Automatically Creating Logical Libraries; Manually Creating Logical Libraries; Deleting Logical Libraries; Changing Logical Library Access - IBM System Storage TS3310 Setup And Operator Manual

Each logical library is specific to a tape drive interface (for example, SCSI or Fibre
Channel). Mixed media is allowed within logical libraries. For example, a logical
library can contain LTO 2 and LTO 3 tape cartridges.

Automatically Creating Logical Libraries

When the library automatically creates logical libraries, the available resources are
divided equally among the number of logical libraries created. Prior to creating
logical libraries, it is important to first designate the desired number of cleaning
slots and I/O slots (if an expansion module is present). This is necessary because
the Automatic Create Logical Library function will divide all available storage slots
among the chosen number of logical libraries.
From the Operator Panel, all remaining available resources are divided among the
number of automatically created logical libraries. Use the Web User Interface (UI)
to manually create logical libraries.
Note: On the Web User Interface, all logical libraries must be deleted for the
Automatic button to appear. If the Automatic button does not appear, delete
all existing logical libraries.

Manually Creating Logical Libraries

Every logical library must have at least one drive and one storage slot assigned to
it. For example, if the library has two tape drives and 12 slots available, the
maximum number of logical libraries that can be created is two. Up to 12 slots can
be allocated between the two logical libraries in any configuration.
If the library has only one logical library with all resources assigned to it, that
logical library must be deleted before reallocating resources to a new logical
library.
You may need to provide information for the following fields:
v Emulation Type emulates the logical library.
v Logical Library Name can be up to a maximum of 12 alphanumeric characters.
v Media Barcode Format defaults to the last 8 characters.
v Automatic Drive Cleaning is enabled by default and requires at least one
cleaning cartridge and a communication interface to the tape drive with the
ability of the tape drive to indicate that cleaning is needed.
v Number of Slots is the number of tape cartridge slots that are to be allocated to
the new logical library.

Deleting Logical Libraries

A logical library can be deleted when it is no longer needed. After a logical library
is deleted, its resources become unassigned and can be used to create additional
logical libraries or added to existing logical libraries.

Changing Logical Library Access

An administrative user can control what logical libraries a specified user can
access. This is done by modifying a user's account.
To change logical library access, you must provide the following information:
v Password - a unique string of alphanumeric characters that can be viewed and
modified by the Administrator.
