The tape drive has a mini-SAS connector. The connector is keyed in location 4, which is the standard location
for end devices. If you use a cable other than the one recommended for use with the product, verify that it is
keyed in location 4.
CAUTION: Mini SAS connectors are keyed. Do not force a SAS cable mini-SAS connector into the tape
drive mini-SAS port because it might be keyed differently.
Library partition guidelines
Partition constraints
The library has a flexible partitioning scheme with the following constraints:
• Each partition must have at least one tape drive. One tape drive in each partition hosts the library LUN for
the partition.
• The maximum number of partitions is 21.
• Magazine slots are allocated to partitions in five-slot groups, except for a 32-slot library (Q6Q62A), in
which case the slots may be in four or five slot groups depending on whether the magazine slots are
located in the bottom module or not.
• Mailslots must be enabled for a module before they can be allocated to a partition.
A partition does not need to have a mailslot. If a partition does not have a mailslot, the magazine must be
accessed to import or export cartridges. Opening a magazine takes the library off line.
Although the mailslot magazine is shared between partitions, the mailslot elements are assigned
individually to partitions.
Partition wizards
Wizards guide you through the partition configuration process. The wizards are only accessible from the RMI.
• Basic Partition Wizard – You specify the number of partitions. The wizard removes the current partition
configuration and assigns the drives and storage slots as evenly as possible to the partitions. Any extra
drives or slots are assigned to the first partition.
Use the Basic Partition Wizard to configure partitions that will have similar resources. For a library with a
single partition, use the Basic Partition wizard to configure the number of barcode characters to report to
the host application and whether to report them from the left or right end of the label.
• Expert Partition Wizard – You add or remove partitions from the current partition configuration and then
edit each partition configuration to add or remove library resources.
Use the Expert Partition Wizard to configure partitions that will have different resources or to adjust
resource assignments for existing partitions or partitions created with the Basic Partition Wizard.
CAUTION: The library goes off line while partitions are being configured. Ensure that all host operations
are idle before running a partition wizard.
