We're running AOS 4.3 on an RT-6151 with an 'Extended ESDI' disk controller. When trying to format a Fujitsu 2263 disk using the SAUTIL format utility we get failures (I/O error, Can't init drive). The disk vendor suggested that the disk requires a 16Mb controller, and that our controller is a 12Mb transver variety. IBM controller documentation is worthless; doesn't mention transfer rates. We assumed 'Extended ESDI' meant, among other things, the higher transfer rate. Any experiences out there with similar configurations? The process of installing new disks is not new to us. We previously upgraded to a 110MB disk on this system with success. Scott Douglas College of Engineering Colorado State University scott@longs.LANCE.ColoState.Edu

I've tried to find alternate sources for ESDI disks to connect to my RT under AIX 2.2. So far I've had no luck. Apparently, it is not possible to use a non-IBM disk connected to an extended ESDI controller under AIX or AOX. Does anyone know what IBM does to their disks to make them different? Or why non-IBM disks will not work? Charlie Pilzer clp@beartrk.beartrack.com

The SAUTIL recognizes it as a 310e type drive. If you cannot get any of your drives to work with the E-ESDI, perhaps you should regress to the standard ESDI controller. It's better than having such fine drives going unused. =====----- Mark S.

I got consistent results from SAUTIL: "can't init drive" or something like that--it's been about 6 months. I've tried the disks in positions 0, 1 and 2 of the controller. No luck. What has your experience been with them? I'm very eager to hear. I don't have an ESDI (non-EESDI) controller, however. The rationale of fleshing out my disks with additional ESDI disks was that I could get rid of my ST506 controller, which right now is running two non-IBM disks along with the IBM 110mb ESDI disk as the root/boot on the EESDI controller. --- Steve Dyer dyer@ursa-major.spdcc.com aka ...!{harvard,linus,ima,m2c,rayssd}!spdcc!dyer dyer@arktouros.mit.edu, dyer@hstbme.mit.edu
