Recovering Files with DISCUTIL 

DISCUTIL is a disk configuration utility that is called from the initial
system load prompt (ISL>).  Use it to configure disk devices and move
logically inoperable files from disk to tape.

The DISCUTIL SAVE command saves disk files to tape.  The volutil:
RECOVER command is then used to recreate and read the files from tape
back to disk.

Note that entering the ISL facility requires a system restart.  Send a
TELL or WARN message to your users that the system is going down.

Entering DISCUTIL 

Follow the steps below:

   1.  Reset the system with a soft reset.  At the system console, enter:

            :CTRL B 
            CM>TC 

   2.  Override Autoboot.  When the message TO OVERRIDE, PRESS ANY KEY
       WITHIN 10 SECONDS appears, press:

       Press any key.

   3.  Press Y to boot from the primary boot path when this prompt
       appears:

   4.  Press Y to interact with IPL when this prompt appears:
