting up the connection to a File VVol datastore

    Before you begin

    If the ESXi host cannot detect the storage system File VVol datastore, or if you are using generic host objects, you will need to manually set up the connection.

    Procedure
    1. Log into vSphere as an administrator.
    2. For each File VVol datastore:
      1. On the Inventory panel, select the host and click the Configuration tab.
      2. On the Hardware panel, click Storage, then Add Storage.
      3. Select Network File System as the file storage type.
      4. Enter the following information:
        • For folder, enter the path to the Unity share.
        • For name, enter the name of the new VMware datastore.
      5. Perform a rescan in vSphere to ensure that the VMware NFS datastore is now visible to the ESXi host.

    Add an iSCSI target for Block VVol datastores

    Add an iSCSI target in vSphere for SCSI Block VVol datastores.
    Procedure
    1. Under Hosts and Clusters, go to Manage > Storage.
    2. Under Storage Adapters, select the iSCSI Software Adapter.
    3. On the Targets tab, click Add.
    4. Enter the iSCSI details and click OK.

    Configuring the Unity Block VVol datastores for the host

    Procedure
    1. [For iSCSI only:] Add the software iSCSI adapter, if not already added, as described in VMware vSphere documentation.
    2. Use Unisphere UI or CLI to:
      1. Discover VMware ESXi hosts.
      2. Create Unity Block VVol datastores.
      For more information about completing these tasks, refer to the Unisphere online help or the Unisphere CLI User Guide.
    3. Rescan for the VMFS datastores:
      1. From the Hosts and Clusters panel, select the server.
      2. Select Manage.
      3. Under Storage, select Storage Adapters.

        For iSCSI:

        1. Select the iSCSI storage adapter in the list of adapters.
        2. Select the Rescan icon.

        For FC:

        1. Right click on the FC HBA and then click Rescan.
        2. In the Rescan dialog box, select the FC HBA, and then click Rescan.
      4. Under Storage, select Storage Devices.
      5. Select the Rescan icon.

      If the host can see the Block VVol datastore, you must set up the host to use the datastore, as described in the next section.

      If the host cannot see the Block VVol datastore, you may have one of the following issues.

      • iSCSI: A problem with the connection between the host and iSCSI target (iSCSI connection). Refer to iSCSI session troubleshooting for ESXi hosts for additional steps to resolve the problem.
      • FC: A problem with SAN connection between the host and the FC LUN (FC connection), in which case you need to manually configure this connection.
