Basic Troubleshooting

Verifying SCSI Devices in Windows NT

If running Fibre Channel-to-SCSI mapping mode, verify the Fibre Channel and the SCSI devices are recognized by the router.

Sometimes Windows NT may need to be rebooted with all SCSI devices and the router powered up before recognizing the devices.

To verify the Fibre Channel and SCSI devices:1.Navigate to the Windows NT Control Panel, and select SCSI Adapters.2.Double click the Fibre Channel HBA. The SCSI devices should be listed.

If no devices are listed, verify the router configuration, Fibre Channel HBA configuration, and cabling.

If devices are listed, verify the Fibre Channel HBA mapping mode or the AL_PA addresses.

Verifying the Router Configuration

If you are in doubt about the configuration or about the location of the error, restore the router to the factory default configuration and proceed to configure the unit one step at a time, verifying the functionality of the configuration after each change is made.

Caution: Restoring factory defaults overwrites user configurations. In the Serial/Telnet interface, use the save configuration option before resetting factory defaults to allow recovery of user configuration.

Verifying Mapping

If the router is working in Fibre Channel-to-SCSI Initiator mode and is using Indexed or SCC mapping, try changing to Auto-assigned mapping.

Verifying Devices

It may be useful to connect the SCSI target devices directly to a SCSI interface (for example, a host SCSI bus) to verify that the devices are functional.
