Logical Library Mode Settings - IBM TS2900 Setup, Operator, And Service Manual

Note: It is recommended to enable the Auto Clean function on the library. With the Auto Clean
function enabled, drive cleaning occurs automatically. The only time Auto Cleaning must be
disabled is when your Backup Application requires that it has control.

To configure the library access mode settings for the logical library:
1. In the Configure Library menu in the left navigation pane of the Web User Interface, click

| Physical/Logical
2. In the Logical Settings, select the Library Mode:
|
v Random - In random mode, the library allows the server's (host's) application software to select
any data cartridge in any order.
v Sequential - In sequential mode, the library's firmware predefines the selection of the cartridges.
After initialization, the firmware causes the library to select the first available cartridge found
(counting from the lowest Column/Tier position through the highest cartridge position in your
library) for loading into the drive. See "Location coordinates and element addresses" on page 9.
– Loop - When Library mode is Sequential with Loop mode Enabled, the cartridge in the lowest
|
Column/Tier cartridge position is loaded after the cartridge in the highest Column/Tier
cartridge position is filled with data and sent back to its home position. This mode allows
endless backup operations without user interaction.
|
– Auto load - When Library mode is Sequential with Auto load mode Enabled, the first available
|
cartridge (the lowest Column/Tier cartridge position that contains a cartridge) is loaded
automatically if the library powers ON, or resets, with an empty drive. If the library powers ON
with a cartridge already in the drive, sequential mode starts from the home position of that
cartridge, unless the host issues a rewind and unload command to the drive. In which case the
next cartridge in sequence will be loaded into the drive.
|
To start Sequential mode if Auto load is not Enabled, use the Move Cartridge command to load the
|
first cartridge into the drive. The sequence starts from the home position of that cartridge.
Cartridges need not to be in contiguous slots.
To stop Sequential mode, use the Move Cartridge command to unload the drive. This command
cancels Sequential mode; the next sequential cartridge is NOT loaded.
To restart Sequential mode, use the Move Cartridge command again to load a cartridge; the loading
sequence resumes from the home position of that cartridge.
v Number of active slots - Select the number of active slots to assign in your library. Selecting the
number of active slots defines the number of storage slots, number of cleaning/inactive slots,
whether the I/O Station is enabled/disabled, and whether auto cleaning is allowed. The first digit
configures the number of active storage positions (4, 6, 8, or 9). The second digit configures Column
5, Tier 1 of the magazine as an I/O Station (0 when disabled, and 1 when enabled). The Auto
