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.
