Bryan,

Way way cool. I did remember to lun map the i2000. We had also tried unplugging the fibre. However the key was the two storage commands you listed. Once I ran those the i2000 came to life for the Netapp.

By the by, when I was looking through the KB’s at Ontap I found one that specified that the Control 0 entry should be put in position 255 on the i2000. That’s where I put mine and it works but I don’t know if it really makes any difference.

David,

   Did you do your device mapping on the Scalar? I've used I2K's in the past, and once you get the I/O blades zoned in on your fabric, you have to make sure the device mapping in the I/O blades allows access to the tape drives.

  Another thought, you are using the NetApp supplied HBA's for tape drives, right? They use different HBA's for disk and tape.

  Oh, another thing, you may have to reset your tape hba ports. So, if you have a tape drive attached to, say, port 1c (card 1, port c) you have to reset the card oftentimes before it will see the drive. You may also have to do this when you re-cycle NBU. To do this, do:
> storage disable adapter 1c
> storage enable adapter 1c

Then you should be able to see the drives using "sysconfig -t" on the netapp.

  Another gotcha is that if the Scalar I/O blade has 1 WWNN with separate WWPN's for the ports on the blade, the NetApp will only look at the WWNN. So if you have 2 drives down 1 port and another 2 drives down another port, the NetApp will think those are the same 2 drives - with failover paths...

I am trying to get ndmp running to our NetApp. (everything is working on ndmp to Celera) I have fc zoned the Scaler library to the NetApp and the Scaler seems to be happy enough with zones and lun mapping. However the NetApp is not playing nice. I have been through the Ontap 7.3 tape backup guide but no matter what I do the NetApp refuses to recognize the library and tape units. Anyone know where that last button to be pushed lives? I can three way just fine with my 6.5.3 system.
