“Host Conﬁguration Problems” earlier in this chapter).

• Unable to log on.

To log on, the display screen must be owned by the SSCP-LU

session. Remember, display screen ownership is shared between the

LU-LU session and the SSCP-LU session. When you ﬁrst start Pass

Thru, the screen is unowned. Press the System Request Key (SRK)

to transfer display ownership to the SSCP-LU session. You can then

log on to the host system.

NOTE

Remember to consult Using SNA IMF Pass Thru and the SNA IMF

Programmer’s Reference Manual for descriptions of error messages.

Those manuals list Pass Thru messages and errors returned from SNA

IMF intrinsics. For each type of error, the manuals give explanations

and suggest corrective actions.

You might encounter other error messages while using SNA IMF. See

Using the Node Management Services Utilities for generic messages

produced by NMMGR and the utilities NMMAINT and NMDUMP.

Submitting an SR

Listed below are some guidelines for submitting a service request (SR).

Some of the guidelines refer to Node Management Services (NMS)

programs (NMDUMP, NMMAINT, NMMGR, etc.). Using NMMAINT

for SNA IMF is explained earlier in this chapter. Using NMMGR for

SNA IMF is explained in Chapter 3 , “SNA IMF Conﬁguration,” of this

manual. Since SNA IMF tracing and logging are part of SNA Transport

tracing and logging, using NMDUMP to format those ﬁles is not

explained in this manual (see the SNA Link/XL Node Manager’s

Guide). For more NMS information, see Using the Node Management

Services Utilities.

Common Information

For any SR, include this common information, where applicable:

• A characterization of the problem. Describe the events leading up to

and including the problem. Try to describe the source of the problem.

Describe the symptoms of the problem.

Your characterization should include MPE commands,

communication subsystem commands, job streams, result codes and

messages, and data that can reproduce the problem.

List the context and environment in which the message occurred.

Prepare copies of the HP 3000 system console information.

Give a brief history of your site, including when SNA IMF was

installed, the circumstances that usually produce problems, other
