System Backup Commands 

The global command you use to make a system backup is TAPE (TA).

To create a system load tape, enter the following command:

     sysgen>TAPE Return 

 or

    sysgen>TA Return 

At the end of the backup, you will receive the message:

          ** Boot tape generated successfully **

If an error occurs during the backup, a flashing TAPE ERROR message is
issued to the Console, describing the error.

Creating a System Load Tape 

To create a system load tape that contains a new configuration, follow
the example commands:

          :SYSGEN ,NEWFIG

     SYSGEN version B.06.00 : catalog version B.06.00 THU, SEP 17, 1987,  3:01 PM
     Copyright 1987 Hewlett-Packard Co.  All Rights Reserved

             **warning** no NMCONFIG file in this configuration.
             **warning** NMCONFIG.PUB.SYSTEM is now the NMCONFIG fil

      ** First level command **

       io               log (lo)      misc (mi)      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>

(The text of the title may not be identical to that displayed above.)

Make your system configuration changes through the configurator
subsystems and save them temporarily with the >HOLD command.  For
information, refer to System Startup, Configuration and Shutdown 
Reference Manual (32650-90042).  Now return to the first-level SYSGEN
menu and keep the changes:

     sysgen>KEEP Return 

       or

     sysgen>KE Return 

     Keeping to group NEWFIG.SYS
     Purge old configuration (yes/no)?Y  ** Enter Y **
     sysgen>

To this point, your configuration changes have been saved to disk under
the configuration group NEWFIG. If you specify NEWFIG as the basegroup
and then issue the TAPE command, NEWFIG is written to tape as CONFIG.SYS.

     sysgen>BA NEWFIG
     sysgen>TA
     sysgen>EXIT
     END OF SUBSYSTEM
      :

SYSGEN will take about 15 minutes to store the new MPE XL system to tape
as CONFIG.SYS.

If you reboot the system from this tape, you will overwrite your current
configuration and it will be lost.  To avoid this, before rebooting,
recall the original CONFIG.SYS and store it under a different group name:

     sysgen>BASEGROUP CONFIG

       or

     sysgen>BA CONFIG

     sysgen>KEEP OLDCFIG  ** Keeping to group OLDCFIG **
     sysgen>

Reboot With the New Configuration 

To boot from the disk, enter:

     :CTRL B 
     CM>TC or CM>RS

       When the ISL> prompt is displayed, enter:

     ISL>START NORECOVERY GROUP=NEWFIG

If the system does not boot under the new group, you can use the START
GROUP=OLDFIG option under the Initial System Loader (ISL) to boot the
system under the original CONFIG group.  For more information on the
START command and options, refer to System Startup, Configuration and 
Shutdown Reference Manual (32650-90042).
