12 ! AN-DBP-076a: Configuring the QLogic QLA2342L Fibre Channel (FC) Host Bus Adapter (HBA) on Windows

Server 2003 with Overland REO and NEO products

Overland Storage REO SERIES™

Note: The REO uses high LUNS (192 and up) for the VTL and its virtual

tapes.

Troubleshooting the Fibre Environment

If some devices are not listed in the Windows Device Manager, you might

need to take additional steps.

Here are a few basic troubleshooting guidelines:

! Verify whether the settings (topology and speeds) are correctly set for

all FC components.

! Determine whether the environment uses switch zoning and or LUN

masking.

! Determine whether there are updates for the software utilities.

! Inspect FC ports to determine whether the FC links exist.

! Verify that you are using the correct driver and firmware (check for

updates).

! Inspect FC components, such as cables, small form-factor pluggable

(SFP) modules, and gigabit interface converter (GBIC) transceivers.

Checking Fibre Topology and Fibre Speeds on the REO

1 In the REO GUI, select Network Configuration.

2 In the Fibre Channel Configuration section, verify that the Link

State is Online.

3 Set the desired Link Speed (that is, change the setting to force a 1 GB

or 2 GB connection).

4 Set the desired Topology (that is, change the setting to force a

Fabric/Point to Point or Loop (NL_Port) topology).
