StorageTek 6 manual ACS Daily Report, Tape Volume Report

This utility provides the library administrator with the information necessary to balance mount/dismount activity across ACSs and LSMs within a library. The information is based on statistics contained in SMF records that are tallied for each cartridge movement. Total Mount and Dismount activity is categorized to show a percentage for:

•scratch mount/total mounts and average time per mount

•nonscratch mounts/total mounts, and average time per mount

•scratch mounts in a different LSM/total mounts, average time per mount, and average number of pass-thrus

•nonscratch mounts in a different LSM/total mounts, average time per mount, and average number of cartridge exchanges.

Refer to Chapter 4, “Utility Functions” on page 169 for detailed information on the Activities Report utility.
