HP Hitachi Dynamic Link Manager Software Licenses - Manual (Page 370)

Specify the size of the trace file in kilobytes. Specify a value from 100 to
16000.
By specifying both the trace file size and the number of trace files, you
can collect up to 1024000 kilobytes of trace files in total.
If a value smaller than the set value is specified, the execution
confirmation message KAPL01097-W is displayed and the trace file is
deleted for the time being.
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 the same.
When all the trace files become full, the new trace data will overwrite the
oldest trace data.
-systfn number-of-trace-files
Specify the number of trace files. Specify a value from 2 to 64.
By specifying both the trace file size and the number of trace files, you
can collect up to 1024000 kilobytes of trace files in total.
If a value smaller than the set value is specified, the execution
confirmation message KAPL01097-W is displayed and the trace file is
deleted for the time being.
The trace files for which the number of files can be set are hdlmtrn.log
(n indicates a file number from 1 to 64).
-pchk {on [-intvl checking-interval]|off}
Enables or disables path health checking.
on: Enabled
off: Disabled
For a standby host, or a host connected to the Thunder 9500V series, or
Hitachi AMS/WMS series storage system, we recommend that you
activate path health checking so that you can detect errors in paths
where I/Os operations 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 specified in the last time
The explanation for the following sub-parameter describes how to specify
the checking interval.
-intvl checking-interval
Specify the checking interval between path health checks. Specify a
value from 1 to 1440 minutes depending on the user environment.
