Mounting transient tape cartridges
See "Stand-Alone Device" on page 330 for more information on stand alone
operations.
Initial Cartridge Installation
Physical cartridges may be loaded into the 3494 Tape Library after the hardware
installation is complete. The loading of physical cartridges can occur before the
teach and inventory operations. Logical volumes can be inserted after a teach
operation. The following types of cartridges may be loaded:
User volumes
Cleaner volumes
Service volume
Logical volumes
Stacked volumes
v The assignment of a specified drive for restricted use with the special
category
v The ending of the restricted usage of a tape drive
Note: A convenience I/O station feature must be installed to take
advantage of this function.
The 3494 Tape Library Mount from Input Station function supports special
usage of the convenience I/O station for the use of transient cartridges that
are not part of the library inventory. In this special-use mode, cartridges in
the convenience I/O station are mounted sequentially, used (read or
written), demounted, and returned to the convenience I/O station. This
function is available as an option in the Setup Stand alone Device window
under the Stand alone device... option in the Commands window.
User volumes are the initial set of data and scratch volumes to be
automated. Cartridges may be added to the 3494 Tape Library up to the
maximum number of available storage cells.
One cleaner volume should be installed for each frame that contains a tape
subsystem. The cleaner cartridge type depends on what media the tape
subsystem uses. The cleaner cartridges may be placed in any available cell.
Note: The external volser must match the mask value that is provided, or
the inventory operation treats the cleaner cartridge as a normal user
volume.
The service representative installs one to three service volumes, depending
on the 3494 Tape Library configuration.
If a VTS is installed, logical volumes are inserted into the 3494 Tape
Library by using the Manage Logical Volumes window (see Figure 176 on
page 281).
If a VTS is installed, the cartridges that it uses to store and manage logical
volumes cannot be loaded into the 3494 Tape Library without performing
the following first:
v Performing an initial teach of the 3494 Tape Library.
v Setting up one or more volser ranges that identify the stacked volumes
that the VTS will manage. See "Volser Ranges for Media Types" on page
237 for a description of how to enter the volser ranges.
