Table 3-26: Values for the trace level setting

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 setting up the trace level by using a command:


# /opt/DynamicLinkManager/bin/dlnkmgr set -systflv 1

Specify the trace level as a number.

(7) Setting the Error Log File Size

The error log file size (the HDLM manager log (

dlmmgr

n

.log

(n indicates a file

number from

1

to

16

))) can be set.

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.
