Configuring FC Host Mapping

You can configure the optional host mapping feature using the web client. This feature is disabled by default. For instructions about how to enable the feature, see Enabling/Disabling FC Host Mapping.

Depending on host operating system constraints, it might be necessary to reboot or reconfigure the host due to device mapping changes that result from configuring host mapping.

NOTE: This operation should not be performed concurrently by multiple administrative users logged in from different locations. You can access the appropriate screens, but you cannot apply changes while another administrative user is performing the same operation.

Users with administrative privileges can configure host mapping, but users with user privileges cannot.

  1. From the Setup menu, select I/O Blades > Host Mapping.

    The Setup - Blade Host Mapping screen appears. The screen lists the each host application's host name, I/O blade location, World Wide Port Name (WWPN), and operating system type. For more information about FC hosts, see Accessing an FC Host.

  2. NOTE: If an FC switch is attached to an I/O blade target port, the FC switch will appear in the Blade Host Mapping list as if it were a FC host. Do not map library devices to a FC switch. To avoid confusion, it is recommended that you modify the FC switch host name and type using Blade Host Management. See Modifying an FC Host Connection for more information.

  3. Select an FC host and click Next.

    The Setup - Blade Host Mapping screen appears. The screen lists the available partitions and tape drives connected to the I/O blade to which the FC host is attached. For each available partition and tape drive, the screen lists the following:

  4. Select the check box next to the partitions or tape drives you want to map.

    The text box under the LUN column is activated.

  5. In the LUN text box, type a new LUN number for the device.
  6. NOTE: A warning message displays if the command and control LUN (CCL) or another device is not mapped to LUN 0 (zero). LUN 0 is typically assigned to the command and control LUN (CCL), unless it has been manually mapped to another LUN. Make sure at least one device is mapped to LUN 0.

  7. Click Apply.
  8. The Progress Window appears. The Progress Window contains information on the action, elapsed time, and status of the requested operation.

  1. Save the library configuration.

    For instructions on how to save the library configuration, see Saving the Configuration.
