RE: Tape Drive Needs to Be Cleaned

Back in the 3590 days, I remember a firmware upgrade for the library, library was over cleaning.
Our current 3573 with LTO 5 drives, each drive used about 4 hours/day, each drive gets cleaned about every 30 days, (120 hours)
According to tape support
"The drive requests to be clean by different algorithms....usage (amount of tape passing across the R/W head,
perm errors,and high rate of correctable temp errors."

No. It was an empty library. All that I checked was whether or not the library got restored without restore-type errors, not objects errors.

Initially your idea had a lot of merit, but, did that restore check to see
if some objects were not saved due to issues?

Me, I could query the BRMS files. And do a WRKOBJBRM and tell you what
volume has that object, and when it was saved, where the tape is, etc.
