Missing Cartridges

A cartridge is marked as missing when:

  • Cartridge Recovery cannot find a cartridge in the library.

  • It cannot examine all recorded locations for a cartridge (home cell and drive, if the cartridge has a recorded drive location).

For example, when Cartridge Recovery cannot examine the home cell in an offline LSM or an offline drive, and when it does not find the cartridge in other locations, it marks the cartridge missing.

Cartridge Recovery preserves the cartridge's home location unless it examines the cartridges' home cell and finds another cartridge there. In this situation, it marks the cartridge “homeless," with a minus one (-1) in the home_lsm field.

When Cartridge Recovery finds a cartridge that was missing, it changes that cartridges' status to “home" or “in drive" in the database, depending where it found the missing cartridge.

  • If the cartridge is found in a cell other than its recorded home cell, Cartridge Recovery checks the cartridges' home cell to see whether it has found a duplicate cartridge.

  • If the cartridge is not in its recorded home cell, Cartridge Recovery records the cell in which it was found as its new home cell.

  • If the new cartridge is a duplicate, Cartridge Recovery reports this on the Event Log. The duplicate cartridge is not ejected.

  • If Cartridge Recovery finds a “homeless" cartridge in a drive, it does not assign a new home cell. When the cartridge is dismounted, the dismount process assigns a new home cell.
