Host-Based Cleaning Of A Drive; Working With Logical Libraries - IBM System Storage TS3310 Setup And Operator Manual

Host-based cleaning will not use these slots. Host-based cleaning will import
cleaning cartridges (CLNxxx) as data cartridges and assign them to a particular
logical library.

Host-based Cleaning of a Drive

Backup applications or archive firmware applications use different techniques to
automate the process of cleaning drives. These tools specify cleaning cycles based
on cycle counts of the drive, drive requests, or regularly scheduled intervals.
The cleaning process itself requires certain considerations:
v Cleaning cartridges must be labeled with a volume serial number. In some cases,
v Insert a cleaning cartridge just as you do any other data cartridge. For example,
v Cleaning cartridges often have limited lives that can last only as long as 20
v Export a cleaning cartridge just as you would export any other data cartridge.
v The concepts of physical libraries and logical libraries must be considered when

Working with Logical Libraries

Logical libraries are virtual sections within a library that present the appearance of
multiple, separate libraries for purposes of file management, access by multiple
users, or dedication to one or more host applications. By default, the library has
one logical library, which includes all of the library's resources.
There are two ways to create logical libraries:
v Automatically - where the library divides the available resources equally among
v Manually - where an administrative user assigns the number of slots per logical
Note: When changing the logical library mode from online to offline, all host
Administrative users can create, modify, delete, and control access to all logical
libraries. Users can be given access to only certain logical libraries and denied
access to others.
At a minimum, a logical library consists of one tape drive and one slot. The tape
drive or slot cannot be shared with another logical library (an exception to the
sharing restrictions are cleaning cartridges, which can be shared among all logical
libraries). I/O Station slots and cleaning slots are shared between all logical
libraries.

prefix "CLN" might be used to identify a cleaning cartridge. The library does
not require a specific content to the label and accepts conventional cartridge
labels.
