Rebuilding the HP-UX Operating System

Rebuild the operating system in the event of a disaster.

Before you begin

  • Ensure that the destination client is same as source client while performing a disaster recovery.
  • Make sure to install the Operating System exactly as it existed prior to a hardware or software corruption problem.
  • The client computer must have a default install partition with the HP-UX File System Agent installed on it. Make sure to enable the Networking option. The TCP/IP, hostname, and domain name settings of the default install must match those of the system that you are restoring.
  • A standalone tape device needs to be attached to the HP-UX computer to save the HP-UX File System Agent software and other processing software.
  • Use Hewlett Packard's Ignite-UX make_recovery utility software to restore HP-UX file system. This software is available free of charge at https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=IGNITEUXB. This software ensures that the appropriate HP-UX File System iDataAgent software configuration is preserved which eliminates the need to mount file systems that have been lost. This software also handles potential problems with the Volume Manager associated with HP-UX systems (e.g., decreasing file space).
  • Install the HP-UX File System iDataAgent software within the Root Volume Group to facilitate HP-UX restores.

Procedure

  1. Download Hewlett Packard's Ignite-UX make_recovery utility software and install it on HP-UX computer. Be sure to follow the instructions provided at Hewlett Packard's web site.
  2. Install the HP-UX File System iDataAgent software within the Root Volume Group.
  3. Edit the /var/opt/ignite/recovery/makrec.append file to include the directory where the HP-UX File System iDataAgent was installed.
  4. Type the appropriate command to execute a proper make_recovery utility per your system's processor.

    If your system has an Itanium processor, issue the following command:

    make_tape_recovery -va <tape device>

    If your system has a processor other than an Itanium processor, issue the following command:

    make_recovery -Cv -d <tape device>

    This command transfers the HP-UX File System iDataAgent software and the other required processing software to the "make_recovery" tape. 

    For example:

    make_tape_recovery -va /dev/rmt/0mn

    For example:

    make_recovery -Cv -d /dev/rmt/0mn

  5. Turn the computer on and use the maintenance menus to place the "make_recovery" tape into the bootable tape drive and boot from the tape.
  6. Select N to put your system in interactive mode.
  7. Exit and Restart your computer. Your HP-UX computer will now be restored with HP-UX File System.
