HP XP P9500 Storage - Manual (Page 206)

You can specify a value (in kilobytes) from 100 to 2000000 for the error log
file size. The specified value is applied for HDLM manager logs.
If each error log file reaches the specified size, the information in the old
error log file will be wrapped around and will be overwritten with new
information. By specifying both the log file size and the number of log files,
you can collect up to 32000000 kilobytes (approximately 30GB) of error logs
in total.
The following is an example of setting up the error log file size by using a
command:
# /opt/DynamicLinkManager/bin/dlnkmgr set -elfs 1000
Specify the size of the error log file in kilobytes.
Setting the Number of Error Log Files
The number of the error log files (the HDLM manager log (dlmmgrn.log (n
indicates a file number from 1 to 16))) can be set.
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 32000000 kilobytes (approximately 30GB) of error logs in total.
The following shows an example command that is used to set the number of
error log files:
# /opt/DynamicLinkManager/bin/dlnkmgr set -elfn 5
Specify the number of error log files in numbers.
Setting the Trace File Size
Trace files for which you can set a trace file size 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 is displayed to confirm execution, and the trace file is 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 kilobytes of trace data.
The following shows an example command that is used to set the trace file
size:
3-140
