We use Veritas NetBackup 3.2 as our backup solution on a Solaris2.6 machine.  
When we do full backups over the weekends, the backup jobs are multiplexed onto 
the AIT tapes located in a SpectraLogic Treefrog Media Library.  The tape drive 
unit in this library is an AIT-2 drive.  

The tape library houses 15 tapes in total.  The tapes that were loaded for WKE 
were:

Slot1:  WKE016  AIT2    trouble importing
Slot2:  WKE017  AIT2    trouble importing
Slot3:  WKE018  AIT2    trouble importing
Slot4:  WKE019  AIT2    trouble importing
Slot5:  WKE020  AIT2    trouble importing
Slot6:  WKE006  AIT1    imported okay
Slot7:  WKE007  AIT1    imported okay
Slot8:  WKE008  AIT1    imported okay
Slot9:  WKE009  AIT1    imported okay
Slot10: WKE010  AIT1    imported okay
Slot11: WKE011  AIT1    imported okay
Slot12: WKE012  AIT1    imported okay
Slot13: WKE013  AIT1    imported okay
Slot14: WKE014  AIT1    imported okay
Slot15: WKE015  AIT1    imported okay

We retrieved the tapes from our offsite location.  Since the tapes had expired, 
we had to import them back into the database.  To be able to restore the 
server,  we have to import all 15 tapes back into the database.   During the 
1st step  (PHASE1) of the import, we were able to import all the AIT1 but it 
gave us MEDIA READ ERRORS and MEDIA POSITION ERRORS while reading AIT2.  

The restore that we want however seems to have some fragments on these AIT2 
tapes.  Fragments 4 to 9 are on the AIT1 tapes which we can read but fragments 
1 to 3 must be on one of those AIT2 tapes.  Note that the backups were 
multiplexed and compressed.

Is there a way to force a bpimport of the fragments that it can read.  I'm 
hoping that the slice that failed would be contained within fragments 4to9.  Or 
is all the fragments absolutely necessary to perform the recovery.  

Also, does anyone have any ideas why we would not be able to do an import of 
the images off an AIT2 tape.  Any suggestions are greatly appreciated.

Thanks,
Mitch
