E The following was excerpted from an article posted to Info-VAX.  Note H that to use the DUA4xxx device with PCX, you should just use the command       $ ALLOCATE DUA4xxx PCX_DISK   D before running PCX.  Also note that you may not be able to just makeJ the second of the two drives available (with SET xxx HOST_ACCESS); I couldK only make the second drive available if I made the first available as well.  -mdm   ==============1 >From: CLAYTON@XRT.UPENN.EDU ("Clayton, Paul D.") I >Subject: Thoughts On Topics Concerning HSC Usage, Problems And Trivia... 7 >Message-ID: <8912040431.AA25467@remote.dccs.upenn.edu>  >Date: 4 Dec 89 03:33:00 GMT   [...] P The use of FAKDSK will not work for CRONIC versions beyond 3.70. The alternate  P method is to do the following steps to gain access to the HSC load media from a 6 VAX processor. The use of EXCHANGE is not needed here.  F At the HSC console, with the switch in the 'ENABLE' position do these * commands. The media must be write enabled.   ^C HSC>RUN SETSHO SETSHO>SET SERVER DISK/LOAD  SETSHO>ENABLE REBOOT SETSHO>EXIT   ; Question about whether a reboot can take place goes here...   M After the HSC reboots, enter a 'SHOW DISK' command at the 'HSC>' prompt. The  L load media devices will show up with a device name of 'D4nnn'. One for each J device. The next step makes them available to the VAX CI based processors.    HSC>SET DEVICE D4nnn HOST_ACCESS  O This can be done for both devices. Write protect the boot media for the HSC at  B this point, and remove them from the drives, either TU58 or RX33.   L Next you want TU58 cartridges or RX33 floppies (already formatted using the K RXFMT program) which are to have the new files copied to them. From any CI  6 node the following commands will copy files as needed.  G $SHO DEV DUA	(looking for a DUA4nnn device name which are load devices) A $MOUNT/FOREIGN DUA4nnn	(where nnn is from the above SHOW command) / $COPY/WRITE_CHECK file_name.extension  DUA4nnn:  .  .  .  $DISMOUNT DUA4nnn:  N The device name may be prefixed with a HSC name such as HSC000$DUA4nnn:. Once N the copies are made and depending on what you copied, you can then procede to N configure the new tapes as needed. The HSC devices will remain defined within H the HSC using this procedure, even after a HSC reboot. You WILL have to N reenter the 'SET DEVICE xxx HOST_ACCESS' command when you need to gain access 7 again. This does not require a system reboot this time.    [...]    Paul D.
