If the same device shows up at several different SCSI IDs, either its SCSI ID is set the same as the ATTO ExpressPCI SCSI ID, or the cable is defective.

If a device doesn’t appear and cables and termination are set properly, try lengthening the

SCSI Reset Delay using the ExpressPCI Utilities found on the CD that came with your host adapter.

PC users should make sure that SCSI adapter firmware and Windows drivers are at the same revision level. Unless indicated otherwise, the latest drivers and firmware can be downloaded from the ATTO Technology website
