Check for problems on attached devices

Check the following in order to find problems on attached devices:

LEDs

Display panels

Firmware levels

Operability

Check host versions

Check the following to find problems on attached hosts:

Operating system version

Service pack version

Host adapter version

Host adapter firmware version

Host adapter device driver version

iSCSI driver version

If an update is required, perform the update. For an updated list of supported iPBridge host platforms and host adapters, visit www.attotech.com.

Check iPBridge product versions

For a current list of required updates, visit www.attotech.com.

1Start ATTO ExpressNAV.

To start and use the interface, including how to access the version information, refer to ATTO

Component check

Use this procedure to check system components. For more information on the commands used in this procedure, refer to CLI provides ASCII-based interface on page 35.

Checking SCSI devices

1Check SCSI devices to make sure they are all set to different SCSI IDs.

By default, the iPBridge SCSI ports use SCSI ID 7 so drives should use IDs 0 through 6 and 8 through 15.

2Check the SCSI device power. Make sure the devices are powering up.

3Watch the drive lights before, during, and after startup. Many drives have term power lights that should be on before startup and turn off when system boots.

4Verify the external terminator is the correct type and does not have damaged pins.

5Check cable integrity. Check the cables for solid connections. Make sure they are screwed down. Inspect cable ends for bent pins.

6If termination is correct, and the problem persists, try drives one at a time with different cables, adding drives and cables until the

2If an update is needed, download the update from www.attotech.com.

Refer to Updating firmware on page 25.

problem occurs. This helps pinpoint the drive or cable causing the problem.

7Check with the manufacturer of SCSI device(s) for further troubleshooting methods.

If SCSI devices appear to be working, move on to the iPBridge SCSI port section.

Checking the iPBridge SCSI ports

1Verify the iPBridge has its termination set properly. By default, termination is enabled.

2Either through the ATTO ExpressNAV or CLI, perform a SCSI bus scan on each SCSI port.

Refer to SCSI configuration commands on page 47.

If no devices appear, re-check SCSI cables and termination. If garbage information appears, the problem is most likely a bad SCSI cable or termination.

3Check the internal cabling of the SCSI device.

LVD SCSI cable lengths are limited to 12.5 meters. Longer cable lengths can cause problems. Internal cabling is also considered when calculating total cable length. For details, refer to Cabling on page iii.

4Some older SCSI devices improperly negotiate with the iPBridge SCSI port. If older devices are
