  NAME

    jbstart - Initializes the Jukebox Manager

  SYNOPSIS

    /usr/bin/jbstart [COLD | WARM] [config_file]

  DESCRIPTION

    The jbstart command initializes the Jukebox Manager (JBM).  Normally,
    jbstart does not need to be used.  A shell script starts JBM automatically
    at system startup.  This script is installed when the product is
    delivered.

    The JBM can perform a COLD or a WARM start.  The start mode can either be
    specified on the command line, or the jbstart command prompts the user for
    the type of start to be performed.  For a COLD start, JBM has no knowledge
    of the jukebox contents and performs a full inventory, reading the labels
    of all cartridges in the jukebox.

    A WARM start requires less time than a COLD start because it does not
    perform a full inventory on the jukebox.  The JBM records the jukebox's
    state on a magnetic disk when JBM is shut down.  When JBM is started, it
    knows whether it was shut down properly.  If it is shut down correctly, a
    WARM start consisting only of reading the magnetic disk record of the
    inventory is sufficient.  If JBM is not shut down correctly, a COLD start
    is needed.

    A HOT start automatically defaults to a WARM start.

    The configuration of the jukebox(es) is specified in the config_file
    configuration file.  This can either be specified on the command line, or
    the jbstart command prompts the user for a configuration file.  A default
    configuration file, /usr/ip32/jbm/JBCFG, is used if the user specifies a
    null string ( "" ) instead of a filename.

  EXAMPLES

    1.  To prompt the user for the start mode and the configuration filename,
        key in the following command:

        jbstart


    2.  To start JBM in COLD mode and prompt the user to specify a
        configuration file, key in the following command:

        jbstart COLD

    3.  To start the JBM in WARM mode, using the default configuration file,
        key in the following command:

        jbstart WARM " "


    4.  To initialize the JBM in WARM mode and use new.JBCFG as the
        configuration file, key in the following command:

        jbstart WARM new.JBCFG


  FILES

    /usr/ip32/jbm/JBCFG

  NOTES

    The jbstart command requires superuser privileges.

    The jbstart command prompts for the JBM configuration file if a second
    argument is not specified on the command line.  If a file is not supplied,
    /usr/ip32/jbm/JBCFG is used.  This file contains the following:

    ⊕  Logical names for the jukeboxes and their optical drives.

    ⊕  Terminal devices to which the jukebox robotics are connected.

    ⊕  Generic Small Computer System Interface (SCSI) character devices to
       which optical drives are connected.

    ⊕  Optional modes within which JBM can operate.

  CAUTIONS

    A COLD start process can require over an hour for a full jukebox.

  EXIT VALUES

    Exit values are not valid for the jbstart command.
