Basic Troubleshooting

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 be solid. If it is 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 cable 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:
Channel port speed must be manually set, such as for 1 Gb/s. If set incorrectly and the
router is plugged into a Loop or Fabric, the unit may receive framing errors, which can be
found in the trace logs, and the fiber link light will be off because of the incorrect Fibre
Channel link speed. For more information on manually setting the Fibre Channel port
speed, see Chapter 3,

By default, the Fibre Channel port speed is set to 2 Gb/s. Changes to the Fibre
