Message-ID: Distribution: world Organization: Home for lost Drogons MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I have a pair of HP C3325A 2GB SCSI drives, whch I'm about to add into a FreeBSD news machine, but, alas, no manual for them. I need to connect them on the same bus - I've worked out SCSI ID, but there are 2 other jumpers, I'm presuming one is parity, the other termination enable. With both of them on the same bus, they verify ok from the BIOS (Adaptec PCI card), but I'm woried that under heavy load, if both are terminated then I may see problems. The jumpers are set as below: 012 34 56789 *** ** ***** || | | *** ** ***** This being ID 3, the ID jumpers being the leftmost block of 3. Anyone any clues what the other jumpers do, or which one of 4 or 5 is the terminator enable jumper? (Or prehaps one of the others is a terminator disable..) Thanks for any input ... Gordon
