Controller Primary Agent Information - Out-of-Band Storage Management

The out-of-band storage management capability enables you to monitor and manage arrays over the network using TCP/IP. Unlike in-band storage management (the standard method of storage management), which requires the agent to be running on the server that is physically attached to the storage, out-of-band storage management does not require the agent to be running on the server that is physically attached to the storage. With out-of-band storage management, if the server that is attached to the storage is shut down, monitoring and maintenance is unaffected.

The following figures show examples of in-band and out-of-band storage management configurations:

Using Out-of-Band Management

NOTE: Controller, SAF-TE, SES, PLD, and drive firmware cannot be upgraded through out-of-band management.

NOTE: If you assign an IP address to an array to manage it out-of-band, for security reasons consider using an IP address on a private network rather than a publicly routable network. Using the controller firmware to set a password for the controller limits unauthorized access to the array. Changing the firmware’s Network Protocol Support settings can provide further security by disabling the ability to remotely connect to the array using individual protocols such as HTTP, HTTPS, telnet, FTP, and SSH. Refer to the “Communication Parameters” section of the SANnet II Family RAID Firmware User’s Guide for more information.
  1. Make sure you have set up a static or dynamic IP address for the array.

    If the program has been configured already to manage the array through in-band, you can set the IP address through Change Controller Parameters. To set the IP address, see the “Peripheral Tab.” If the program has not been configured yet, you can set the IP address through an RS-232 terminal. Refer to the SANnet II Installation, Operation, and Service Manual for your array.


  2. After setting the IP address, reset the controller.

    Choose Array Administration > Controller Maintenance, and then click Reset the Controller.

  3. Select the server.

  4. Choose View > Agent Options Management.
  5. Type the IP address of the array in the IP Address field, and click Add.

  6. If you have created a controller password for the array using the firmware application, type it in the Password field, and then re-type it in the Verify Password field.

    NOTE: By default there is no password set for the array. For information on creating or changing the controller password, refer to the SANnet II RAID Firmware User’s Guide for your array.

  7. Check Out-Of-Band Agent preferred over In-Band, and click OK.

    NOTE: With this option checked, out-of-band becomes the preferred method of storage management. If the out-of-band configuration is removed, the program reverts to in-band storage and monitoring after you start/restart the services.
  8. For SANscape to recognize the out-of-band array and display an out-of-band HBA icon in the main window, you need to send a Probe command to the server.

    Choose View > View Server, and then click Probe.

  9. If the program has not been configured to manage the array, you need to assign the server to manage the controller.

    Choose Array Administration > Controller Assignment. Select a server from the Server to manage this controller list and click Apply.

    An out-of-band HBA is displayed in the main window and View HBA Card is displayed in the Menu Bar under the View menu.

    NOTE: If an out-of-band HBA is not displayed in the window, reset the controller.

To Remove an Array From Out-of-Band Management

  1. Select the server.

  2. Choose View > Agent Options Management.

  3. Select the array's IP address that you want to remove, click Remove, and click OK.

    The HBA remains displayed in the main window; to remove it, you need to unassign and reassign the managing server.

  4. From the main window, choose Array Administration > Controller Assignment.

  5. Select the controller for which you want to unassign a server.

  6. From the Server to manage this controller list box, select none, and click Apply.

  7. Click Close to confirm.

  8. Reassign the managing server following the steps in Controller Assignment.
