If I shutdown the system at any other time (without powering >off) I'm fine and can boot from the RM80. Yes, I seem to recall a similar problem under 4.1BSD with RP07 type disks. The problem was something being reset on a power down on the drive and it was leading to a "bad format" error when trying to startup immediately after a power down. My 4.3 hp.c driver seems to be doing the right thing, but I cannot check this for 4.2 since I don't have 4.2 sources on line. What you probably have to do is make sure that hpaddr->hpcs1 is set to HP_DCLR|HP_GO and HP_PRESET|HP_GO (also HPOF_FMT22) when first coming up, otherwise they will never be set. That should either be done in the hpustart (as done in 4.3) or the hpstrategy routine (I think where the problem was in 4.1). The culprit in 4.1 was a missing test for initialization of the drive like: if (hpaddr->hpds & HPDS_VV) == 0 ) { instead of the (4.3) correct: if ((hpaddr->hpds & HPDS_VV) == 0 || !sc->sc_hpinit) { If sc->sc_hpinit does not exist in your driver you have to define an array which you have to manage yourself... --Haral Tsitsivas scgvaxd!ashtate!unisol!haral ----------------------------- From: Patrick Barron <pdb@sei.cmu.EDU> Subject: Sendmail problem Date: 19 Apr 87 17:40:05 GMT Sender: netnews@sei.cmu.EDU Posted: Sun Apr 19 12:40:05 1987 To: unix-wizards@brl-sem.arpa Symptom: If a sendmail process dies (kill -9, system crash, whatever) while it's trying to deliver a message, then the qf file for that message goes away.

So, if you have any information on this, please let me know, even if you already sent it to me. A number of people have pointed out that UNIX has the ability to link functions into a running program. Pointers have been given to look at the documentation for the -A and -T options of ld(1). Well, I and a number of other netters have stared at the documentation as long as our little brains can stand and the bright flash of light that was promised hasn't come to us. I know someone out there knows how this works since Franz Lisp does it. I can dig that you use "ld -A -T" to create a file that can be loaded into a specific location within a running process, but what do you do to do the actual loading? Exec? What strange arguments or calling sequences do I have to know about? As I have already recieved a number of responses requesting the results of this query, I will post a summary. Thank you.

Date: 9 Apr 87 13:18:07 GMT Keywords: routed gateways To: unix-wizards@brl-sem.arpa I am running a Sun network (all Sun 3's, OS 3.2, thinwire ethernet) which gateways through to the main ethernet at our site. My problem is that the non-gateway suns (call them 'clients') occasionally drop all information about the main network from their routing tables (sometimes they 'remember' networks connected to the main cable but forget about the main network; sometimes they forget about everything but the loopback interface and the sun ethernet). This results in user's not being able to telnet or rlogin to any machine not on the main ethernet. A 'netstat -r' on the client machines fail to show any sign of the main network at all; the same command on the gateway shows everything as it should be. Killing and restarting the routed demon ('/etc/in.routed') on the client machine fixes the problem. My understanding of the operation of routed is that the gateway routed demon should be regularly (every 60 seconds) sending out routing information packets as to what services it can preform for everyone else. For that reason I would think that (even if the NSA reached in and erased part of our routing tables :-}) the client routing tables would be back to normal after a problem within 60 seconds. This does not seem to be happening. Does anyone have any ideas as to what is actually going on? Or, failing that, some suggestion as to what I might do to further diagnose the problem?

Before we plunk down any money to Sun and DEC, we would like to have feedback from some sites already using this product. Specifically, we'd like information on: a) ease of installation b) reliability c) ease of use (our largest user group consists of lens designers, most of whom use computers out of necessity, not technical interest, none of whom like computers that get in the way of optical design). d) support Any and all information is welcome. I'll summarize what I receive back to these groups.

I hope it's getting better, but Ser/IX (Unix on an IBM Series/1) is, I believe, a version of this. (...never heard of Unix on a Series/1?, not really surprising, IBM only sold the combo for about 9 months as far as I can figure. Unfortunately 'ryesone.UUCP' (where I'm sysadmin as well as here) is one...) It's hard to say what's their fault & what's just the Series/1. One of the most maddening things is they have basically System V, but with Berkeley terminal drivers....so nothing, that does anything at all fancy, ports! The manuals are also AFU...MAYBE better for a novice, very frustrating for someone familiar with Unix. Nroff doesn't work. Little things. (AIX - System V for IBM PC-RT has similar fouled up manuals, I believe it's by the same people). On the bright side, anyone that can make a pretty bug-free C compiler for the Series/1 can't be stupid. (Though anyone who would try might be considered a little mentally unstable; it's the weirdest architecture I've ever seen....makes the 8086 look positively reasonable.) -- ../Dave Mason, TM Software Associates (Compilers & System Consulting) ..!{utzoo seismo!mnetor utcsri utgpu lsuc}!tmsoft!mason ----------------------------- From: paul@MATH.UCLA.EDU Subject: "ie0: no carrier" message on a SUN-3/160 Date: 19 Apr 87 22:35:35 GMT Sender: root@CS.UCLA.EDU To: unix-wizards@brl-sem.arpa We have a Sun-3/160 with a thick ethernet interface. It complains about "ie0: no carrier" once in a few hours. We swapped all the things we can think of, such as ethernet board, transceiver and transceiver cable, to no effect. Can someone provide some hints/ideas? Strange enough, only one workstation has this symptom, other Sun workstations seem to be happy and have no complaints.
