S. Thanks so much for the response. I used the debug commands you specify and they did seem to clear the drive headers. I could see the set name and member name info in those fields as I entered 0 for all of them. Unfortunately, I am still unable to initialize a new volume on these drives (there are two ST336938LW disks I am trying to use.) The same halt occurs. Here's what I have tried since then: I have removed the HPC2474S disks from the box, just in case they were causing a problem. I found an old Quantum Fireball 2.1gb 50pin disk and hooked it up as LDEV1 and did another install from my SLT. (by the way, in case it matters, this is on MPE/ix 6.0, no patches) It took the install just fine with only a warning that it wasn't an MPE/ix disk. I assume that was just informational, as the install blew away whatever was on that disk and made it master of the system volume set. No problems there, the box came up fine following the install. Then I tried to attach the LW drives and add them to a new user set and I got the same halt. I then tried just having one of the LW drives attached and it still halted. Then I tried the other one by itself. No dice.... So, just for giggles, I hooked up one of the LW drives as id 6 and had only it and the DDS on the bus and did another install from the SLT. I got the same warning that it was not an MPE/ix disk, but then to my surprise, it stated it was truncating it to 4gb and proceeded to do the install without further problems. I was almost about to think of this as some ray of hope, until the first start norecovery following the install halted when it tried to mount the system disk. Almost an identical error, but system abort 2024 (rather than the 2029 I have been getting consistently) from subsystem 145. So here I am. I think these drives should work. The fact that everything shows up properly in mapper makes me think that I have my SCSI bus properly terminated and everything in order, but I don't know that for sure. I do have an external terminator on the back of the SE card, but I am unsure of the things on the internal cable. I have to assume it was correct in the first place when the HPC2474S disk that was LDEV1 was at the end of the cable, as this is how the box always was and it was fine. I assume that that ancient drive had the jumper set to self terminate. However, when I removed it from the bus, the DDS drive is at the end of the bus and I don't know that it has such a jumper. It does have a term power jumper but that is not the same thing. Everything shows up in mapper whether that jumper is set or not. There is also some question in my mind as to the jumper settings on the LW drives. It has the typical term power jumper, which I do not have set, and it also has an interesting jumper that says "force single ended." According to Seagate's manual, this forces the drive to operate in SE mode. Having it un-jumped lets the host controller tell the drive how to operate. I don't know whether I should or shouldn't jump this, but the drive won't mount either way, I've tried it both ways. All of this is not the end of the world by any means, this is a test box and the LW drives were sitting around. Rather than buy drives, I decided to get the adapter and give them a whirl after reading comments on this list that they should work. It is possible that the adapter is the source of the problem, however, I have used it with another Quantum Atlas 2.1gb 68 pin drive (which I don't think is LVD, by the way) and it worked fine. I was able to use the drive and add it to both a user volume set and to the system volume set. So I'm left with only a few possible conclusions: (of course, based on my limited knowledge of MPE....;-0 ) 1.) Something about those particular ST336928LW drives is just not going to work on my old 967LX's SE bus. 2.) Something about the LVD drive and the adapter I'm using is causing a problem. 3.) Something isn't right with termination or some other basic SCSI problem on my SE bus. or 4.) Possibly a bug in 6.0 based on the fact that the drive is visible, can have an install and a formatvol done to it, but simply won't mount. Sorry this is so long winded but I figured some of you may find it interesting. Your comments are welcomed and greatly appreciated.
