Volume belonging to the device 'metadata' is not available
Hi everyone,
I upgraded Networker from 9.1.1.7 to 19.4.0.1 (last version) following manual of upgrading but after i done it gives me error that
Volume belonging to the device 'metadata100' is not available
Information about the Disk Volume that gives this error:
Mode : appendable
media type: adv_file
Media Pool Type: Backup
i think i forgot to do a command or something before upgrade process?
If anyone can help i will appreciate this.
No Events found!

the file "volhdr" which is about 1KB in size, among other information, contains the volume label. You may see it in the text if you open the file with an editor. This file will be created/updated if the media is (re-)labeled.
As the file is missing, it seems as if it (and probably the whole array of subdirectories or even the whole path) has been deleted.
If this is not the case, please check what/where the directory "... might have gone." . If you detect another path where it might be, just correct the device properties or even delete/recreate the device. But for no reason - DO NOT LABEL THE VOLUME!
May I suggest you briefly test/verify the procedure with another new device before you switch to the 'hot' one.
Good luck.

I discovered what was the problem, it is similar of what you expected in this sentence
"If this is not the case, please check what/where the directory "... might have gone."
This directory was NFS share from Data Domain & mounted on Networker server machine, i do not know what happened during the update made this share mount becomes inaccessible on Networker Server (This was the case),
problem fixed after i added support for both NTFS3 & NTFS4 then added authenticated connections as in the next picture
It was only NFS3 and Unauthenticated connections allowed. I do not know why it was accessible before and now need to change those settings, may be because server was not turned off for 900 days!
I even not sure must both of them or one of them fixed it but anyway as it is now stable i do not want to make any changes not to interrupt production anymore.

I hope that you still remember the volume name which was mounted on this device. This is where I would start. "mminfo -m" is the command where I would start.
If you do not remember the volume name, you can scan the volume running the scanner command at the storage node which controls the device. "scanner -m device_name | more" to verify the volume label. Abort the command at the first wait. At this time you should see the volume name. If so, try to mount the volume -
DO NOT LABEL & MOUNT IT!
I am not sure what the status "volume not available..." means for an ATFD. For a tape i suspect it has been taken out of the jukebox. For an AFTD, I would guess that one unmounted the volume and deleted it from the media index. But this is a guess so far.

One final issue that came into my mind: You better verify your DDOS version and make sure that it is compatible with your new NW version. Do not forget about it!

Networker Version is the latest one 19.4.0.1
Data Domain OS version is the latest one i think is 7.5.0.5 or something around that build number, so both Networker + Data Domain OS working on the latest updated versions.
