We had similar problems with a HP MSL5026 library attached to our GF920. Changed SCSI cards/cables, the drive in the tape library and eventually purchased an HP 6030 LTO3 lib to replace it. Still got the messages from both libraries until I disconnected the LTO2 from the system - haven't had an error like it since. The only part the I didn't replace was the library scsi controller card

We already try another cable, drive and terminator...
Netapp replies that we are hitting the Bug 153964, "SCSI transfers greater than 64KB hang on X2027A in Ultra320 mode". So the question is what is the blocksize Netapp uses for the dump?. It is 64KB?
Regards!

Check the SCSI connections to:
- make sure ther are no little bent pins
- screwed down TIGHT
If problems persist, try a different cable. Problems still, RMA the SCSI card. Lastly, RMA the Tape drive itself.
