ATTO Technology ExpressPCI UL5D Manuale di risoluzione dei problemi
The host adapter driver may not be properly installed. Please refer to the host
adapter Installation and Operations manual for instructions on installing your OS
driver.
The firmware and driver may not be at compatible revision levels. The drivers are
updated more frequently than the firmware, therefore the revision levels are
seldom the same. There may be an occasion where the latest driver also
requires a firmware update. Verify from the web site that the latest firmware and
driver version are being used. The firmware version can be viewed when the
host adapter is detected during the computer's BIOS scan. The driver version
can be verified from within the Device Manager.
The UL5D 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 Windows 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.
