A good preventive maintenance program is another way to maintain a low level of hardware errors. The data center should establish schedules for cleaning tape drives, changing air filters on the disk drives or tape drives, and vacuuming the printers. If LOGREC indicates an excessive amount of hardware errors, the data center should run hardware diagnostics and tests as part of the preventive maintenance program.
Ongoing maintenance of the tape library should include cleaning, degaussing (demagnetizing), and recertifying tapes. Tape‑cleaning mechanisms that also demagnetize tapes are available.
