HDLM collects information on the detected error and trace information in the process-specific-trace information file, trace file, error logs, log for the dlmcfgmgr utility for managing the HDLM configuration and syslog. You can use the error information to examine the status of an error and analyze the cause of the error.
The following table lists and describes the error information that can be collected in logs.
Log name |
Description |
Output destination |
|---|---|---|
Process-specific-trace information file |
Operation logs for the HDLM command are collected. |
The default file path is /var/opt/DynamicLinkManager/log/dlnkmgr[1-2].log. |
Trace file |
Trace information on the HDLM manager is collected at the level specified by the user. If an error occurs, you might need to change the settings to collect trace information. |
The following is the trace file name: /var/opt/DynamicLinkManager/log/hdlmtr[1-64].log |
Error log |
Error information is collected for the user-defined level. By default, HDLM collects all error information. |

HDLM-configuration definition utility ( dlmcfgmgr ) log |
Logs are collected when the dlmcfgmgr utility is executed. |
The following is the log file name.
|
Syslog |
The HDLM messages on or above the level set by the user with syslog settings file are collected.# We recommend that you configure the system so that information at the Information level and higher is output. Syslogs can be checked using a text editor. If you want to output HDLM log information to the syslog, enable the syslog daemon. |
The default file path is /var/log/messages. The syslog file path is specified in the syslog settings file. For details, see the Linux documentation. |
HDLM boot log |
Logs are collected when HDLM starts in a boot disk environment. |
The file name of the HDLM boot log is as follows: /etc/opt/DynamicLinkManager/hdlmboot[1-3].log |
- #
When you want to configure the system so that HDLM messages are output to syslog, specify user for the system function name (Facility) in the syslog settings file.
The following shows an example when syslogd is used, the system function name (Facility) is user, and the priority level (Priority) is an information message (info) level or higher are output to the /tmp/syslog.user.log file:
user.info /tmp/syslog.user.log
