HP Hitachi Dynamic Link Manager Software Licenses - Manual (Page 268)

You can specify a value from 2 to 16 for the number of HDLM manager log
files.
By specifying both the log file size and the number of log files, you can collect
up to 32000000KB (approximately 30GB) of error logs.
The following is an example of using a command to set the number of error
log files.
# /opt/DynamicLinkManager/bin/dlnkmgr set -elfn 5
Specify the number of error log files by a number.
Setting the Trace File Size
Trace files for which a trace file size can be set are hdlmtrn.log (n indicates
a file number from 1 to 64). The length of a trace file is fixed, regardless of
how much trace information is actually in the file.
For the trace file size, you can specify a value (in kilobytes) from 100 to
16000. If you specify a value smaller than the setting value, the KAPL01097-
W message will be displayed to confirm the execution, and the trace file will
be temporarily deleted.
When all the trace files become full, the oldest file is overwritten with any
new trace data.
By specifying both the trace file size and the number of trace files, you can
collect up to 1024000 KB of trace data.
The following is an example of using a command to set the trace file size:
# /opt/DynamicLinkManager/bin/dlnkmgr set -systfs 2000
Specify the size of the trace file in KB.
Setting the Number of Trace Files
Trace files for which the number of files can be set are hdlmtrn.log (n
indicates a file number from 1 to 64).
For the number of trace files, you can specify a value from 2 to 64. If you
specify a value smaller than the value that has already been specified, the
KAPL01097-W message will be displayed to confirm the execution, and the
trace file will be temporarily deleted.
By specifying both the trace file size and the number of trace files, you can
collect up to 1024000 KB of trace data.
The following is an example of using a command to set the number of trace
files:
# /opt/DynamicLinkManager/bin/dlnkmgr set -systfn 10
