and since bpmedialist shows this info, as Mark mentioned, and it is also
used in the available_media script, you can easily add this as a new
column to a customized version of the available_media script if you want.
I have added a column on mine for last write date and expiration date and
also allow options to be passed that will make the report only report on a
specific library or specific volume pool. I use the report to feed a
script that determines what tapes should get ejected (based on status, KB
written, last write date and expiration date) and then ejects them for me.

You can get this from "bpmedialist" pretty easily:
$ bpmedialist -U
Server Host = backup0

The expiration date is where I highlighted it.
A little awk parsing will turn this into a one-liner if the form isn't
very good for you.
You might also get a little mileage out of this script. It produces a
summary report on tape usage and a little report on retention levels and
the number of tapes that expire for each level. Note each retention level
includes the previous level, so Expire < 2 weeks is the sum of "Expiring <
1 week" and "1 < Expiring < 2 weeks". The retention levels a drawn from
the NB retention table so it'll auto-config to anything you currently have
set.
## General Data Tape Summary
Total Data Tapes: 364
Total Library Tapes: 168
Full Tapes: 255
Empty Tapes: 49
Suspended Tapes: 2
Frozen Tapes: 6
Total Cleaning Tapes: 12
## Retentions
Expiring <= 1 week: 70
Expiring <= 2 weeks: 108
Expiring <= 3 weeks: 132
Expiring <= 1 month: 191
Expiring <= 2 months: 285
Expiring <= 3 months: 286
Expiring <= 6 months: 299
Expiring <= 1 year: 314
Expiring <= 3 years: 315
The script that produces this follows. Note, this calls a little external
program called "seconds_since_epoch" which is a little C program that
returns the Unix time integer. It's also pretty easy to produce in PERL
but nearly impossible to write in standard shell...

Subject: [Veritas-bu] How to tell when all images on a tape will expire?
Let's say I have tape #123456. I want to know when all images on the tape
will expire and it will be scratched. Actually, I have about 2,000 tapes
and I want to run a report that says "these tapes will expire on these
days". We do not mix retention levels but there are many different pools
with different retention levels. No, the available_media script does not
give this information - it
does not address the future.
So...how can I determine that? Seems like a basic bit of management info.
bpimmedia will show me what images are on the tape and when the expire,
but parsing that out for 2,000 tapes and processing it (compare dates) is
not feasible. For one thing, I was hoping to run this report daily and
bpimmedia takes about 3 minutes per tape and there aren't 6,000 minutes in
a day ;)
