Good Day, 

We upgraded a netbackup master running on solaris 9 from 5.1mp3 to 60MP2. This 
master runs ndmp backups on 6 R200's with fibre direct attached IBM LTO-2 tape 
drives. After the netbackup upgrade, with no changes with the tape drives, tape 
library or netapps we started to see the following messages in the 
/etc/messages file on the netapp. We are being told by netapp and symantec that 
this is a problem with scsi commands, but they report that they can not tell us 
what the offending scsi commands are, unless we hook up a sniffer. 
So my question to this group, is Any hints on what one should  use to act as a 
sniffer for this scsi connection?

That is what company makes good sniffers, and what are the different features  
one should look for?

Thanks for any info you guys can throw this way.
