Assigning a LUN Filter

Assigning a LUN filter involves the following steps:

Accessing the LUN Filter View

  1. Access the LUN Filter View by clicking the Filter View tab on the main window.
  2. Click the container symbol to expand the device trees and view the servers in detail on the left and the array devices in detail on the right.

Adding an HBA Device Manually

    If you do not see the desired HBA device under the Hosts displayed, you can add the HBA device manually through the Configure Host/WWN window.

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

  3. In the Available Hosts list, select the host that has the HBA device to be added, and click Edit. (If the host is under the Connected Hosts list, select the host and click Remove to place the host under the Available Hosts list.)

  4. In the Add/Edit Host box, click Add.
  5. In the next Add/Edit HBA box, enter the new Adapter Name and the appropriate WWN, and click OK.
  6. For details on determining the WWN, see Determining Host Worldwide Names, Worldwide Node Names, and Worldwide Port Names.

  7. In the Configure Host/WWN window, select the edited host, and click Add to move the edited host to the Connected Hosts lists.
  8. When you go to the LUN Filter view, the new HBA device is gray and is available for LUN filtering.

Removing Standard Mapping

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

  1. Click on each All Hosts item, and drag and drop it to Storage Pools.

    Click OK to the following message:

    Operation will delete all normal maps of Logical Drive X Partition X. Do you want to continue?

    A message confirming the successful deletion of the standard host LUN mapping is displayed.

  2. If the host is not the primary agent for a StorEdge device and you want to map the device to that host, select the device and select Configuration > Configure Host WWN.
  3. Highlight the desired host from the Available Hosts list, and click Add to add the host to the Connected Hosts.
  4. A message is displayed to confirm the addition of the host server.

  5. Click Close to save the configuration information and exit the window.
  6. If you want to map multiple hosts to an array , select Configuration > LUN Filter Properties, and then select the array from the pulldown menu.
  7. Select the Hardware Filter and Map to Multiple Hosts check boxes, and click OK.
  8. NOTE: If you uncheck the Hardware Filter check box, you cannot create a filter mapping; you can only create a standard map.

To Map Logical Drives to Hosts

  1. Make sure you are still in the LUN Filter view; if not, click the Filter View tab.


  2. Select a logical drive from Storage Pools, and drag and drop it to the appropriate HBA card under Hosts.
  3. If the HBA card connected to the array is not known, drag and drop the logical drive to the host. The program prompts you to filter the array for each HBA card in the host (which means that it is visible to the HBA card attached to it and does not appear for the other HBA cards).

  4. When the prompt is displayed to confirm the mapping, click OK.

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


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

    The assignment of the primary controller or secondary controller to an HBA card 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 Step 6 under Adding HBA Devices Manually.

    A warning prompt is displayed informing you that two users accessing the same logical drive at the same time may cause data corruption; click OK to add the additional host.
