Has anyone tried to attach a non-DEC disk to the SCSI port on a VAXstation-3100 yet? I have ordered a diskless unit and am hoping one of the fast, high capacity CDC 5.25" disks (e.g. Wren 3-6) will work... Robert Mutel (BITNET: rlm%iowa.physics.uiowa.edu@cunyvm) (ARPA: rlm%iowa.physics.uiowa.edu)

Only the DECStation-3100 has an integral controller. You have to purchase a VS3100 with the RZ22 or 23 (or RZ55 or TZ30) in order to get the SCSI controller. Check the VAX Systems book from the Reference service to check the configs. It shows all the configs and also states that the diskless VS3100 does not have a disk controller. I think that DEC is falling short on the VS3100 by not making the SCSI adapter integral to all configs like Sun does with its workstations... sigh... art stine sr network engineer clarkson u abstine@clvms.clarkson.edu

------- The VAXstation 3100 is an NCR 5380 asynchronous only SCSI based system. It may work but your disk would most likely have to "trick" the system into thinking it is a DEC disk. Now on the DECstation 3100 (supports either synchronous or asynchronous devices) I don't think you would have this problem. I posted an article in this notesfile several days ago that describes the DECstation 3100 and how to add 3rd party disks to that system. The above assumes Ultrix as the OS. I don't know what VMS does on the VAXstation 3100. --- Ricky Palmer Ultrix Advanced Development --- Digital Equipment Corporation --- Nashua, New Hampshire

I couldn't help but noticing that in scsi_data.c there is a "tz88" defined claiming to be an Exebyte EXB-8200. I plugged our EXB-8200 in and the system did, in fact, recognize it and claim it had an attached TZ88. When trying to use said, it complains: "drive selftest failed, code = 0x8". Sigh. The question then becomes is DEC assuming something about this Exebyte drive that I don't know. (Someday, kernel sources will arrive which will make this question much easier to answer...)

------- You could have one of two things wrong: your distribution is pre-FRS, i.e., your running bits that are field test or some pre-release version or your Exabyte has a problem. We have noticed that some earlier Exabytes have some microcode problems. Try to get ahold of the latest version of the drive, microcode, and Ultrix kit and then try it. --- Ricky Palmer Ultrix Advanced Development --- Digital Equipment Corporation --- Nashua, New Hampshire --- ...
