Yes, there's an expire option. I've just wondered if that really--
expires the tapes, or just the data within BRMS. Since the tape
doesn't need to be loaded or anything. At the time I was under stress.

might try expiring the media using BRMS instead of inztap. Its an
option on the work with media menu if I remember rightly. On Tue, Apr

IfJim,
I don't throw the tapes away right away. We put them off to the side.
ablewe start noticing that we are getting a bunch of errors we are
often
Weto track it down to just one drive throwing the errors. Once
we've replaced that drive, and ran an INZTAP with a CLEAR(*YES)
we're able to put the tape back into circulation and it no longer
has any errors. In all the years of LTO3 I think we really only have had one tape go bad.
ahave replaced a few drives.
In summary, I'd retain the bad ones long enough to determine if
there's
that'spattern in the drive.
Since BRMS we rarely INZTAP. Basically we reserve it for a backup
drivereally gone bad and we want to use that same tape right now and
not wait for expiration (since the reserve tapes are in another city...).
CLEAR(*YES) is reserved for two purposes. Verifying a tape after
a
willreplacement, and for when we go to LTO4.

Or re-initialize the tape every time it's used. That resets the
counter to make it almost worthless. I never reset the statistics
so I can see if the tape is failing in any way over its lifetime.
Also keep track of when you clean the tape drive and how that affects read/write errors.
When you start seeing write errors to the tape, time for a new tape.
Tape, cheap. Lost system that is not recoverable because the tape
was failing, bankruptcy.....
