how tapes are moving to scratch pool automatically

Where can I find the script which moves tapes to scratch pool.

Because if i want them to move now, what can i do ?

To move manually, you can run

bpexpdate -deassignempty followed by bptm -delete_all_expired (in /netbackup/bin dir).  bpexpdate is probably in .../netbackup/bin/admincmd dir

If this doesn't free up tapes, then I suspect you don;t have any tapes where the images have all expired.

excllent info from Martin..

if you are still seeing the tapes in normal volume pools  even after following the Martin suggestion. 

those tapes Previous Volume pool might not be the Scratch one..

so you can select those tapes manaully in GUI--> right click --> chage and select volume pool as Scratch to move them Manually .

only unassinged tapes can be moved  to Scratch..  if you are not able to move them to scratch.. those tapes might have valid images or waiting to get expired.. 

Thanks Ram -  I should really add that that is how works from memory ...

Worth noting, that a tape is fully expired/ unassigned when it has no assign time.  Easiest way to see this is run bpmedialist -m <media id>  - if it reports the tape is not found in the media DB, then it is expired.

I have executed "bpexpdate -deassignempty" followed by "bptm -delete_all_expired" but it didn't work.

@Ram,

I tried to move the tape to scratch pool using GUI but it gave me below error

cannot change media pool of an assigned media(91)

I found the below article and it worked.

# bpmedialist -m tape02

[root@master] /root
# bpexpdate -m tape02 -d 0
Media tape02 is due to expire at 07/15/2015 06:56:46
Are you sure that the data on this media is not critical to
your business, and you are sure you want to delete tape02 y/n (n)? y
[root@master] /root
# bpmedialist -m tape02
requested media id is not assigned to this host in the EMM database

After this the tape02 automatically moved to scratch pool

I have a question, when I try to deassign the tape02, it is asking for another media also can you explain why it is asking for the media which I didnt request to deassign.

# bpexpdate -deassignempty -m tape02
Search for empty media that meet the following criteria:
        Media id: tape02

Continue? y/n (n)y
The following empty media will be deassigned:
        Media-id:tape08    Host:media-2
        Media-id:tape09    Host:media-4

Are you SURE you want to continue y/n (n)? n
No changes made.

The reason this worked:

bpexpdate -m tape02 -d 0

Is because the tape still had unexpired images, as would heve been seen in bpmedialist -m <media id> as I explained above, if the number of valid images is >0, the tape is assigned.

As to your last question, when you run bpexpdate -deassignempty -m tape02 it found other 'empty' media, and so was just offering to expire these as well.  Normal behavior.
