- Those problems seem to be a "gift" for some users. From times to time
- I have this problem whereas over machines in the campus neighborhood don't.
-
- The cause has never been clearly isolated. But it is definitely related
- to a bad interaction with power-supply events. And SCSI is maybe to
- sensible.
-
- When we did not have the UPS IBM told it was out power supply. Errors
- were only on the internal drive or on the (IBM) streamer.
-
- Ok, we installed a UPS (1.4Kva) which according to our IBM SE is enuff.
- I'm not convinced on this. As the problems started again and again
- we wanted to check that point. A local operator plugged the UPS out for a
- few seconds. Errlog showed SCSI errors on the internal disk, the printer
- ejected a sheet of paper. Still nothing with the external disk.
-
- So either the UPS is in trouble or the 320's power supplies are too weak
- and too sensible to small variations. No more precise idea yet.
- The PC-RT which was on the same place never crashed due to electrical
- problems, even without the UPS.
