involvement. The minimum logical library simply has a name and can be thought of as a file
folder that has no contents. Drives can be placed in the file folder by using the Drive
Assignment screen of the Tape Library Specialist Web interface. Cartridges can also be
placed in the file folder, based on their volume serial (VOLSER) numbers and by using one
of the following methods (in priority order):
•
Migration of static partitioning to dynamic partitioning (requires Web enablement of
ALMS)
•
Cartridge assignment policy (automatic at the time of insertion)
•
Software application move from the I/O station (based on the source application that
issued the command)
•
Manual assignment by an operator using the Tape Library Specialist Web interface

The primary and backup copies of VOLSER assignment and physical location of cartridges
are stored in non-volatile random access memory (NVRAM).

Flexible drive assignment
This section describes flexible drive assignment in the TS3500 Tape Library.
After you enable the Advanced Library Management System (ALMS) in the TS3500 Tape
Library, you can assign drives to a logical library by using the Drive Assignment screen of
the Tape Library Specialist Web interface. You can assign a drive to be shared by multiple
logical libraries (for example, a drive used for a once-a-month job or as a temporary
replacement for a failed drive). Thus, each logical library can consist of dedicated drives and
shared drives. Each logical library maps a drive element address to the locations of both
dedicated and shared drives. This allows multiple applications to be pre-configured to
quickly use a shared drive in the future. After you pre-configure the applications for future
drive usage, you must take each shared drive offline at all but one of the applications that
have access to it. Otherwise, an application may attempt to use a drive that is in use by
another application. This may cause failed backup jobs. Also, most applications consider the
symptoms of a drive already in use to be an error that is reported as such.
The Drive Assignment Web screen supports the following capabilities which are not
disruptive to other logical libraries:
