Hi Matteo,

I don't use DDS but I have 9840/9940, Emulex LP8000, Networker server and 
storage node on Solaris server and Brocade 2800/3800 switches. I had also 
received Scsi errors on tape, the problem came from the firmware of the 2800 
switches. 

So, it is perhaps a good idea to first check : 

   * firmware of the SAN switches;
   * drivers and firmware of Emulex LP8000;

   * Check your zoning : be sure to define separe zone for each tape drive/HBA.

Hope this help.
Regards.

Subject: SCSI reset with DDS backup


Hi Networkers !

I've got a question for you all that use Networker in a SAN environment with 
DDS. I have Networker 6.1.3 server and storage nodes on Solaris 8 machines. I 
use a STK silo with 20 9840 tape drives. Drives and hosts are connected via 
Brocade switches and FC HBAs from Emulex (LP8000) and JNI.

Randomly, I receive SCSI reset errors on the various OS logs. This means that 
my tape drives get frozen until you reset them manually. Of course there is 
something strange not at the Networker level, but at the OS or HBA level.

So I do not pretend that someone cam help me with that, but I just wanted to 
know if someone experienced the same problem with Networker and DDS in a SAN 
env. Where did you look to find a solution ? Did you modifiy some OS parameter 
or other stuff like that ?

Thanks in advance for your help.

Regards,

Matt
