SnapProtect^™ Backup - EMC Symmetrix

Pre-Requisites

• EMC Solutions Enabler (6.4 or higher) installed on the client and proxy computers.

  Client Components (SYMCLI) are required only during the initial one-time configuration. Base Components (with SYMAPI) are necessary and required for all snap operations.

• SYMAPI Feature: BASE /Symmetrix licenses for Snap, Mirror and Clone.

  You can use the following command to check the licenses on the host computer:

  C:\SYMAPI\Config> type symapi_licenses.dat

• By default, all functionality is already enabled in the EMC Symmetrix hardware layer. However, a Hardware Configuration File (IMPL) must be enabled before using the array. Contact an EMC Representative to ensure TimeFinder and SRDF functionalities have been configured.

Setup the EMC Symmetrix

For SnapProtect to function appropriately, LUN Masking records/views must be visible from the host where the backup will take place:

• For DMX, the Masking and Mapping record for vcmdb must be accessible on the host executing the backup.
• For VMAX, the Masking view must be created for the host executing the backup.

Configure Symmetrix Gatekeepers

Gatekeepers need to be defined on all MediaAgents in order to allow the Symmetrix API to communicate with the array. Use the following command on each MediaAgent computer:

symgate define -sid <Symmetrix array ID>  dev <Symmetrix device name>

where <Symmetrix device name> is a numbered and un-formatted Symmetrix device (e.g., 00C) which has the MPIO policy set as FAILOVER in the MPIO properties of the gatekeeper device.

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 EMC Symmetrix from the Snap Vendor list. Specify the Symm ID of the array in the Name field.
	For reference purposes, the screenshot on the right shows the Symmetrix array ID (Symm ID) for the EMC Symmetrix storage device.
4.	If Symcfg Authorization is enabled on the Symmetrix Management Console, enter the access information for the Symmetrix Management Console in the Username and Password fields. In the Device Group field, specify the name of the device group created on the client and proxy computer. The use of Group Name Service (GNS) is supported. If you do not specify a device group, the default device group will be used for snapshot operations. 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.
