Greetings,
I just noticed that my F760 displays, what I believe to be, its on-board external SCSI port as "Fast/Wide, Single-ended"
F760> sysconfig -v NetApp Release 6.4R1: Thu Mar 13 22:59:45 PST 2003 .... slot 0: SCSI Host Adapter 0b (Qlogic ISP 1040B, <ONLINE>) Fast/Wide, Single-ended Firmware Version 4.66.00 Clock Rate 60MHz. 4: Tape: Quantum DLT7000 245F 5: Tape: Quantum DLT7000 245F .....
I am/was under the impression that it was a Fast/Wide Differential (on-board) SCSI controller.
I have 2 DLT7000 drives connected to the Filer ... and they are absolutely differential (2 drives from a Sun L1000).
My Veritas Datacenter software keeps down'ing one of my drives and I have just ignored it due to time constraints plus the fact that I had/have one good drive still working.
But now that I am trying to troubleshoot the problem, I do not know if the problem is that I have been lucky that a "Single-ended" filer controller has been providing me good backups to my differential (one) tape drive? (Is that even supposed to work at all?)
Can anyone confirm that the output (sysconfig -v) of a F760 "Single-ended" is correct or incorrect? That is, is the on-board external SCSI port a differential or single-ended SCSI port and the "sysconfig -v" message is right or wrong?
