AHA-1510A/20A Series User's Guide Problem General problems using a SCSI drive as drive D with another SCSI drive as drive C. Action 1 Make sure that both standard hard disks are set to Not Installed or No Drive Installed with your CMOS Setup program. 2 Make sure that the SCSI drive that you want to use as drive D is set to SCSI ID 1:0. Check your drive manual for information on setting the SCSI ID for that device. 3 Make sure that SCSI parity is consistently enabled or disabled on all devices on the SCSI bus. 4 Make sure that SCSI termination is set correctly on the host adapter and the peripherals. 5 If your system is running under DOS, make sure that the disk has a DOS partition and a DOS format. Problem The system works erratically. It hangs, or the host adapter sometimes cannot find the drives. Action 1 Make sure that SCSI parity is consistently enabled or disabled on all devices on the SCSI bus. 2 Make sure that SCSI termination is set correctly on the host adapter and the peripherals. 3 Check cable length and integrity. The cable should be no longer than six meters total for the entire SCSI bus. 4 If the host adapter and drive LEDs remain on during a hang condition, make sure that the SCSI drive conforms to SCSI-1, the SCSI CCS (Common Command Set) revision or SCSI-2 specifications. 5-4 AAAAAAAAAAAAAAAAAASPCAAAAAArtuHoiAAArncAAAArtkAAAe-SAAAn1NAAApt5AAAeuD1AAAcmAAA0aAAANtAbeAAAeu:/AAAr2mAAA1:0AAA15bAAAA/1eAAA1rAAA0S8:AAA4/e4AAA90rAAA94i0eAAA1-AAAs08AAAU04AAA,2AAAsR-AAAe0AAAre0'AAAvsAAA.AAAGCAAAuAAAAAAidAAAeAAAAAAAAAEAAACAAAAAANAAAAAADAAAAAAaAAAtAAAeAAA:PAAA1aAAA1AAAg/AAAe2AAA:9AAA5/AAA9-AAA44AAAAAAAAAAAAAAAAAAAA
