EFFECTS ON THE CARTRIDGE INVENTORY

If an initialize element status operation is performed on the cartridge loader,

the request does not count toward the total number of elements requested in

the Number of Elements field.

5.3 EFFECTS ON THE CARTRIDGE INVENTORY

The library updates the cartridge inventory whenever it is powered on,

whenever a magazine is inserted, or whenever the cartridge access port door

is opened, then closed again. During the inventory it checks for the presence

of a cartridge at each location and scans the bar code labels. This section

describes how the library updates the cartridge inventory.

Ta b l e 5 - 1 and Ta b l e 5 - 2 illustrate the various outcomes of a requested scan

operation and the effect on the cartridge inventory.

 A request is made to scan a cartridge in a storage location and the scan

operation completed successfully (the bar code scanner was able to read the

label on the cartridge or the location was empty). See Ta b l e 5 - 1 for details

about how the cartridge inventory is updated.

 A request is made to scan a cartridge in a storage location and the operation

failed because the bar code scanner was unable to read the label on the

cartridge or if the cartridge does not have a label. The scan will not fail if the

location is empty. See Ta b l e 5 - 2 for details about how the cartridge inventory

is updated.
