Preparing the controllers for failover

Installation guidelines and restrictions  |  Preparing the controllers  |  Connecting the enclosure

Note: The cables to the drive enclosures must not be attached when you start the server.

  1. Insert the IBM ServeRAID Support CD (or the configuration CD that was included with your server) into the CD-ROM drive; then, turn on the server. The ServeRAID Manager program starts.

  2. If the ServeRAID Manager starts the Configuration wizard, a window similar to the following opens. Click Cancel to exit the Configuration wizard; then, in the confirmation window, click Yes.

  3. In the tree, click the ServeRAID controller that you want to configure as the active controller.

    Attention

    Restore the ServeRAID controller to factory-default settings only once, when the controller is first installed. This process removes all configuration information from NVRAM, including the SCSI initiator IDs, the controller and partner names, and the array information.

    This point is especially important if the Windows 2000 or Windows NT 4.0 system startup drive is attached to the IBM ServeRAID controller. If this process occurs after the startup-drive array has been created, the array information will be removed, and the system will no longer start in Windows 2000 or Windows NT 4.0.

    If you already have logical drives defined on the controller that you want to keep, go to step 6. Steps 4 and 5 will cause loss of data by deleting all logical drives already defined.


  4. Click Actions Restore to factory-default settings.

  5. If a confirmation window opens, click Yes. When the operation is complete, a message appears at the bottom of the window indicating that the ServeRAID Manager has successfully restored the configuration to the factory-default settings.

  6. In the tree, click the ServeRAID controller that you want to configure as the passive controller; then, repeat steps 4 through 5. Continue to step 7 for the second ServeRAID controller.

  7. In the tree, click the ServeRAID controller that you want to configure as the active controller.
  8. Click Configure for clustering icon (Configure for clustering) on the toolbar. The "Configure controller 1 for clustering" window opens.

  9. Provide the following information:

    Controller name
    Type a name to identify the first controller, for example, Controller A.

    Partner name
    Type a name that you will use to identify the second controller, for example, Controller B.

    Initiator IDs
    The system presets these SCSI initiator IDs to 7. Set each ID to 6 for shared channels. (The ServeRAID Manager program does not permit you to select numbers other than 6 and 7.)
    Notes:
    1. The controller name and partner name are case sensitive.

    2. If your configuration will contain multiple ServeRAID controller pairs, each controller name must be unique.
  10. Click OK.

  11. In the tree, click the ServeRAID controller that you want to configure as the passive controller.
  12. Click Configure for clustering icon (Configure for clustering) on the toolbar. The "Configure controller 2 for clustering" window opens.

  13. Provide the following information:

    Controller name
    Type the same name as the partner name in step 9, for example, Controller B.

    Partner name
    Type the same name as the controller name in step 9, for example, Controller A.

    Initiator IDs
    The system presets these SCSI initiator IDs to 7. When configuring the passive controller, do not change these values. (The ServeRAID Manager program does not permit you to select numbers other than 6 and 7.)
    Notes:
    1. The controller name and partner name are case sensitive.

    2. If your configuration will contain multiple ServeRAID controller pairs, each controller name must be unique.
  14. Click OK.
