What is the story on adding more disks to my node?
If you have a DN2500 or the HP9000/4xx boxes, you can add SCSI-1 by simply connecting them to the on-board SCSI port, assigning the a legal device ID and terminating the chain. This is fairly straightforward. The 9000/4xx series can have up to about 9GB of SCSI disk space. [ Maintainer’s note: This is not exactly true. See below. ] There are several restrictions to adding more disks to a DN[345]xxx box. If you have an SMS/Omti (8xxx, 11914 model) ESDI floppy/hard drive controller card, then you can add only up to two disks per node. The disk type must be ESDI, not SCSI, SCSI-2, MFM, IDE, etc. The only models which Domain/OS supports are a few 76MB disks (Micropolis, ?), Micropolis 1355 170MB, Maxtor 4380 380MB and the Maxtor XT-4380E 380MB Fast Actuator disk. You cannot use the Maxtor XT-8760E 760MB disk with the SMS/Omti controllers. I do not believe Domain/OS supports any other disk types, although there may be a few other drives that work. Contrary to Apollo’s claims, you _can_ mix
