Unable to restore from tape with system assgined medi id a000

[rsakimoto]

Hi,

I have a tape that was labled by system default to A00070. Now I already put barcode sticker with  standard label (T151**). I need to restore data in that tape but it is finding the default media id A00070. When I browsed in the catalog, it can query the default media label A00070. To be able to restore its data, do I need first to do VMCHANGE the tape so as to label it with the standard barcode label, so it will reflect as Media ID: A00070 / Barcode: T151**  as the standard label? Doing that does not permit me, it says "could not change media ID.. Could not connect to vmd on host A00070. Or how can I restore its data with the default media id of A00070? I tried physical inventory vmphyinv but says -  "Skipping media ID A00070 as the media is not present in the robot slot 0
No media belongs to the specified robot (0)" When I do inventory robot and update volume config, it can scan the standard label T15**. Any known or similar scenario like this?

Thanks

Yes you need to do vmchange. The error is because you did something wrong in the command options.

[Marianne]

vmchange -barcode T151*** -m A00070

[rsakimoto]

Hi Marianne,

I got this after re-checking my vmchange. "Could not change media ID A00070: the media is allocated for use (199)."

[Marianne]

Restore waiting for media-id? Cancel the restore, then check for resource allocation on the media with nbrbutil -dump. Check the bottom section (MdsAllocations) for media-id. Clear the resource allocation with nbrbutil -releaseMDS 'allocation key'. clear all: nbrbutil -reset_all (if no other jobs are running.) Remember to do normal inventory after vmchange, then retry the restore.

Hi Marianne,

I was able to to vmchange the media id A00070 to the barcode label sticker T151*** after releaseing the allocation key via nbrbutil. Thanks to that.

So when I tried to restore the needed backup id from the tape, it was incomplete. I got this and got me confused that it says 'incorrect media found in drive index 0, expected A00070, found A00071. A00071 is also a default media id tape that is assigned to a different media pool. And when I queried A00071 in the catalog where it found it and tried to restore a sample backup id from it, it didnt push through the restore cause that tape is not in the library. Instead what I put is the A00070/T151***. Pls see logs:

You will need to mount your re-labelled tapes one-by-one to confirm what the internal label is 
(use 'vmoprcmd -d ds' after mounting) 
and then 'marry' internal and external label using vmchange.

You will first need to find A00070, do vmchange using correct external barcode, then do vmchange for A00071.

[rsakimoto]

I have vmchange already A00070 with its correct external barcode which is T151***. Then inventoried robot and now it is present in media pool. I was not able to vmchange it before cause it wont allow me due to said media is allocated for use (199). So I did nbrbutil release the allocation key assigned to media id A00070. A000070 is now present in the library which I retrieved from our vault to restore data on it. It is also a tape assigned as a monthly tape. A00071 is only a daily tape which we dont need to vmchange to match with barcode label yet. Prior to everything I did, when I retrieved the tape A00070 and put in the library, I was already gonna VMCHANGE it to its correct barcode label, but I typo error in the command the media id to -m A00071. Where it should be A00070. But then it didn't proceed cause it detected its incorrect media  assigned. And so I VMCHANGE the correct media id A00070, and then I got the error "Could not change media ID A00070: the media is allocated for use (199)." You think it got something to do when I commanded the incorrect media id (though it didnt proceed)?

Thanks

[rsakimoto]

One thing also, the tape A00070 is physically write protected (just not to be accidentally written). It doesn't matter right? I can still restore data from it?

[sdo]

Write protect does not affect restore.

[Marianne]

I agree with sdo - Write Protect does what it says - prevents tape from being written.
Write Protect turns tape to read-only - meaning you can read/restore from it.

[rsakimoto]

Yes. Why do you think when restoring the specific backup image I need, media manager is saying it found wrong tape in drive (93) where it is the correct tape I put in the library. And after I vmchange it to its correct barcode label. Cause based on the logs of restore, it found the backup image.

[Marianne]

Nope. The tape in the drive is actually 000071. Not 000070.

If you load the same tape in the drive (using tobtest) and then issue 'vmoprcmd -d ds' from another cmd window, you will see the internal label being read and displayed in the output.

The backup image info and required media-id is found in the NBU image catalog - not on the tape.

[rsakimoto]

Hi Marianne,

You are correct I checked the internal label using vmoprcmd -d ds of the tape I put in the library and it is A00071. It was mislabled the external barcode sticker. Since I have issued a vmchange to A00070 (which is A00071) and that I have to update its correct barcode sticker, how can I vmchange it (A00071) to its correct barcode label? I mean, right now it is labeled as barcode say T15** where as I need to vmchange it to T16**. Is it rescan/update barcodes option via the gui I should do?

Thanks again.

[Marianne · Accepted solution]

I'm battling a bit to understand which label is now on which tape. You cannot change the internal label - only the barcode. Let's say you put barcode label T15*** on the tape that you thought was A00070, but in fact it is actually A00071. And T16*** is actually A00070. Assuming these are sticky labels, it is not possible to swap the labels. Hopefully you have not yet linked T16*** to A00071? Assuming you have not, do this: Eject A00070 from the robot. Both tapes should now be out of the robot. vmchange A00070 to barcode T16*** vmchange A00071 to barcode T15*** Put A00070 with label T16*** in the robot and Inventory. Restore should now be fine.

[Marianne]

Best to re-label all tapes as soon as all images on it have expired. This will write internal label to match the barcode. See: https://www.veritas.com/community/forums/adding-barcode-labels-tapes-already-used-netbackup

[rsakimoto]

Hi Marianne,

Yes that's the scenario. And yes I have not yet linked (vmchange) T16** to A00071. Ok I will do vmchange to to correct both media ids to the correct barcode sticky labels which both tapes are out of the robot. I can make/print new barcode sticky labels anyhow. Will update you again soon.

Than You.

[Marianne]

Keep us updated!

Please remember to re-label all expired/unassigned tapes to make your life easier going forward.

[rsakimoto]

Yes. Will do that as well. Thanks!

[rsakimoto]

Hi Marianne,

I have properly labeled the barcode sticker of the mislabeled tapes which I also found out other tapes on the same set of my month-end duplication was mislabeled as well. I was able to label correctly the A00070 and A00071. VMChange it as well. The data I needed is only on tape A00070 with barcode label T16 *** correctly. When I did inventory robot on gui via update config option, it queried media id: A00070 barcode: T16*** and telling it will be put to standalone pool and new media id to add. I accidentally update config option and now it assigned a new media id A00080. Was it deleted? I mean the internal label? When I vmquery A00070 it still shows even on catalog, but robot type is NONE- Not Robotic (0). And when I vmquery A00080 it was added by media manager which cause I update config it that replaced A00070. How can I retrieve A00070/T16***? I tried the physical inventory:

\veritas\Volmgr\bin>vmphyinv -rn 0 -rh bdnbu2 -h bdnbu4 -ml A00080
Waiting for mount of media ID A00080 on host bdnbu2
Mounted media ID A00080 on host bdownbu002

Following error(s) detected:

Barcode conflict detected: Media A00080 is non-barcoded. There is
another media A00070 with barcode T16** in the EMM database.

How can I retrieve and make the robot to read A00070/T16**? Should I delete the assigned media id A00080? Then Run inventory robot again?

Regards
