Paul,
I've never had had that much trouble with SCSI, but one time I was installing a system in the south of France. It just wasn't reliable.
The solution: go outside and drive a 20-foot stake in the ground, then connect the building ground to it.
So, can you transport your system to somewhere else that likely has good quality power and test it there? If that fixes it, you have a power/ground problem.

Hi Greg. Interesting idea that it could be an earth problem. I performed an earth continuity test on the server between the drive's casing and the earth in the power cable and this is showing up as all OK. I have also been zipping round plug sockets checking for earth leakage. I cannot find anything above 0.002mV which is absolutely fine. I have also fully PAT Tested my server and the UPS it is connected to and these both pass fine on all tests (Including earth continuity). I have also checked the earth live and neutral terminals for loose screws all the way back to the consumer unit. These are all OK and are making goof connections. So unless something is causing some other type of interference on the earth? Out earth connection is via the Neutral cable coming into the building. We have had a problem lately where our voltage is always unusually high, hovering between 248V and 253V which is the absolute legal maximum they are allowed to supply in the UK. (They insist they are not providing this voltage but 3 UPSs and 4 volt-meteres would not all be false readings.). Perhaps this could be causing the problem? I have yet to transport the system to a different site to test it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
