Verifying Fibre Channel Port 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 router
is connected and powered on, this link indicator should show a good link. If it
does not, check the cabling or connections.
One method of verifying link integrity when connected to a functional host,
involves disconnecting and then reconnecting the Fibre Channel cable. This
procedure should cause momentary activity of this indicator as the link
reinitializes.
Additionally, verify that the media type of the router and the attached hub, HBA,
or switch is of corresponding types. When using optical media, verify that the
attached device is using non-OFC type optical devices.
Note:
By default, the Fibre Channel port speed is set to 1 Gbps. Changes to the Fibre
Channel port speed must be manually set, such as for 2 Gbps. If set incorrectly and
plugged into a Loop or Fabric, the unit may receive Framing errors due to the incorrect
Fibre Channel link speed.
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.
Verify the Fibre Channel and the SCSI devices:
■
To verify the Fibre Channel devices, navigate to the Windows NT Control
Panel, select SCSI Adapters, and 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.
■
To verify the SCSI devices, navigate to the Windows NT Control Panel,
select SCSI adapters, and double click the SCSI controller.
