Location Coordinates

A numbering system is used to identify components of the library. Figure 2-13
illustrates how the cartridge slots within the library are numbered.
Figure 2-13. Library Location Coordinates

Slots

Slots are numbered from the bottom to the top and from the front to the back within
each magazine cartridge. Slot locations 1 to 9 are in the lower cartridge, and slot
locations 10 to 18 are in the upper cartridge.
Slot locations 1 to 3 can be configured as I/O Station slots to import and export tape
cartridges. When the I/O Station is configured, the number of data cartridge slots is
reduced to 15.
The library beeps a warning when a host computer accesses the library while the I/O
Station is open. When this occurs, the Accessor stops traversing the library and the
library queues SCSI commands for 5 minutes.
Slot locations 17 and 18 can be configured as cleaning cartridge slots for both
automatic cleaning and manual cleaning. If only one slot is allocated for cleaning
cartridges, slot location 18 is selected. The cleaning slots are used for all drives in the
physical library. When the library has two cleaning cartridges, the cartridge with the
higher cleaning count usage is selected for the automatic cleaning function.

Drives

Drives are numbered from the bottom to the top within the library. Hence, the lower
tape drive is Drive 1, and the upper tape drive is Drive 2. When the library is
configured with two tape drives, the physical library can be partitioned into two
logical libraries. Each logical library has one drive and one magazine for storage slots.
The I/O Station slots and cleaning cartridge slots, however, are shared by the two
logical libraries.

Power Supply Units

Power supply units are numbered from the left to the right at the rear of the library.
