Common Network Problems
Investigate the Link
created while link level tracing was enabled. Send both the PSI
dump file and the link trace file to your Hewlett-Packard
representative for additional analysis.
• Check the MPE/iX log file for I/O error logging. Format the log file.
Keep a copy of the file and the output for your Hewlett-Packard
representative to study.
NOTE If you lose connections on an NS 3000/iX Point-to-Point link as a result
of successive power failures, you can recover the connections by issuing
the following commands:
NETCONTROL NET=niName;DELLINK=linkName
NETCONTROL NET=niName;ADDLINK=linkName
DTC/X.25 iX Network Link Problems
The DTC/X.25 iX Network Link operates using a DTC/X.25 Network
Access card on the DTC. For problems that involve the DTC, perform
the following steps when applicable:
• Issue the LINKCONTROL linkname; STATUS=DIAGSTATS command on
the LAN link, where linkname is the name of the DTS link. Inspect
the output and attempt to identify the problem. Retain a copy of the
output from this command for your Hewlett-Packard representative.
• Use the OpenView DTC Manager to verify the status of the
DTC/X.25 Network Access card if you are using PC-based network
management. Use TermDSM to verify the status of the DTC/X.25
Network Access card if you are using host-based network
management.
