The cleaning light on an LTO drive turns on for the following reasons:

•

A periodic maintenance threshold has exceeded.

–

If the tape drive has processed the number of equivalent FFP,

including read and writes for the generation of the drive (this can be

converted to TB) before reaching the maximum MM.

–

The drive has processed the maximum MM for the generation of the

drive indicated (MMxE6) before reaching the maximum amount of

data that can be processed.

•

A high error rate has occurred. This can happen due to the following:

–

A head clog

–

A hardware failure on the drive

–

Bad or marginal media

NOTE:

If you perform a backup with verification, you see a cleaning request twice

as frequently as you do when you perform a backup without verification.

Verification doubles the number of passes the tape makes over the head.

NOTE:

Most backup applications support Tape Alerts. If the tape drive requests

cleaning, the backup software notifies you of the need to clean.
