Restore Failes with error 2850, media position error 86??
Hi,
I am running NBU 7.5.0.5 on a single Master/Media Win2008 R2 server. I am running NDMP backups of a NetApp Filer (OnTap 8.1). When trying to restore to that filer, I get the following job log:

Restore error(2850)
Running the troubleshooter against this tells me "an error occured". While that is certainly good information, I wish it was a little more descriptive.
I would really appreciate some quick help with this issue, I am trying to restore some pretty important stuff. Thanks in advance

Any clue in library logs? If medium error or so is recoreded, tape medium or DELL drive is suspicious.
Mount operation have to be done on DELL, but positioning operation can be done from NetApp using mt command. Are you using Data ONTAP 7-mode or Clustered Data ONTAP? mt command exist on 7-mode.
https://library.netapp.com/ecmdocs/ECMP1196461/html/cmdref/man1/na_mt.1.html
I'm not sure, but you may be able to run mt command on Clustered Data ONTAP using node shell(system node run ...).
Try positioning as below:
mt -f drive rewind
mt -f drive fsf 68
If you get error in positioning, NetBackup is mostly innocent in this case. Check logs in DELL and NetApp. if any error is logged, you may need to check if backup image is really alive in this tape.
