Adding a SAN Device Path

After you have defined a SAN device, specify the paths to that device. This informs DPX of all the nodes that can access that device.

To define a new SAN Device Path:

  1. Click Configure on the Function Tab bar of the window, then click Devices.

  2. Open the Add Device Path dialog in the right pane by doing one of the following:

    • Right-click the device name or icon to display a context menu. Then select Add Device Path. The selection is indicated by the selection check box next to the device icon.

    • In the left pane, select the SAN device to which you want to add the SAN device path and do one of the following:

      • From the menu bar, select Device > Add Device Path.

      • On the task panel, click Add Device Path.

    The Add SAN Device Path dialog appears.

  3. Complete the active fields in the Add Device Path dialog:

    • Device Path Name

      Enter or accept the default name for the path. This is the name that is used to access this device through the node and ID you specify in the next two fields.

      Note. On the Device Resource Tree, the SAN device path appears as device_path_name@logical_node_name.

    • Logical Node Name

      Select the name of a node from which the device can be accessed (for example, SALES_SERVER1). This node must have been previously defined (via the Configure Enterprise function).

    • Device ID

      • For devices on UNIX, Linux, or OES Linux, enter the path to the device file. For example, for Linux, the first storage device is usually /dev/nst0. For each additional device, the number in the path increments, thus your second device would be /dev/nst1.

        The following table lists common Device ID nomenclature for various flavors of UNIX:

        UNIX Type
        First Device ID

        Solaris

        /dev/sync_sa/t1d0

        Sun PC

        /dev/sync_sa/t1d0

        Linux

        /dev/nst0

        OES Linux

        /dev/nst0

        HP-UX

        /dev/rmt/c2t0d2BESTn

        AIX

        /dev/rmt0.smc

      Warning! Support for some of the documented operating systems may have been discontinued.

      • For devices on supported versions of Windows, the first device is normally called \\.\Tape0. For each additional device, the number in the ID increments (i.e., your second device is \\.\Tape1). You can find this information displayed in Tape Devices in the Control Panel of the Windows node. To do so, go to the Control Panel, select Tape Devices, choose the Properties tab, select the device, and click Properties. The Device ID is referred to as the Device Map.

    • Comment

      Enter an optional comment up to 48 characters.

  4. Select Add on the task menu at the top right of the right pane. If you are unable to see the task menu, resize the right pane.
