Sun Microsystems SL8500 manual Performing CAP Activities, Dismount Sequence

Automated Mode of Operation

4.The host command is translated by the library controller into motion commands for the robot.

5.The cartridge is taken from its slot and placed in the drive.

6.The library returns status to the host that the mount operation is completed.

7.The drive then performs the read/write activity directed by the host.

Dismount Sequence

A simplified dismount sequence involves the following steps:

1.A host requests that a specific VOLID be dismounted from a drive.

2.The library transmits to the host that the VOLID is located in the drive and the library is available to satisfy the dismount request.

3.The library assumes responsibility for the dismount.

4.The host command is translated by the library controller into mechanical commands for the robot.

5.The cartridge is taken from the drive and placed into its home slot.

6.The library returns status to the host that the dismount operation is completed.

The library then awaits another activity directed by the host or continues those activities waiting in the library’s queue of commands.

Performing CAP Activities

Note – This section describes general CAP activities applying to all libraries. For specific information on CAP activities in partitioned libraries, see “Using CAPS in a Partitioned Library” on page 53.

The CAP door contains a standard CAP A (on the left, as viewed from the front); an additional CAP (CAP B, on the right) is also available. CAPs allow you to import (enter) cartridges and export (eject) cartridges from the library.

A single CAP contains three magazines; each magazine contains 13 cells, allowing import/export of up to 39 cartridges at a time. The magazines can be removed from the CAP to import cartridges in a batch mode. Rotation of the CAP is accomplished through a motor. CAP operations are controlled by the HBZ logic card.

The CAP magazines span the lower three rails and on the right side of the library only. To import or export a cartridge from the top rail on the right side, a HandBot places the cartridge in an elevator slot to accomplish the move.
