ADSM and 3494 Tape Library start and stop procedure

 KeyWords:      3494, library, ADSM
 Environment:   3494 Library attached to an ADSM v3 server
 Questions:     1. The 3494 Operator Guide says to ensure that all devices
                are varied offline to the appropriate host for power off.
                How do I vary drives offline "to the appropriate host"?
                2.  Same question as \#1 above, only power on 3494 and
                varyon devices.
                3.  Will the power off/on stop/start the OS/2 library
                manager?

                pages 67-68.

 Response:      By "vary off" this means make sure the drives are not in
                use and that they will not be accessed while the library
                is down.  I will give you ADSM commands below for this
                process.  As for the OS/2 console, It will be powered
                down as well.

START ADSM SERVER:
  /usr/lpp/adsmserv/bin/dsmserv
*OR*
  /usr/lpp/adsmserv/bin/rc.adsmserv
If not started in the background, you may press enter to acquire an ADSM
 command prompt.  Note, do NOT break out (\^C) or kill -9 ADSM Server except
 as a LAST resort.  Always attempt to issue the HALT command first, and
 wait for all processes and sessions to die off.

RUN ADSM COMMAND FROM SCRIPT:
  dsmadmc -id $user -pass $passwd "cmd opt opt opt"

OPEN AN ADSM COMMAND SESSION (SHELL)
  dsmadmc
This will ask for both a username and a password to ADSM, then will
 drop you at an ADSM command prompt.

  define drive $libname $drivename device=/dev/$devname

DISABLE ADSM DRIVE - adsm v3.x only
  update drive $libname $drvname online=no

REMOVE ADSM DRIVE:
