  The hostname of the proxy computer and the client computer should be visible on the Device Manager Server.

• Appropriate licenses for Shadow Image and COW snapshot.
• For VSP, USP, USP-V and AMS 2000 series, create the following to allow COW operations:
  • COW pools

• For HUS, ensure that the source and target devices have the same Provisioning Attribute selected. For e.g., if the source is Full Capacity Mode then the target device should also be labeled as Full Capacity Mode.

Additional Requirements for VMware

When performing SnapProtect operations on VMware using HDS as the storage array, ensure the following:

• HDS LUNs are exposed to the Virtual Server iDataAgent client and ESX server.

• All HDS pre-requisites are installed and configured on the Virtual Server iDataAgent client computer.

• The Virtual Server client computer is the physical server.

• The Virtual Machine HotAdd feature is not supported.

Setup the Array Information

Provide the identification information for the array to ensure access. The following section provides step-by-step instructions for setting the array information.

1.	From the CommCell Console, navigate to Tools | Control Panel. Click Array Management.
2.	Click Add.
3.	Select HDS from the Snap Vendor list. Specify the serial number of the array in the Name field.
	For reference purposes, the screenshot on the right shows the serial number for the HDS storage device.
4.	Enter the IP address or host name of the Device Manager Server in the Control Host field. Enter the user access information in the Username and Password fields. In the Device Group field, specify the name of the hardware device group created on the array to be used for snapshot operations. The device group should have the following naming convention: <COW_POOL_ID>-<LABEL> or <LABEL>-<COW_POOL_ID> where <COW_POOL_ID> (for COW job) should be a number. This parameter is required. <LABEL> (for SI job) should not contain special characters, such as hyphens, and should not start with a number. This parameter is optional. Select the Use devices only from this device group option to use only the snapshots devices available in the device group specified above. Use the Description field to enter a description about the entity. This description can include information about the entity's content, cautionary notes, etc. Click OK to save the information.
