Prerequisites

Array Licenses

  • Virtual Copy license for 3PAR snapshot and 3PAR clone
  • Thin Provisioning (4096G) license for the Thin Provisioning option for cloning

Array Software

On HP3PAR, use one of these versions:

  • 2.3.1(MU4), 3.1.2(MU3), 3.1.3(MU1), 3.2.1(MU2), 3.2.1 (MU3), 3.2.2 , or 3.2.2.390 (EMU2)

On the client and proxy computers, configure:

  • The iSCSI Initiator to access the storage array

If virtual volumes are created using the 3PAR Management Console, ensure that a Common Provisioning Group (CPG) is selected for copy space. This space will store copies of all changes to the user data since the last snapshot of the volume.

Set Up the Array Information

The following section provides step-by-step instructions for setting up the array information.

  1. From the CommCell Browser, click the Storage tab and then click the Array Management icon.
  2. In the Array Management dialog box, click Add.
  1. Select HP 3PAR from the Snap Vendor list.

    In the Name box, specify the 16-digit number obtained from the device ID of a 3PAR volume.

    Follow the steps given below to calculate the array name for the 3PAR storage device:

    1. From the 3PAR Management console, click the Provisioning tab and navigate to the Virtual Volumes node.

      Click any volume in the Provisioning window.

    2. From the Virtual Volume Details section, click the Summary tab and write down the WWN number.

      This is the device ID of the selected volume.

      This WWN may be 8-Byte number (having 16 Hex digits) or 16 Byte number (having 32 Hex digits).

    3. Use the following formula to calculate the array name:
      1. For 8 Byte WWN (16 Hex digit WWN)

        2FF7000 + DevID.substr(4,3) + 00 + DevID.substr(12,4)

        where DevID.substr(4,3) is the next 3 digits after the fourth digit from the WWN number

        where DevID.substr(12,4) is the next 4 digits after the twelfth digit from the WWN number

        For example: if the WWN number is 50002AC0012B0B95 (see screenshot given below for 8 Byte WWN), using the following formula:

        2FF7000 + DevID.substr(4,3) + 00 + DevID.substr(12,4)

        DevID.substr(4,3) is 2AC  and DevID.substr(12,4) is 0B95

         After adding all the values, the resulting array name is 2FF70002AC000B95.

      2. For 16 Byte WWN (32 Hex digit WWN)

        2FF7000 + DevID.substr(4,3) + DevID.substr(26,6)

        where DevID.substr(4,3) is the next 3 digits after the fourth digit from the WWN number

        where DevID.substr(26,6) is the next 6 digits after the twenty sixth digit from the WWN number

        For example: if the WWN number is 60002AC5000000000000052200000B95 (see screenshot given below for 16 Byte WWN), using the following formula:

        2FF7000 + DevID.substr(4,3) + DevID.substr(26,6)

        DevID.substr(4,3) is 2AC and DevID.substr(26,6) is 000B95

        After adding all the values, the resulting array name is 2FF70002AC000B95.

  2. In the Control Host box, type the IP address of the array.

    Click Change and enter the access information of a user with administrative privileges in the Username and Password fields in Enter User Name and Password dialog box.

    The user must have Super or Edit User permissions.

    Use the Description field to enter a description about the entity. This description can include information about the entity's content, cautionary notes, etc.

  3. Click the Snap Configuration tab and configure the following:
    1. In the Storage Device Group, specify the name of the CPG group created on the array to be used for snapshot operations. If you do not specify a CPG group, the default CPG group will be used for snapshot operations.
    2. Select the Use devices only from this device group option to use only the snapshots devices available in the device group specified in the Storage Device Group field.
    3. Click OK to save the information.
