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.

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

An approach for dynamically changing a copy policy associated with a cluster grid for tape storage virtualization which involves monitoring one or more statuses of a plurality of clusters associated with the cluster grid, wherein the one or more of the plurality of clusters are assigned one of a plurality of copy modes, detecting that at least one of the plurality of clusters, having a highest priority copy mode associated with the cluster grid, is unavailable, selecting an available second cluster of the plurality of clusters and changing the copy policy wherein the available second cluster is assigned the highest priority copy mode.
