Try swapping in a different U320 rated terminator.

If all else fails, replace the SCSI host adapter.

The U320 SCSI host adapter is detected by the operating system, it detects some

of the connected devices on both SCSI busses, but does not detect all of the

connected devices.

Verify the SCSI devices are powered on.

Check the SCSI devices to make sure that they are all set to different SCSI ID's.

Each device on each SCSI bus must use a unique ID, including the host adapter.

Devices on Bus 1 can have the same IDs as those on Bus 2. By default, the host

adapter uses SCSI ID 7, so devices should use ID's 0 through 6, or 8 through 15.

Check cable integrity. Check the cables for solid connections. Make sure they

are screwed down. Inspect cable ends for bent pins. U320 SCSI requires high

quality cables that are specifically rated for the U320 transmission speeds.

Boot into the OSX and use the ATTO Configuration Tool to verify the host

adapter has its termination set properly. Instructions to do this can be found in

the help portion of the ATTO Configuration Tool.

Verify the external terminator is the same SCSI type as the devices (certified as

usable for Ultra320 SCSI or lower) and does not have damaged pins.

Try attaching SCSI devices one at a time with different cables, adding drives and

cables until the problem occurs. This will help pinpoint the device or cable

causing the problem.

Watch the LED indicators on the SCSI devices before, during, and after startup.

Drive lights should also flash at startup as the SCSI bus is scanned. This may

give a clue as to the root cause of the issue.

Errors are reported while trying to flash new firmware onto the SCSI host

adapter.

The ATTO Configuration Tool performs validations on the structure of the file. If

it does not pass these validations, the file is rejected. The image file may be

corrupted. Try downloading the image file from the support section of the

website again.

The software application being used to communicate with the attached SCSI

devices reports communication errors.

Check your cables. There could be slight damage to one conductor causing

intermittent failures. U320 SCSI requires high quality cables that are specifically

rated for the U320 transmission speeds.

Try slowing down the data transmission rate by lowering the sync rate for the

drive in question. To do this, launch the ATTO Configuration Tool. Double click

on the drive you want to change. The current sync rate will be displayed. Lower it

then click on commit and reboot. If this resolves the issue, the SCSI device may

need to be replaced.
