I'm curious about recent experiences with non-ibm disks on an RT. In particular, I have an RT Model 25 (soon to be 125 if I ever get my update kit) running AIX 2.2. It has two of the old ESDI controllers and 3 70MB disks. I would like to get a larger disk, but it should be compatible with my system. I guess there are two approaches: 1) Attach a new ESDI disk. The difficulty is that the new disks from IBM (114 & 310) are only supported by the EESDI controller and the EESDI disks are somehow different than the ESDI standard disks. Does anyone know what that difference is? How about running non-IBM ESDI on the old controllers? Could be a problem since you can't mix controller types. 2) Get the SCSI interface and hook up a SCSI disk. There's a big advantage here in that a SCSI tape drive could also be added (maybe). What kind of SCSI controller is available for the RT. I tried to get these answers previouly but didn't get a decent response. If anyone has tried either of the above tasks, please send me your results. I'm getting desparate and my RT is my main machine. Charlie Pilzer clp@beartrk.beartrack.com
