Setting The Error Log File Size; Setting The Number Of Error Log Files - Hitachi XP P9500 User Manual

4
If an error occurs, you might have to set the trace level to 1 or higher to
collect any trace information.
The higher this value is set, the more information that will be output. As the
amount of trace information to be output increases, it will take less time to
overwrite the old trace information with the new information.
For normal operation, we recommend that you set the trace level to 0. If you
set the trace level to a value higher than necessary, HDLM performance
might decrease, or trace information required to analyze the cause of an
error might be overwritten.
The following is an example of using a command to set the trace level.
# /opt/DynamicLinkManager/bin/dlnkmgr set -systflv 1
Specify the trace level as a number.

Setting the Error Log File Size

The error log file size (the HDLM manager log (dlmmgrn.log (n indicates a file
number from 1 to 16))) can be set.
You can specify a value (in KB) from 100 to 2000000 for the error log file
size. The specified value is applied for HDLM manager logs.
When an error log file reaches its maximum size, the information in the oldest
error log file will be overwritten with new information. By specifying both the
log file size and the number of log files, you can collect up to 32000000KB
(approximately 30GB) of error log information.
The following is an example of using a command to set the error log file size.
# /opt/DynamicLinkManager/bin/dlnkmgr set -elfs 1000
Specify the size of the error log file in KB.

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 32000000KB (approximately 30GB) of error logs.
The following is an example of using a command to set the number of error
log files.
