You must use SYSGEN to copy configuration groups. Using other methods to copy configuration files removes key elements and corrupts the files.

To copy a default configuration group into the configuration group CONFIG, follow the instructions outlined below:

  1. Activate SYSGEN.

    Entering SYSGEN activates SYSGEN's global module. 

    
  :SYSGEN

  SYSGEN version B.06.01 : catalog version B.06.02 FRI, MAY 20, 1988
  Copyright 1987 Hewlett-Packard Co.  All Rights Reserved

          **  First level command **

          io                log (lo)       misc (mi)        spu (sp)
          sysfile (sy)
          basegroup (ba)    keep (ke)      permyes (pe)     show (sh)
          tape (ta)

          clear (cl)(c)     exit (ex)(e)   help (he)(h)     oclose (oc)
          redo
  sysgen>

  2. Specify the base group on which to operate.

    Specify the group that more closely matches your system. Enter: 

    
  sysgen> BASEGROUP basegroupname

  3. Modify the configuration if necessary.

    If your system requires a configuration other than that provided by default, use the IO configurator to modify the current base group to meet your system's requirements. Refer to the chapter in this manual, that discusses the types of changes that you must make. After making any changes, hold them (issue the HOLD command in each configurator used to make changes), and return to SYSGEN's global module.

  4. Save the configuration to disk as CONFIG.

    After you have completed making changes, if any, save the configuration to the CONFIG group. Enter: 

    
  sysgen> KEEP CONFIG

  5. Generate a system load tape (SLT) if desired.

    To create an SLT that contains the new configuration, use CONFIG as the base group, and save it to tape, as discussed in Chapter 3 "System Startup Functions"

  6. Use the new configuration and restart the system.

    If you modified the configuration and now desire to implement it on the system, shut down and restart the system.

    To shut down the system enter: 

    
  :CTRL A

  =SHUTDOWN

  7. The system responds by listing shutdown messages: 

    
  Shutdown of operating system begins. (Shut 1)
  Shutdown of user processes begins. (Shut 2)
  Shutdown of jobs & sessions begins. (Shut 3)
  Spoolers notified of a shutdown. (Shut 16)
  13:11/39/Output spooler, LDEV #6:  Cannot open physical device.
  13:11/39/Output spooler, LDEV #6:  Stopped.
  13:11/38/The Spooling system has been shutdown.
  Shutdown of system processes begins. (Shut 4)
  Shutdown of operating system complete. (Shut 6)

  8. Reset the system using RS or TC. Restart it by specifying NORECOVERY. 

    
  ISL> START NORECOVERY

  9. Prepare the system for normal production.

    You may wish to check certain items to ensure that the system is ready for production. These items can include:

    • jobfence parameters

    • limit parameters

    • LAN status
