The operating mode is set based on whether you have automation
software controlling cartridges in the ValueLoader or if you are manually
loading and unloading cartridges using the ValueLoader Operator's
Panel commands. The ValueLoader always operates in Autodetect Mode,
which is transparent to you. In Autodetect Mode, the ValueLoader
automatically assumes that you are not using an automation software
package to control cartridge or drive activity. This is called Stacker or
Sequential Mode. If the ValueLoader detects that an automation software
package is controlling tape/drive activity, it will automatically switch to
Random Mode.
Random Mode
This is the normal mode of operation when a backup software application
is being used. In Random Mode, the ValueLoader does not automatically
load tapes into the drive; instead, it waits for commands from the
software. To use Random Mode, you do not need to configure anything
from the ValueLoader front panel, but your backup software package
must support autoloaders, which often requires the additional
installation of a autoloader/library software module.
Sequential Mode
Sequential Mode is useful when an adequate software application is not
available. In Sequential Mode, the ValueLoader automatically loads and
unloads tapes from the drive. The operator determines the first tape to
load by loading the desired tape into the tape drive using the
ValueLoader's front panel controls (see
When the first tape is full or unloaded for any other reason, the
ValueLoader automatically removes the tape from the drive, puts it in its
original slot, then loads the cartridge in the next available higher
numbered slot, continuing this sequence with each available higher
numbered slot. To further determine how you want tapes loaded into the
ValueLoader's tape drive while in Sequential Mode, you may set
and options from the autoload front panel. When the
Autoload
ValueLoader is in Sequential Mode, the LCD will display
lower-right corner of the display.
