Restoring the engine hardware and operating system

This topic explains how to restore the hardware and the operating system for an engine.

Steps

  1. Verify that there is no damage to the hardware and that the engine boots properly. If you suspect a problem with any of the hardware components, troubleshoot an engine to resolve the problem.
  2. Verify that there is no damage to the master console and that it boots properly.
    1. If you suspect a problem with any of the hardware components in the master console, refer to your server documentation to resolve those problems.
    2. If you suspect a problem with the software or the hard disk drive, troubleshoot the master console to resolve the problem.
  3. From the master console, point the Web browser to the URL of the RSA II adapter on the engine and access the RSA II adapter to set up a remote console to the engine. This interface allows you to use the master console as your display and keyboard for the engine.
    Note: Instead of using the RSA II Web interface from the master console, you can directly attach a keyboard and display to the engine. However, make sure that you attach the display to the VGA port of the RSA II card on the engine and not to the video port on the engine itself.
  4. Determine if the boot drives for each engine hosting a metadata server still have an intact SAN File System configuration and executable files (undamaged).
  5. If there are corrupt or damaged configuration and executable files, attempt to recover the damaged files from the mirrored boot drive. If you cannot recover the damaged files from the mirrored boot drive:
    1. Load the Disaster Recovery CD into the CD-ROM drive on the engine.
    2. Reboot the engine using one of the following methods:
      1. Open a bash shell prompt and enter init 6.
      2. Press the Reset button on the front panel of the engine.
      3. Power off the engine and then power it back on.
    3. When you receive a warning prompt that the entire hard drive will be overwritten, respond by entering y.
    4. After the operating system has been reloaded, the engine will eject the Disaster Recovery CD and automatically reboot.
