Library Robotics - HP StorageWorks ESL E-Series User Manual

1
The vertical and horizontal motors move the library robotics into position to pick and place tape
cartridges, and rotate the assembly 180˚ to allow the library robotics to pass cartridges between the
side storage bins and the back storage bins or tape drives. The extension axis assembly is on top
of the large robotics tray. It extends and retracts the library robotics to remove and insert the tape
cartridges into bins and drives.
The library robotics includes the optical scanner that reads bar code labels (7 characters for Super Digital
Linear Tape (SDLT) and 8 characters for Ultrium). The scanner is used to maintain an inventory of the tape
cartridges within the library. A full inventory occurs automatically whenever the library is powered on or
when the doors have been opened. An inventory of just the load ports occurs when the load ports have
been opened. Inventories can also be initiated from the host computer.
Although the library does not require tape cartridges to have bar code labels, properly labeled tape
cartridges and full storage bins speed up the inventory process and greatly improve media management.
NOTE:
If you have more than 100 unlabeled tape cartridges, your library will hang during inventory or when
you power on the library. When this happens, Going on line displays in the OCP.
