List Images On DiskPool Before Phase I Import

Is there a way to query a diskpool to get a list of images on it before I initiate a Phase I import? 
I am hesitant to run the Phase I import until I have time to finish the Phase II import as I have been burned in the past where NBU will expire the images off disk because the Phase I sets a 1 week retention on the images in the catalog.
The diskpool I want to query if from a legacy NBU environment that has been decommisioned.
 

I was hoping I could use bpstsinfo to grab the info, but it requires a mediaid which isn't created until Phase I

NBU 7.6.0.2 on RHL

    As far as I know the disk media id is generated as soon as you add disk volumes in netbackup.. It wouldn't really wait for you to run phase 1 import.. run the "nbdevquery -listdv" command and it should list the media id that you are looking for.

    No, NBU knows nothing about the images, so the only way is to run phase 1 import.

    If the storage is basic or advanced disk, you could just run ls -al (Unix) or dir (win) directly on the 'disk' and look at the filenames.

    Thanks Martin, so after the Phase I import can I extend the retention using bpexpdate on the images so I can have more time to get the Phase II done?

    I've just done a test:

    - backup to basic disk STU on master "A" Windows 2008 R2 SP1 NetBackup Server v7.6.1.2 - backup of some files with 1 day retention

    - CIFS/SMB network copy of backup image files to basic disk STU on master "B" Windows 2012 R2 NetBackup Server v7.7

    - phase 1 import on master "B"

    - on master "B" - bpimagelist -d 01/01/1970 00:00:00 -option ONLY_PRE_IMPORT, to get the image ID, then a bpimagelist -backupid blah -L -option ONLY_PRE_IMPRT, which shows expiring tomorrow.

    - on master "B" - bpexpdate -backupid blah -d 31/12/2015 23:59:59

    - on master "B" - bpimagelist -backupid blah -L -option ONLY_PRE_IMPORT

    ...which shows new/correct future date.

    .

    I would think that catalog behaviour/functionality is irrespective of storage unit type and irrespective of OS upon which NetBackup Server is running, so I think you'll be ok be doing a phase 1 import and then setting a future date (...unless anyone on here knows different?).

    Interesting, because I thought Phase I import didn't read in retention, so where did your retention of 1 day come from?  I though after a Phase I there was a generic 1 week retention on the image until a Phase II was done and then the "real" retention was applied.

    Maybe I missed that - let me test again...

    If the storage server is added in netbackup then you could try running the bpstsinfo command that could help you list the images i.e. backupid of images present on the ost.. This command is usually used to compare and get a list of images present in Netbackup catalog vs images only on the storage and helps in identifying orphan images. But this could help you get the list of images that you are looking for "bpstsinfo -comparedbandstu -storage_server < storage_server > -stype < server_type > -lsuname < lsu_name >" To get the server_type and the lsu_name you can use the nbdevquery commads

    Testing with two backup images copies, after phase 1 import, I see:

    D:\>bpimagelist -idonly -d 01/01/1970 00:00:00 -option ONLY_PRE_IMPORT -L | findstr /i "^$ ^Backup Expir Copy"

    ....so, yes, expiration is one week in the future for the image header and the copy details...

    ...now setting one image to expire at end of year...

    D:\>bpexpdate -backupid hserver_1438881613 -d 31/12/2015 23:59:59
Are you SURE you want to change hserver_1438881613
to expire on      31/12/2015 23:59:59 y/n (n)? y​

    ...and now the imagelist command shows...

    ....so it does appear to have worked - but probably best to wait one day and re-check (to see if some background processes 'change' things for us)... and/or wait a week - and see if the unchanged phase 1 image expires, and hopefully the updated phase 1 image will hang around.  Hmm... I have a VM - I'll shutdown, snapshot, reboot, change date to two weeks in the future, stop/restart NetBackup, and see if image still exists...

    Yea I looked at that option earlier but unfortunatly -media_id is required.  Since it hasn't done a Phase I yet there is no Media ID defined for it
