Assigning a LUN Filter

Assigning a LUN filter involves the following steps:

Accessing the LUN Filter View

  1. From the main window, click the Filter View tab.
  2. Click the container symbol to expand the device trees for detailed views of the servers (hosts) in the left pane and the array devices in the right pane.

Adding a New Host Manually

    If you do not see the desired host displayed in the left pane (under Hosts), add it manually through the Configure Host/WWN window.

  1. From the main window, click the Filter View tab.

  2. Choose Configuration > Configure Host/WWN.

    NOTE: If the Configure Host/WWN option is not enabled, select any one of the icons in the left pane to enable it.

  3. If you are not already logged in as ssconfig or ssadmin, a password prompt is displayed. Type the password and click OK.

    The Configure Host/WWN window is displayed.

  4. Under Available Hosts look for the host.

    If you see the host, go to Step 9.

    If you do not see the host, continue with Step 5.

  5. Under Available Hosts click Add.

    The Add/Edit Host window is displayed.

  6. Enter the host name, IP address, and the OS, and then click Add.

    The Add/Edit HBA window is displayed.

  7. Enter the new adapter name and the appropriate WWN, and then click OK.

    For details on determining the WWN, see Determining Host Worldwide Names, Worldwide Node Names, and Worldwide Port Names.

  8. Click OK to close the Add/Edit Host window.

  9. Under Available Hosts select the host, and click Add to add the host to the Connected Hosts list.

  10. Click OK to close the Configure Host/WWN window.

    A confirmation message is displayed.

  11. Click Close.

    When you return to the Filter View tab, the new host is available for LUN filtering.

  12. (Optional) If you want to map multiple hosts to an array, choose Configuration > LUN Filter Properties, and then select the array from the Select SANnet II Family System list box.

    Select the Hardware Filter and Map to Multiple Hosts check boxes, and then click OK.

    NOTE: If you uncheck the Hardware Filter check box, you cannot assign LUN filter mapping; you can only assign a standard map.

Adding an HBA Device Manually

    If you do not see the desired HBA device displayed in the left pane (under Hosts), add it manually through the Configure Host/WWN window. You can add up to 64 WWNs per array.

  1. Choose Configuration > Configure Host/WWN
  2. .

    NOTE: If the Configure Host/WWN option is not enabled, select any one of the icons in the left pane to enable it.

  3. If you are not already logged in as ssconfig or ssadmin, a password prompt is displayed. Type the password and click OK.

    The Configure Host/WWN window is displayed.

  4. Under Connected Hosts, select the host that you want to add an HBA device to, and click Remove.

  5. Under Available Hosts, select the host, and click Edit.

    The Add/Edit Host window is displayed.

  6. Click Add.
  7. The Add/Edit HBA window is displayed.

  8. Enter the new Adapter Name and the appropriate WWN, and click OK.
  9. For details on determining the WWN, see Determining Host Worldwide Names, Worldwide Node Names, and Worldwide Port Names.

  10. Click OK to close the Add/Edit Host window.

  11. Under Available Hosts, select the host, and click Add to move the host back to the Connected Hosts list.

  12. Click OK to close the Configure Host/WWN window.

    A confirmation message is displayed.

  13. Click Close.

    When you return to the Filter View tab, the new HBA device is gray, and it is available for LUN filtering.

Removing Standard Mapping

Before you can assign a LUN filter, you have to remove the standard host mapping (indicated by M labels [Mapped] Standard mapping label) from the array. Standard mapping enables all hosts to see all standard mapped logical drives. LUN filtering restricts the mapping to specific host(s).

Follow this procedure to remove standard host mapping:

  1. From the main window, click the Filter View tab.

  2. From the right pane, click each All Hosts item, and drag and drop it to Storage Pools.

    A warning message is displayed.


  3. Click Yes.

    A confirmation message is displayed.

  4. Click Close.

    When you return to the filter tab, note that the M label (Standard mapping label) has been removed from the logical drive.

Assigning a LUN Filter

After you remove the standard mapping, you are ready to assign a LUN filter by mapping logical drives to hosts.

  1. Select a logical drive under Storage Pools, and drag and drop it to the appropriate HBA device under Hosts.
  2. A warning message is displayed.

    NOTE: If the HBA device connected to the array is not known, drag and drop the logical drive to the host (server) in the left pane. The program prompts you to filter the array for each HBA device in the host. When this happens, the logical drive is visible to the HBA device on the host, but it is not visible (or accessible) to any other HBA device.

  3. Click Yes.

    The Specify Map Information window is displayed. Note that SANscape automatically maps the logical drive to the first HBA device listed in the host if there is more than one HBA device.

  4. Assign the logical drive to a primary or secondary controller and with the desired channels and LUN ID numbers, and then click OK.

    A confirmation message is displayed.

  5. Click Close.

    The assignment of the primary controller or secondary controller to an HBA device is selected for the initial LUN filter assignment, and cannot be changed unless you delete the LUN filter assignment and start over.

    To apply a LUN filter to a second host for one array, repeat the steps in Adding an HBA Device Manually and Assigning a LUN Filter.

    CAUTION: Because data corruption can occur, a warning message is displayed if two users access the same logical drive at the same time. This is a characteristic of some host OSs. Click Yes to add the additional host.

    An F (Filtered) (Filtered mapping label) label indicates that a LUN filter has been applied to the host.

Deleting a LUN Filter

  1. From the main window, click the Filter View tab.

  2. From the right pane, select the associated WWN, and drag and drop it to Storage Pools.

    A warning message is displayed.

  3. Click Yes.

    A confirmation message is displayed.

  4. Click Close.
