OK can anyone work this one out?
If I connect my drives in this order they now appear to work fine. If I swap any of them over to any other combination I get the random read-write errors I was getting before.
SCSI Card (Termination set to on) HP DAT72 HP LTO2 HP LTO1 HP LTO4 Terminator (built onto cable) I'm back again! :)
OK, so after 2 successful backups on my LTO4 drive, I set another one off yesterday and lo-and-behold it has broken again! It is doing the same thing as before, I set off the writing to tape whether it be using tar or just dd/catt-ing 1s and 0s to the tape, the drive. It starts to write to the tape then stops dead. Most of the time with the error rmtio Error: failed to write filemark. What exactly does this error mean? If I erase the tape it works fine and if I run the HP LTT Read write test it works fine. So as before, I thought one of the other drives might be playing it up. I disconnected all other drives, problem still occurs. (First time this has happened). I replaced the SCSI controller with a different one. Problem still there. Also changed the SCSI cable again. Problem still occurs. This is happening for two different HP 1760 and also my LTO3 Ultrium 920 drive. The only common thing here is that these 3 drives are 320Mbps SCSI LVD and all my others are 160 or 40 mbps LVD. Could this be a problem? My cards are all 160MBps. Saying that though the LTO3 tape drive worked fine for ages (over a year) with no trouble on the same hardware. I have not installed any updates since before I had the problems and nothing has been changed configuration-wise with the server other than removing the un-neccesary graphics card (re-installing it doesn't affect the problem). Any advice on how can I diagnose this problem further? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
