Viewing the Media Usage Log
The Media Usage Log lists information regarding data written and read
on the media and lists statistics pertaining to soft and hard read and
write errors. The media usage log collects information on all media that
have ever been in the library, including media that are no longer in the
library. Lifetime media usage metrics are associated with the cartridge
and are kept on the embedded cartridge memory.
The log reflects what the drive reports from the embedded cartridge
memory whenever the media is unloaded. If the tape cartridge was
never mounted and unloaded, it will not appear in the log. When the
log file reaches its maximum size, old information is deleted as new
information is added. This may affect the amount of available historical
data.
The log provides the following information:
• Volser — Media cartridge barcode label
• SN — Media cartridge serial number
• Mfr — Media cartridge manufacturer
• Date — Media cartridge manufacturing date (format: YYYYMMDD)
• Type — Media type
• Mounts — Cartridge mount count
• RRE — Recovered read errors
• URE — Unrecovered read errors
• RWE — Recovered write errors
• UWE — Unrecovered write errors
• LW — Cartridge lifetime MB written
• LR — Cartridge lifetime MB read
• Enc — Cartridge encryption status (U=Unknown, E=Encrypted,
N=Not Encrypted)
