A system and method of operating a storage system is provided. The storage
system includes a tape cartridge having a magnetic tape medium and a tape
drive for reading and writing data to the magnetic tape medium of the
tape cartridge. Performance data associated with specific operating loci
(e.g., bands, directions, tracks, segments, etc.) of the tape drive and
tape medium are collected, analyzed, and stored, allowing for analysis
and detection of trends over time. In one example, tape usage events are
monitored and when they cross a threshold the system may remove
particular tapes in a preventative maintenance approach to reduce system
outage. Performance data is collected and analyzed with a portion of the
performance data being saved to emulated medium auxiliary memory (EMAM)
on the magnetic tape, and a portion of the of the performance data saved
in non-volatile storage in the drive.
