Check components

Check SCSI devices

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

By default, the iPBridge SCSI port uses 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 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, continue to the iPBridge SCSI port section.

Check the iPBridge SCSI port

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

2Perform a SCSI bus scan on each SCSI port. 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 i of the Appendix.

4Some older SCSI devices improperly negotiate with the iPBridge SCSI port. If older devices are not showing up, contact your service representative.

5If all devices appear, invoke the ScsiTargets command several times on each SCSI port to verify that the devices can be seen. If devices disappear then appear again, the problem is most likely a SCSI cable.

If all devices appear and remain, move to the iPBridge internal configuration section.

When changing any setting on the iPBridge the configuration must be saved by using either the saveConfiguration CLI command or through the ATTO ExpressNAV interface.

Check the serial port

1Verify you have the correct settings and that your terminal is configured to:

•Baud rate: 115200

•Data bits: 8

•Stop bits: 1

•Parity: off

•Flow control: None

•Echo: disabled

2Verify that your serial cable is less then two meters in length.

Check the iPBridge internal configuration Verify that the SCSI devices are mapped properly. Check in the ATTO ExpressNAV interface or use the routedisplay iSCSI command to show mappings. If devices do not appear, power down the iPBridge and power back on. Refer to Target management on page 9.

When changing any setting on the iPBridge, the configuration must be saved.
