We have a F720 that we purchased in February with a Sony SDX-510C (AIT-2) that has never functioned properly (we have managed to get ONE tape backup of our system). We have been in contact with many NetApp engineers and they have yet to solve our problem. We have used the command "dump 0f nrst0a /vol/vol0" successfully once; on subsequent tries, the dump fails with these error messages:

nucleus> dump 0f nrst0a /vol/vol0 DUMP: Dumping tape file 1 on nrst0a Thu Apr 27 10:06:13 CDT [isp_main]: isp_error_proc: isp 0b.3 0xfffffc0000ca0860 transaction error #1 ( 0x8000 0x700 0x0 ) - 17/29 Thu Apr 27 10:06:13 CDT [isp_main]: isp_error_proc: Selection timeout on 0b.3 - 17/30 Thu Apr 27 10:06:13 CDT [isp_main]: isp_error_proc: Selection timeout on 0b.3 - 17/31 DUMP: open of nrst0a failed. DUMP: Retry the open?: ("yes" or "no") yes Thu Apr 27 10:06:23 CDT [isp_main]: isp_error_proc: Selection timeout on 0b.3 - 17/32 DUMP: open of nrst0a failed. DUMP: Retry the open?: ("yes" or "no") no DUMP: DUMP IS ABORTED

We have tried AIT-1 tapes as well, in addition to swapping out the motherboard (really!), changing dip switch settings, changing tape drives, different cables and different SCSI terminator (internal setting and external blocks). One of the NetApp engineers tested the drive on a F760 and she says it worked fine. They all swear this tape drive will work on our system with the dump command.

Any ideas or help would be sincerely appreciated.

Thanks! Amy
