Info-3b2 Digest, Number 23 Thursday, October 13th 1988 Today's Topics: Problems with diagnostics Devtools/idtools ---------------------------------------------------------------------- Date: Wed, 12 Oct 88 18:28:40 BST Subject: Problems with diagnostics From: hoptoad!quaduk!graham (Graham Glen) I don't know if this is a common problem or if anybody else has come across it, but in the hope that someone has, I will describe it anyway. Our main 3B2 is a 400. It currently has 6 ports cards, 2 eports, 1 GPIB and one CTC controller fitted (Ethernet was in, is now out and will be back in again soon), 4Mb of memory and 2 190Mb Maxtor drives. The machine had been running *very* reliably for about 2 years until recently when I upgraded it to 3.1 and added some more cards (moving some of the others around in the meantime). Since then it has been Panic'ing between 1 a week and twice a day. I suspect that the real problem is just a buildup of dirt on the edge connectors on the cards exacerbated by them being moved. However, as a check that there is not something nastier lurking I want to run diagnostics on it. This is where the problem starts...... >From firmware I can happily load dgmon, show the Equipped Device Table, and see the help screen. However, if I try and list the available diagnostic phases for any device I get an error 1-03, and get put back to the dgmon prompt. If I try and run any diagnostics on a board (without specifying any particular phases - as I ca't see what they are) I get an error 1-02. >From memory I think the error message says "Error 1-03 /dgn/X. is not a regular file). Well, /dgn exists and has a reasonable looking set of permissions, it seems to contain all the necessary files for diagnostics on each device type. I tried to copy dgmon and /dgn/* from another of our 3B2's (also running 3.1), and that didn't work either. I then tried running diagnostics on the 3B2 I had copied them from, and found I get exactly the same error. Does anybody have any suggestions? Is this a known problem that Olivetti (who distribute 3B's over here) don't know about.

Devtools has been replaced with idtools, and this whole bit is available in the _3B2 Maintenance Reference Manual_. This covers how to rip apart your machine, how to put it back together :-), part lists, etc., plus the idtools disk that lets you format hard drives as well as doing other diagnostics. Fairly reliable rumors are that idtools will not format > 1024 cylinders, so there is a limit of about 140MB on drives. We're getting a Maxtor 1140 (1024cyl x 15 heads) tomorrow or so and will report our findings to this list. We have formatted 72MB CDC drives with no difficulty.
