SNA Link Troubleshooting
Problem Resolution
• Always obtain a copy of the generation of the host system you are
using for ACF/VTAM and ACF/NCP. For the host system to be
compatible with the SNA link, Hewlett-Packard sets certain
operands and parameters to required values (see Chapter 2 , “SNA
Node and Link Configuration,” of this manual). Note any differences
between the actual system generation and your expectations. Keep
this information for your Hewlett-Packard support contact. This is
very important.
• Give a copy of NMCONFIG.PUB.SYS to your Hewlett-Packard support
contact.
SNA Transport Information
For problems that involve SNA Transport, include the following
additional information where applicable:
• Always issue the MPE command
SNACONTROL STATUS;NODE=
NodeName
to identify the state of the PU and the LUs in the problem node.
Inspect the output to try to locate an identification of the problem.
Keep a copy of the output from this command for your
Hewlett-Packard support contact.
The SNACONTROL commands are described in Chapter 6 , “MPE
Commands,” of this manual.
SDLC Communications Link Information
For problems that involve the SDLC communications link, include this
additional information where applicable:
• If a fatal SDLC link error has occurred, a message in this format is
displayed on the operator’s console:
Linkname = LinkName Event Type = EventType
Log Class = LogClass Location = Location
Sublocation = Sublocation Error Code = ErrorCode
State = State Cause Status = CauseStatus
Error Actions = ErrorActions
• Be sure to include this error message in the SR exactly as it appears
on the operator’s console.
• If a PSI failure has taken place, give the PSI dump file
NETDMP
nn .PUB.SYS (where nn is a number from 00 through 99) to
your Hewlett-Packard support contact for analysis.
If the problem is easily reproducible, and link-level tracing was
inactive when the problem took place, turn on link-level tracing with
the MPE command SNACONTROL START or SNACONTROL TRACEON (see
Chapter 6 , “MPE Commands,” of this manual). When the problem
has been reproduced, turn off the tracing and give the PSI dump file
