Functional Description
The Scalar 1000 can be installed on a solid or a raised floor.
The cartridge accessor moves cartridges between storage
cells, tape drives and the Insert/Eject Station (I/E Station).
The cartridge accessor includes the gripper. A barcode
scanner on the gripper identifies the cartridges in cells. Refer
to
Cartridge Accessor
on page 2-12 for additional details. The
Insert/Eject Station allows cartridges to be added to or
removed from the Scalar 1000 without interrupting the
operation of the library. Refer to
Insert/Eject Station
on page
2-14 for additional information.
The cartridge storage cells, cartridge accessor, and tape drives
are accessed by opening the door on the front or rear of the
Scalar 1000 module in which the component is found.
Maintenance activities are performed by using this door.
Requests from the host result in cartridge movement in the
library. The primary requests are for loading and unloading
cartridges to and from the tape drives and for inserting and
ejecting cartridges to or from the library. The host maintains
records of the physical location of a tape cartridge volume in
the library. The physical location is also managed by the
library. Each volume can have a machine and operator-
readable external label to identify a volume in the library
during initial inventory and any time a volume is added to the
library. The library stores the physical location of the
cartridge in an inventory database that is based on the
cartridge bar code number (BC).
In addition to requesting movement of cartridges in the
library, the host can request status, performance,
configuration, and cartridge storage information.
