Chapter 8

Even if the SCSI devices are displayed, they are not accessible unless the

mapping mode is auto-assigned or the mapping table has been filled when

using indexed addressing.

Fibre Channel Connection

If SCSI devices are recognized on the SCSI buses, but do not appear to the

Fibre Channel host, it may be that the Fibre Channel link is not properly

established. Most hubs and switches have link indicators, showing link status.

When the bridge is connected and powered on, this link indicator should show

a good link. If it does not, check the cabling or connections. As a means of

verifying link integrity when connected to a functional host, disconnecting then

reconnecting the Fibre Channel cable should cause momentary activity of this

indicator as the link re-initializes. Verify that the media type of the bridge and

attached hub, HBA, or switch are of corresponding types. When using optical

media, verify that the attached device is using a non-OFC type optical device.

SCSI Devices in Windows NT

■ If running FC-to-SCSI mapping mode, open the NT Control Panel, select

[SCSI Adapters] and double click on the [FC HBA]. The SCSI devices

should be listed.

■ If no devices are listed, verify the bridge configuration, FC HBA

configuration, and cabling.

■ If devices are listed, verify FC HBA mapping mode or AL_PA addresses on

the bridge.

■ If running SCSI-to-FC mapping mode, open the NT Control Panel, select

[SCSI adapters], and double click on the [SCSI controller].

■ If no devices are listed, verify the bridge configuration, SCSI controller

configuration, and cabling.

■ Windows NT must be rebooted with all SCSI devices and the bridge left on

before NT will recognize the devices.
