Resolving Common Problems

Basic Checks

under “DLCs”, each of which represents a physical communications

adapter that supports one or more ports. The Motif administration

program automatically deﬁnes and starts the DLC components when

ports are deﬁned and started. When using the command-line

administration program, however, you must explicitly deﬁne and

start the DLCs to which the ports belong.

Step 3. If links to other SNA nodes have been established, then start the

DLC/port or link station. Refer to the HP-UX SNAplus2 Administration

Guide for more information about starting DLCs/ports and link stations.

Step 4. If the DLC/port and LS are not all now active, then refer to the sections

below.

DLC/Port Fails to Start

If the DLC/port fails to start then you should check the error log ﬁle.

If you are still unable to resolve the problem then the following checks

will help you to locate the most common causes of the problem.

Step 1. Check that the required adapter cards and associated device drivers

have all been installed correctly. (Refer to the documentation that came

with these products.)

Step 2. Check that the conﬁgured adapter card number (the

adapter_number

parameter) matches that used by the hardware. For more information,

refer to the section on conﬁguring port and DLC conﬁguration

parameters in the HP-UX SNAplus2 Administration Guide.

Check the DLC conﬁguration in one of the following ways:

• If you are using the Motif administration program, zoom on the

DLC/port.

• If you are using the command-line administration program then issue

the snapadmin query_dlc command to view the DLC conﬁguration.

Step 3. If your adapter card can support more than one port, check that the

conﬁgured port number (the

port_number

parameter) matches that used

by the hardware. For more information, refer to the section on

conﬁguring Port and DLC conﬁguration parameters in the HP-UX

SNAplus2 Administration Guide.

Use the ioscan command to see which adapters are installed and what

their port numbers are.
