Changing the number of logical libraries (Configuration > Logical Libraries)
This option allows you to specify the number of logical libraries for the physical tape library. For
more information about logical libraries, see
Logical libraries (page 18)
.
Access to this feature requires the administrator password.
Changing the library configuration (Configuration > Library)
This option allows you to specify the drive that is assigned as master drive and the library mode,
and define how many slots are active and whether the mailslots are enabled.
Access to this feature requires the administrator password.

Library Master Drive:
This option designates which drive acts as the master and hosts the
library LUN.
NOTE:
The library's SCSI ID will be the master drive's SCSI ID with a LUN of 1.
•
Library Mode:
The library supports three behavior modes: Random, Sequential, and
Automatic. The library automatically detects the required mode from the series of SCSI
commands it receives; however, you can also change the mode. Choose the operating mode
based on the capabilities of the software controlling the tape cartridges. The library mode
can be set independently for each logical library.
•
Reserved Slots:
This option sets the number of reserved slots in the library. Reserved slots
are slots that can be accessed by the RMI and the OCP, but are invisible to the host and
backup software. On the MSL4048 and MSL8048, you can reserve up to 46 slots. On the
MSL8096, you can reserve up to 94 slots.
•
Mailslots enabled:
This option enables or disables mailslots. On the MSL4048 and MSL8048,
all three mailslots are enabled or disabled based on this setting. On the MSL8096, you can
choose to enable the lower-left mailslot (three slots), the upper-right mailslot (12 slots), both
mailslots (15 slots), or disable the mailslots. All three mailslots are enabled or disabled based
on this setting.
•
Auto Cleaning
: This option enables or disables automatic cleaning.
Library modes
The library supports three behavior modes: Random, Sequential, and Automatic.
Random mode
: In Random mode, the device does not automatically load tapes into the tape
drives; it waits for commands from the software or operator to load and unload tapes. Random
mode is used with a full featured or a robotics-aware backup application and is the most common
mode of operation. Your backup software must support robotics, which might require an additional
software module.
Sequential mode
: In Sequential mode, the device automatically loads and unloads tapes from
the drive. Sequential mode is used when the backup software is NOT robotics-aware or was
designed for standalone drives only.
In Sequential mode, the library will only use the lowest-numbered tape drive.
The operator begins the sequence by loading the desired tape into the tape drive. When a tape
is unloaded for any reason, the device automatically removes the tape from the drive, returns it
to its original slot, then loads the tape from the next available higher numbered slot.
