Table 7.4 Trace Level Values
Value Description
0 Does not output any trace.
1 Only outputs error information.
2 Outputs a summary of program operation.
3 Outputs details of program operation.
4 Outputs all information.
The larger the trace level value, the larger the amount of log information that is output.
As the amount of log information that is output increases, the amount of time before
existing information is overwritten becomes shorter.
To specify the size of the trace file in kilobytes, use -systfs trace-file-size. Specify
a value of 100 to 16000. When combined with the specification for the number of trace
files, the maximum total size of the trace files that can be collected is 1024000KB. If a
value smaller than the setting value is specified, an execution confirmation message
KAPL01097-W is displayed and the trace file is once deleted.
The trace files for which a file size can be set are hdlmtrn.log (n indicates a file
number from 1 to 64). The trace files are fixed in length. Thus, even if the amount of
written trace information is less than the setting file size, the size of each output trace
file is always fixed. When trace data is written to all trace files, new trace data
overwrites old trace data (the oldest file is overwritten first).
To specify the number of trace files, use -systfn number-of-trace-files. Specify a
value of 2 to 64. When combined with the specification for the trace file size, the maximum
total size of the trace files that can be collected is 1024000KB. If a value smaller than the
setting value is specified, an execution confirmation message KAPL01097-W is displayed and
the trace file is once deleted. The trace files for which the number of files can be set are
hdlmtrn.log (n indicates a file number from 1 to 64).
To enable or disable path health checking, use -pchk {on [-intvl checking-
interval]|off}.
 on: Enabled
 off: Disabled
Path health checking checks the paths that have the Online status. For a standby host, or a
host connected to the TagmaStore AMS/WMS series, Thunder 9200, or Thunder 9500V Series
storage system, we recommend that you activate path health checking to enable detection
of errors in paths where I/Os do not occur. When you specify on, specify the checking
interval of path health checking by specifying the parameter immediately following on. If
you do not specify a checking interval, path health checking is executed in the following
interval:
 When the checking interval has not been specified before, every 30 minutes (default
setting).
 When the checking interval has been specified before, the interval used in the last time.
