Mounting magnetic tapes based on lifecycle metrics and end of life indicators

A computer-implemented method for optimizing a global lifetime for a plurality of magnetic tape cartridges for a magnetic tape library is disclosed. The computer-implemented method includes storing a magnetic tape cartridge lifecycle table for a set of parameter values. The set of parameter values include: volume serial numbers of the plurality magnetic tape cartridges, lifetime metric values of the plurality of magnetic tape cartridges, and end-of-life-indicator values for the plurality of magnetic tape cartridges. The computer-implemented method further includes selecting a magnetic tape cartridge from the plurality of magnetic tape cartridges based on the set of parameter values and a selection criteria, wherein the selection of the magnetic tape cartridge optimizes the global lifetime of the plurality of magnetic tape cartridges in the magnetic tape library.
