You can use the bpexpdate command to expire images (you want to expire
images rather than tapes - this frees up space on the tapes and if these
are the only images will expire the tape).
However, your question implies you are rather tight on tapes in the
first place and rather than manually expiring tapes early you might want
to invest in some new ones so you can have things expire automatically.
You also don't mention how often you're running this backup. Hopefully
you don't do it just once ever 3 weeks. That is to say hopefully you do
not expire the last backup before you run the current one. If your
system crashes in the middle of the current backup you wouldn't have any
if you're overwriting the same tapes the way you imply.

Subject: [Veritas-bu] media expiration as of Start Time.
Dear All,
Please advise.. Our some of the big size backup's taking 18 hours to
complete and these backups spans to 4-5 Tapes.
The issue is all the Backup (4-5) Tapes have different expiration time.
Assume my backup start at 01:00 am and it takes 18 hours to complete. I
have the backup retention policy to 3 weeks.
Once the tapes are back after 3 weeks I can see the data expiration is
as
of 18:00 hours... etc... where my backup will start at 01:00 am and it
will fail with error 96.
Please advise how I can expire the backup images before the next Backup
Start Time..
With Warm Regards
