AIX Fast Connect for Windows Problem Determination

Traces

The Fast Connect server comes with the ability to create AIX trace files to isolate problems. When a trace facility is active, information about selected events is recorded in the trace file. To obtain trace files, you must have the trace command installed on your machine. The trace command is in the bos.sysmgt.trace package.

The following trace hooks are being used by the Fast Connect server:

2EE CIFS Enter
2EF CIFS Exit
2F0 CIFS-FSS
2F1 CIFS-LOGON
2F2 CIFS-NET
2F3 CIFS-SMB PARSER
2F4 CIFS-PSS
2F5 CIFS-SMS

Trace files can be created by using either the SMIT interface or the command line interface.

From the command line:

  1. Enter: 
    trace -a -j 2EE,2EF,2F0,2F1,2F2,2F3,2F4,2F5 -o /tmp/cifs.trace

    This creates a trace file named cifs.trace in the /tmp directory.

  2. Recreate the problem.

  3. Enter: 
    trcstop
  4. Enter: 
    trcrpt -t /etc/trcfmt /tmp/cifs.trace

    The trcrpt command formats the trace file into readable text and writes a report to standard output.

From the SMIT interface:

  1. Enter the SMIT fast path: 
    smit trcstart
  2. Select the CIFS hooks for ADDITIONAL event IDs to trace field, then exit SMIT. This creates a trace file named trcfile in the /var/adm/ras directory (default).

  3. Recreate the problem.

  4. Enter: 
    smit trcstop

    then exit SMIT.

  5. Enter: 
    smit trcrpt

    and select the output format. It displays the trace file into readable format.

Logs

The Fast Connect server writes informational and error messages to a file in /var/cifs named cifsLog.
