Hi,
I have an older PII 400 dual processor server that uses (4) hotswap SCSI 80 pin SCA drives.
It originally had drives in bays 0, and 1, but the second drive (#1) has been removed.
Now the BIOS detects NO drives at all. It is possible that I am required to have at least 2 drives plugged in for this to work?
Any help would be greatly appreciated as I am not a SCSI expert.
These drives plug directly into the SCA sockets on the SCSI backplane, and I think they auto terminate if no drive is plugged in, but I am not sure.
I don't think termination is the problem as these are "SCA" SCSI drives. SCA drives have no onboard termination. Some of them have no jumpers at all. Termination, power, and ID's are all controlled and suplied by the system backplane. Since they plug directly into the backplane there are no SCSI cables accept the one that runs from the onboard controller on the system board to the backplane. The backplane should should auto terminate the chain at the last installed drive.
Any Ideas?
