RE: SCSI LTO3 Drive for NDMP Backup problems

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: 1. make sure ther are no little bent pins 2. screwed down TIGHT

If problems persist, try a different cable. Problems still, RMA the SCSI card. Lastly, RMA the Tape drive itself.
