Configuring Physical Arrays and VSM Arrays for GAD in Array Management

For a (global-active device) GAD pair, you need to configure one physical array for each virtual storage machine (VSM) array in the GAD pair. The procedure to configure a physical array and a VSM array is similar and you need to repeat the procedure for each physical array and for each VSM array.

Before You Begin

  • You must configure the physical array and the virtual storage machine (VSM) array in the Hitachi Vantara console.
  • For a physical array, you must have the serial number of the physical array that is configured in the Hitachi Vantara console that you will use in the following procedure.


  1. On the ribbon in the CommCell Console, click the Storage tab, and then click Array Management.

    The Array Management dialog box appears.

  2. Click Add.

    The Array Properties dialog box appears.

  3. On the General tab, specify the following information:
    • From the Snap Vendor list, select Hitachi Vantara.
    • In the Name box, enter the name of the physical array or the VSM array. For the VSM array name, use the same VSM name that is configured in the Hitachi Vantara console. Prefix the array name with the number that corresponds to its model (for example, 312345 for G1000, or 455787 for G400).
    • The value in the Control Host box doesn't apply to Hitachi Vantara arrays. Thus, you don't need to enter a value.
    • In the Credentials area, click Change, and then enter the credentials for a user who has permissions to modify and to view the device manager that will access the array. If you are configuring a VSM, then these permissions are the same as the permissions for the physical storage array.
  4. On the Array Access Nodes tab, select the MediaAgents to use as array access nodes for the storage array:
    • To add an array access node, under Available Array Access Nodes, select one or more MediaAgents from the list, and then click Add.
    • To add all the MediaAgents as array access nodes, click Add All.
  5. On the Snap Configuration tab, specify the following information:
    • In the Physical array serial id (CCI engines) box, enter one of the following values:
      • For a physical array, enter nothing. For a physical array, the Physical array serial id (CCI engines) property must be empty.
      • For a VSM array, enter the serial ID of the physical array.
    • Clear the Disable GAD operations for the devices (CCI engines) check box.
  6. Click OK.
