unknown or corrupt media detected in the drive on NBU 6.5.4
Helle folks,
I have problems inventorying a stand alone media and I need help.
My netbackup enviroment is next:
MASTER (NBU 6.5.4):
HP-UX 11.23
MEDIA (NBU 6.5.4):
Windows 2000 SP4
Stand-alon drive: HP COMPAQ DLT8000 (LTO2 medias)
I cofigured the STU without any problem and the tape inside was used successfully during first backup. Next day the tape was taken out of the drive and a new one media (used previously by HP Data Protector) was put in. I launched the same test policy and it said:
- A pending request has been generated for his resource request.
Operator action may be requiered. Pending Action: No action,
Media ID: A00000, Barcode: ------ and so on
It's requesting the previouse tape and it didn't reliaze that there is a different tape inside the stand-alone drive.
I suspended the tape in order to avoid that message, restarted the job and error 96 was reported.

I used previously "HP Storageworks" software for formatting the new media.
Any idea about how to solve it??
Thanks for your help.

You have to relable your tape
You have to relable your tape but you'll loose all data on it:
bplabel -m A00000 -d DLT2 -p <pool> -host sv93
Hi, The option "allow media
Hi,
The option "allow media overwrite" was set beforing testing the backup, and with the first tape worked. So I think that is not the problem.
I tried to relable the media but I cannot do it because I don't know the name of media. The inventory command doesn't report the name.
Media A00000 is the name of the first succeded backup. I need to inventory and label the new tape.

Disable standalone unload - Off topic tip
Per default Netbackup unload the media after each read/write operation on standalone drives. You can however prevent this by create a empty file:
On UNIX /usr/openv/netbackup/db/config/RB_DISABLE_REAL_UNLOADS_ON_DEMAND
On Windows [install_path]\Veritas\NetBackup\db\config\RB_DISABLE_REAL_UNLOADS_ON_DEMAND
There is a tech note as well Tapes keep unmounting between user-directed and/or application backup jobs.

Disable stand-alone drive extensions
This is from a post made by Mariane van der Berg some time ago: https://www-secure.symantec.com/connect/forums/cou...
I Think you have the same issue :
About Media usage in Standalone drives:
Have a look at NetBackup Admin Guide II under 'Reference Topics' -> How NetBackup Selects Media -> Selecting media in stand-alone drives.
Extract:
With NetBackup stand-alone drive extensions, NetBackup tries to use any labeled or any unlabeled media that is in a stand-alone drive. This capability is enabled by default during installation. The media selection process is as follows:
....
If an appropriate drive contains a volume, NetBackup tries to select and use that volume.
....
NetBackup uses media that was not used previously. If the media is unlabeled, the following actions occur:
■ NetBackup labels the media.
■ NetBackup adds a media ID to the volume configuration, if necessary. If a media ID is added, the NetBackup Media ID prefix (non-robotic) is used as the first characters of the media ID.
■ If a media ID prefix is not specified, the default prefix is the letter A. For example, A00000.
■ NetBackup adds the requested volume pool to the volume configuration (if the backup policy specifies a volume pool).
.....
Disabling stand-alone drive extensions
You can disable the stand-alone drive extensions by clearing the NetBackup media server host property, Enable standalone drive extensions. If you clear this property, NetBackup uses the same method to select media for stand-alone drives as it uses for robotic drives.

Hello Nicolai, First of all,
Hello Nicolai,
First of all, thanks for your help.
I create the file and disabled drive extensions from de GUI and everything is ok.
# vmphyinv -h sv93 -u 1
Volume configuration is up-to-date with robot contents.
The problem now is that every tape, that it what used by Data Protector, is identified with the same name: OMNI-2. What can I do to label a media with a different name?
Thanks,

I suspended OMNI-2 tape because a made a FULl backup successfully and I don't want to lose that data. I have inserted a new tape which is identified with OMNI-2 name too.

FYI
Netbackup won't overwrite a tape with valid images (backups) on it. A media suspended will not be used before all backup's on it has expired.

With standalone drives it is
With standalone drives it is always best to manually add media id's to NetBackup, then load the tapes into the drive on-by-one and Label them from the GUI or command line, using bplabel. That way you are 100% sure your hand-written labels and NetBackup internal labels match. This will also overwrite the Data Protector OMNI-2 header.
Supporting Storage Foundation and VCS on Unix and Windows as well as NetBackup on Unix and Windows.

Hi Marianne, You were
Hi Marianne,
You were right.
I created new volumes, inserted tapes one-by-one and labeled them from GUI. Now Data Protector header has been successful overwrited.
Thanks a lot for your help.
