    See Appendix D for more information on drive arrays. See Chapter 5, “Running the Array Configuration Utility,” for information on configuring your drive arrays using the Compaq Array Configuration Utility. Fault Tolerance Fault tolerance refers to several possible methods used to protect data from being lost in the event of a hardware failure somewhere in the storage system.

  • Page 29: Updating The Firmware

    Updating the Firmware The ROMs on all Compaq servers and most Compaq options can be updated easily. This is done by flashing the ROM using a special Compaq utility called ROMPaq, which replaces the existing contents of the ROM with another version stored in a disk file.

  • Page 30: Materials Needed

  • Page 31: Running System Rompaq

    Running System ROMPaq System ROMPaq is used to update the firmware in Compaq servers. The SMART-2DH Controller has enhanced drive array capabilities; many existing servers may not be able to take advantage of these capabilities without updated firmware. Since it is difficult to determine when the firmware needs to be updated, Compaq recommends that you run the latest System ROMPaq on all servers when installing a new SMART-2DH Controller.

  • Page 32: Running Option Rompaq

  • Page 33 The latest version of firmware for the SMART-2DH Controller firmware has already been installed. If you have older SMART-2DH Controllers or other Compaq options, such as drives, create the Option ROMPaq diskettes and check that the firmware on these options is at the latest revision.
  • Page 34 8. When Option ROMPaq is finished reprogramming the SMART-2DH Controller ROM, press Enter if you wish to reprogram another Compaq option. Repeat steps 4 - 7. 9. If you are finished with reprogramming options, press Esc to exit the ROMPaq Utility.

  • Page 35: Running The System Configuration Utility

    The Compaq System Configuration Utility can be run directly from the Compaq SmartStart and Support Software CD supplied with the SMART-2DH Array Controller Option Kit and the Compaq server. You may already have a version of this utility in the system partition of the boot disk; however, you will need Compaq SmartStart and Support Software CD version 3.40 or later.
  • Page 36 If your server has a bootable CD-ROM drive, proceed to “Running the System Configuration Utility.” System Configuration Diskettes The latest version of the Compaq System Configuration Utility can be created from the Compaq SmartStart and Support Software CD that was supplied in the SMART-2DH Controller Option Kit.
