Toasters!

I have been trying for a couple weeks now to get my 3020 to properly see an LTO Gen 3 FC Tape drive.

Environment: FAS3020, attached to Cisco MDS Fabric with ISL between two MDS9509s attached to HP Ultrium 3 LTO3 Drive.

The LTO3 drive is installed in a StorageTek L700 Library which fiber channel robotic control. The backup environment is Symantec Netbackup. There is no extra HBA cards in the FAS3020, so we are using the onboard card.

The Good:
I can manually load a tape, the Filer sees the drive/tape.

The Bad:
The system always reports back that the tape is a LTO1 200GB read only.


Naturally I tried several other tape drives and tape media, all with the same problem. I have 2 FAS940s that do not have any issue talking to LTO3 Tape drives.

I've downloaded the latest device configuration files from now, I've been working with the technical support at netapp. My best assumption is that the drives are in the wrong block mode.

Has anyone seen anything like this?
