SCSI hard drives and devices have a jumper setting to configure the SCSI ID. Each SCSI device must have a different ID. The jumper/s are set for the following positions across 3 pairs of pins : : : = SCSI ID = 0 no jumpers - usually for the boot hard drive : : I = SCSI ID = 1 : I : = SCSI ID = 2 : I I = SCSI ID = 3 I : : = SCSI ID = 4 I : I = SCSI ID = 5 I I : = SCSI ID = 6 I I I = SCSI ID = 7 This gives a total of 8 possible SCSI devices on one SCSI controller.
Hi when you start the pc and goes to the scsi utilities and scans for device its not finding the device attached to it sioit gives you this message you can see if the terminator connect to the device is properly connected and its in its place ,also press CTRL+A to get into the adapter setting and in the scsi utilities section scan the devices if it finds it then check the id of the device how much its set to it should not be the same of the scsi card id .by default scsi card id is 7 but be sure.
The hard drive needs to be set as the first SCSI ID device boot device..
The hard drive needs to have the jumper set to SCSI ID 0, the CD and FDD can be set to SCSI ID 1 and SCSI ID 2. No SCSI devices can have the same SCSI ID number unless it is on a different SCS controller.
Usually, SCSI devices come with the termination built into the device. Older devices actually had two or three terminating resistor packs plugged into the card or drive circuit board. More modern ones have DIP switches to turn the termination on or off.
Essentially, on a SCSI daisy chain ribbon cable with multiple connectors, only the first and last physical device needs to be terminated. Usually SCSI devices come from the factory already terminated. If you have only one device to connect check and see if there is a DIP switch to change. I would go ahead and connect it. If it works, it's probably already set properly.
That said, I have worked with daisy chains of SCSI devices where a particular device would only work if it were terminated even if it was in the middle of the chain. s
Incorrect Jumper setting (SCSI ID) Each device on the card/controller cable must have unique ID and must be of the proper type for the card/controller...although some like 50-pin SCSI I and II Are interchangeable, larger, newer drives using Ultra, Ultra-Wide and Differential technologies are not.
Typically the controller is set at 7 or 15, so each attached device (CDROM, HDD, Scanner, Plotter, Tape, etc is allowed to use 0-6 or 0-14 depending on controller type.
Doublecheck that you are not trying to use SCSI-Fast, Wide or Ultra controller with the wrong type/technology drive or (gasp) Differential (used mostly for Tape, Robots, Jukeboxes and CD or DVD Arrays) The others won't work... Diff will smoke the drive.
To get to the BIOS for your server, press F10 at start-up. This should get you there to verify if settings are detecting SCSI devices. If they are there, you may have to reinstall the SCSI controller drivers. Good Luck.

The most common cause is that setup does not have the driver for a SCSI device or is detecting storage devices in the wrong order, such as that CD-ROM drive first.
Press F6 when setup first starts and provide a driver for the mass storage device that will hold the operating system files.
Check to make sure all adapters and controllers are working properly.
Check power to all devices. Reseat adapters and controllers.
For SCSI devices ensure:
1. The SCSI cabling is properly installed.
2. SCSI devices are terminated.
3. SCSI devices are correctly addressed. And
4. The BIOS correctly recognizes all SCSI adapters.
Also, be sure the SCSI boot drive is addressed as 0.
Check the manufacturer's recommedation for configuring SCSI adapter and Hard Disk Drives. Try replacing the adapter before replcing the drive(s).
For EIDE Drives:
1. Check the controller.
2. Ensure file I/O and disk access are set to standard. And
3. Ensure that the system drive is the first device recognized by the controller.
For IDE and ESDI drives:
1.Check the cabliing and controller.
2. Check the Drive setup in the BIOS for master/slave relationships. And
3. Ensure the drive is properly recognized in the BIOS.
