I've got a pretty specific problem, if anyone can shed some light on it I would greatly appreciate it. The setup: a 386 system w/ 2 Novell Disk Coprocessor Boards(DCB) 2 internal Wren III drives This system works w/ 1 Wren III off each DCB for duplexing on a Novell network. Objective: add an external Wren IV off each external DCB connection so that they are also duplexed Note: the Wren IIIs & IVs all have embedded SCSI controllers, all drives have been tested and work individually, I have talked to Novell, CDC, and CMS( the people who OEMed the Wren IVs) to no avail...they all say it should work but aren't any help. According to the manuals on SCSI chaining the first and last controllers are supposed to be terminated. Following this(to me) that means the DCB and either the III or IV is supposed to be terminated. Not knowing the whether the internal or external drive is the last in the SCSI chain I tried both combinations to no success(terminate III/no terminate IV and no terminate III/terminate IV). In accordance to the rules both drives on a DCB have different SCSI addresses( 0 and 1), but does it matter which in the chain has which number? Am I doing something wrong, is there an incompatibility, what??????i Please reply and I will post a summary if there are enough requests. Thanks. ------- Tom Vandenberg {..uunet..uwvax!uwmcsd1..}!marque!studsys!vanden vanden%studsys@marque.UUCP {..uwvax..arpa..}!studsys.mu.edu!vanden
