NB 7.7.3 Media ID change after media used

pastevensjr
Level 3

On a new master server my first batch of tapes has the wrong media IDs.  The robot reads 8 characters and the media ID came through as  1710L5 (last 6 chars of the barcode) instead of N01710 (first 6 chars) like it should.

I fixed the generation rules so the next batch of tapes inserted comes through as N0xxxx like we want, but then there is the issue of that first bunch of tapes.

Can I change the MediaID on these tapes while they have data on them or do I have to delete them?

I don't want to lose the data that is on them so if I can't just change the media ID, as I see it I have two choices...

1.  vmdelete them all then reimport the data.

2.  Copy all the data to the new tapes, then vmdelete them all and bring them back in as scratch tapes.

Either way is going to tie up my tape drives for a couple days which is not ideal.

 

Suggestions on which is a better path?  and if it is to copy the data how do I do that?

Option 2 or wait for them to expire. If you expire and delete the media, then reimport it, it will just pickup the internal media ID again so you'll achieve nothing.

I agree with Riaan.
Option 3: Live with it until expiration.

Some of the images were test backups that I was able to bpexpdate the image, and then vmdelete the tape, then upon inventory it came back in correctly.

Most of the other images are short term retention, so I could live with those until expiration if I had to.

But one client that I back up has a retention of 10 years, so I really don't want to leave it like that.

So can I dig up the backup ID and copy it from one tape to another?  then bpexpdate -copy 1   ?

Yes. Duplicate the tape, then expire copy 1.

is there a way to duplicate by media ID instead of by backup ID? 

I can see how to do it by backup ID but due to multi-streaming that list is very long.  I would rather duplicate the handful of tapes by media ID

Yes.
Use -id (media_id).
And -mpx to create multiplexed copy.

[root@ncbakalb008 admincmd]# ./bpduplicate -mpx -dstunit ncbakalb006-hcart2-robot-tld-0 -id 1690L5
Duplicate started 10/04/2017 15:42:22
Activity monitor job id = 1289
INF - found no images or media matching the selection criteria

images on tape reportimages on tape report

 

 

So in the screen shot above it shows that there are images on tape 1690L5.  But the bpduplicate command is telling me it isn't finding any images

The default period for bpduplicate is 24 hours ago. Add -d 09/30/2017.
One more thing - if the tapes to be duplicated are not full, NBU may choose the source tape as destination as well. Therefore best to duplicate to another pool.

I don't think duplicating to the same tapes will be an issue because I did a Freeze on all the tapes with the 'bad' media ids, but to be on the safe side, I am adding the -dp to send them to a new pool.

However bpduplicate didnt like the -d 09/30/2017 ...   it told me -d was an unrecognized option. 

[root@ncbakalb008 admincmd]# ./bpduplicate -mpx -d 9/30/2017 -dstunit ncbakalb006-hcart2-robot-tld-0 -id 1690L5
bpduplicate: unrecognized option -d

so I tried using -s and -e dates, and I tried -hoursago 300    but I am still getting nothing.

[root@ncbakalb008 admincmd]# ./bpduplicate -mpx -s 9/30/2017 -e 10/5/2017 -dp Filenet -dstunit ncbakalb006-hcart2-robot-tld-0 -id 1690L5
Duplicate started 10/04/2017 16:50:38
Activity monitor job id = 1290
INF - found no images or media matching the selection criteria
[root@ncbakalb008 admincmd]# ./bpduplicate -mpx -hoursago 300 -dp Filenet -dstunit ncbakalb006-hcart2-robot-tld-0 -id 1690L5

Apologies - I did not have manuals or a system handy when I posted last night (from my mobile phone).
Some NBU commands have -d for start-date and others -s. 

Okay, let us have a look at the error:

... found no images or media matching... 

Looking again at the screenshot on a bigger screen this morning, I see that all the images on this media are shown as 'copy 2'  (meaning original backup was duplicated to this tape).

If we look at the command usage: https://www.veritas.com/support/en_US/article.000117315   
we see that the default copy number is 1, unless specified with -cn:

-cn copy_number | -primary 
Determines the copy number to duplicate. Valid values are 1 through 10. The default is 1.

Please try to add -cn 2.

HTH

 

ok.... yesterday i could not get into this forum with my old ID so I created a new one...   now I can get in with my old one, but the new one isn't working.   go figure...    but I am the same person who started this thread...

Marianne...  i added the -cn 2 as you suggested but it failed, telling me that copy 1 already exists, because even though it is already duplicated, the disk copy has not yet been purged.

So I also added destination copy number    -dcn 3   and we are cooking now.

[root@ncbakalb008 admincmd]# ./bpduplicate -mpx -cn 2 -dcn 3 -hoursago 300 -dp Filenet -dstunit ncbakalb006-hcart2-robot-tld-0 -id 1690L5
