Is this during the phase I or phase II import? Have you even tried phase II 
imports? You have to complete phase I imports of media, then phase II imports 
of the images on those media before you can restore anything.
 
Up your logging to verbose on the master and check the bptm and bpdbm logs. I 
cant recall which log, but I think there is a bptar or similar for restore 
operations from tape.
 
If you can't get this to work, I've got a document (posted to this forum 
previously) on how to use Linux and tar to extract images from a media manually.

Subject: [Veritas-bu] Problem recovering data from set of 32 tapes



I bought a 2d hand Dell 132-T LTO3 robotic library for the express purpose of 
archiving my tremendous collection of data. I was/am a field systems engineer 
for several companies covering Desk, Laptop and server systems for about 1300 
different pieces of hardware and one aspect of my job involved getting and 
keeping a copy of every OS, App, Driver and  Utility of the many different 
hardware and systems.  I started in 1986 with Novell, Apple, Windows 3.1 and 
various flavors of Unix, CP/M, MP/M and a Myriad of software and tools used for 
fault diagnosis, troubleshooting and repair on the many US military systems I 
contracted service and maintenance for.  Since then, I have accumulated around 
200 5.25 360/720 and 1.2Mb Floppies, 500 750 and 1.44Mb 1.44 floppies, 200 
WANGDat, DAT1,2,3 and 4, QIC, TraVan, Mammoth M2 and DLT70 tapes and about 
25-30 HDD sizing from 20Mb(!) to 500Gb. 

The majority of the stuff from way-back-then is likely junk... but I consider 
it all priceless  ;-)

The data from the 5.25 and 3.5 floppies was imaged to several hundred bootable, 
self extracting, stand-alone file(s) using a product called DDC and I built a 
mini SCSI tower for reading all my WANGDat, Dat4 QIC, TraVan, Mammoth and DLT 
tapes.  I started with a 13-tape 2-drive DLT unit, progressed to a 24-tape 
4-drive DLT unit, bought a 32tape 4-drive DLT unit and then I simply ran out of 
space... so I bought the 132T 19Tb unit thinking I could surely archive 
everything on it - and add tapes as needed until I did.

Well,Using NetBackup 5.1, I managed to fill up 3/4 of that drives mix of 16 
LTO2 and 7 LTO3 tapes and then my picker burned up. Thats the gizmo that runs 
along a track, grabs the tapes and takes 'em to the reader, drive or mail-slot. 
I was dead in the water.  Well; it took 3 months, but I finally was able to buy 
a 132T-shell from an outfit in Tx, pull the picker off it, and get mine 132T 
working again. 

Trouble is, I moved the whole sheband 2x during that time (home renovation) 
lost the catalog somehow along the way and now cannot restore anything to the 
new 2Tb drives I just installed in the server.

I followed all the suggestions found on the many forums and identified 2 faults 
with the barcoding that weren't there before.  Tapes BC 00203 and 00211 were 
appearing as 0203L2 and 0211L2 and wouldn't inventory or import. The had also 
somehow migrated to the NBpool...

As they were assigned, I couldn't just move them so deassigned and then moved 
them to the correct pool (LTO2), then made 2 BC that reflected their Media ID 
and after 4-5hrs of fooling around I finally got them to inventory, updated the 
VM and now they show up in the Media List, but they still will not import.

 

The err I get is: 

Error bptm(pid=452) ERR - Cannot add client black_beauty_2, policy 
320Gb_Unknown and schedule Full to image database for import, error = a 
protocol error has occurred, skipping.

"Black_Beauty_2" is the NB master and Media Server

"320Gb_Unknown" is one of many external, temporary USB Drives I copied over to 
tape - the policy still exists but is deactivated (one time shot)

I was saving a copy of the Catalog on the D: drive under 'BP_Backup' and it is 
still there - or at least some files are but any attempt to access or read it 
results in errors that no importable records were found in the specified 
location. 

 

What am I doing wrong?  What am I missing?  All the other 22 tapes import 
flawlessly (although I still cannot restore anything)

Any ideas?

After I import all those tapes, and despite the errs on those 2 'L2' tapes 
during that process, what do I do next? 

FYI: I am using NB 5.1 on a 2k3 Standard OS Server Install

Thanks in advance  ;-)
