Seite druckenRemove any non-vital PCI cards from the system to determine if there is a PCI
bus conflict.
Disconnect any SCSI devices from the host adapter and reboot the computer. If
this resolves the issue, investigate the SCSI cable or SCSI target devices as
described in the section below.
If the computer still does not boot, try installing the host adapter in a different
computer. If the host adapter works in the new computer, try updating the flash
on the host adapter as described in the "Installation and Operations" manual.
Then try it again in the original computer.
If it still fails, report this as a possible interoperability issue between the host
adapter and the computer.
If the problem follows the host adapter, replace it with a new adapter.
The Mac freezes or hangs.
Disconnect all devices from the SCSI card and reboot the system.
If the system still freezes:
Remove any non-vital PCI cards from the system to determine if there is a PCI
bus conflict.
Remove the SCSI host adapter and test it in a different computer (not the same
model).
If the problem follows the adapter, replace the host adapter with a new one.
If the system no longer freezes after disconnecting the SCSI devices:
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 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 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. If a drive LED remains on when the
computer freezes, suspect a problem with that drive.
