Troubleshooting Basic Verification
Verify Fibre Channel Connection
If SCSI devices are recognized on the SCSI bus, but do not appear to the Fibre
Channel host, it may be that the Fibre Channel link is not established. Most hubs
and switches have link indicators, showing link status. When the PSFR-CP41 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 reini-
tializes. Also verify that the media type of the PSFR-CP41 and attached hub,
HBA, or switch are of corresponding types. When using optical media, verify
that the attached device is using non-OFC type optical devices.
Verify SCSI Devices in 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 PSFR-CP41 configuration, FC HBA configu-
ration, and cabling.
If devices are listed, verify FC HBA mapping mode or ALPA addresses on the
PSFR-CP41.
Verify Configuration
A number of configuration changes may result in an invalid configuration. If you
are in doubt about the configuration, restore the PSFR-CP41 to the factory
default configuration and proceed to configure the unit a step at a time, verifying
the functionality of the configuration as changes are made.
