Setting up Integrated Traces
When HDLM is used, the dlnkmgr command logs are output to the integrated
trace information files of Hitachi Network Objectplaza Trace Library
(HNTRLib2) (/var/opt/hitachi/HNTRLib2/spool/hntr2n.log (n indicates a
file number)).
If a lot of integrated trace information is output, the older information might
end up getting deleted in a very short amount of time. Also, if a large amount
of integrated trace information is suddenly all output at the same time, any
integrated trace information that is overflowing the buffer might not be saved
into the integrated trace files. To save as much information as possible,
change the settings for Hitachi Network Objectplaza Trace Library, increasing
the integrated trace file size and buffer size. Note that if the values are too
large, it will place a heavy load on the system. When determining these
values, be sure to consider these operational tradeoffs.
The following table lists the default values and recommended values for the
integrated trace file setting.
