Using fx to Restore the Swap Partition

Using fx to Restore the Swap Partition

The following procedure is an example of a use of the fx command. The procedure shown corrects the condition described in "Other Errors Loading the Miniroot", in which you receive the error message root and swap are on the same partition. In this procedure, the boot information is modified to cause you to boot from partition 0 (the root partition) instead of partition 1 (the swap partition) where the miniroot currently resides. (This discussion assumes that the 4D1-4.0 or later version of fx is used.)

Caution: The fx command is intended for advanced users and should not be used unless you have a definite need for it. Refer to the fx(1) reference page for for complete information on using fx.

Enter the command monitor (see "Preliminary PROM Monitor Procedure" for details on how to enter the command monitor on your system).
Invoke fx from the standalone version on your workstation, or from a local or remote CD-ROM. See the fx(1M) reference page for complete instructions on invoking fx, or use the following procedure.
- To invoke the standalone copy of fx on your workstation, enter
  >> boot stand/fx --x
- To invoke fx from a CD with installation tools in a CD-ROM drive on your workstation, enter the appropriate command.
  If your CPU type (cpu) is IP4, IP5, or IP6, the command is
  
  >> boot -f dksc(cntlr,unit,8)sash.cpu dksc(cntlr,unit,7)stand/fx.cpu --x
  If your CPU type is IP7 or IP9, the command is
  
  >> boot -f dksc(cntlr,unit,8)sash.cpu dksc(cntlr,unit,7)stand/fx.IP5 --x
  If your CPU type is IP12 or IP17, the command is
  
  >> boot -f dksc(cntlr,unit,8)sashcpu dksc(cntlr,unit,7)stand/fx.cpu --x
  If your CPU type is IP19, IP20, or IP22, the command is
  
  >> boot -f dksc(cntlr,unit,8)sashARCS dksc(cntlr,unit,7)stand/fx.ARCS --x
  In the previous command, cntlr and unit are the controller and unit numbers of the CD-ROM drive (see "Getting CD-ROM Device Numbers").
- To invoke fx from a CD with installation tools that is mounted on an installation server named server, enter the appropriate command.
  If your CPU is IP4, IP5, IP6, IP12, or IP17, the command is
  
  >> boot -f bootp()server:CDdir/stand/fx.cpu --x
  If your CPU type is IP7 or IP9, the command is
  
  >> boot -f bootp()server:CDdir/stand/fx.IP5 --x
  If your CPU type is IP19, IP20, or IP22, the command is
  
  >> boot -f bootp()server:CDdir/stand/fx.ARCS --x
  In the previous command, CDdir is the mount point directory for the CD (for example, /CDROM) and cpu is the CPU type of your workstation.
After fx is invoked, messages, prompts, and menus appear. A sample session is shown below. In this sample session, the default system disk device name, controller number, and drive number chosen by fx (dksc, 0, and 1 respectively) are used. Unless your workstation is configured in a non-standard way, the defaults chosen by fx will be correct and you can respond with <Enter> to the prompts.

At this point the System Maintenance menu appears, and you can restart your system or restart the installation.
