DMP notifies vxesd of major events, and vxesd logs the event in a log file (/etc/vx/dmpevents.log). These events include:
Marking paths or dmpnodes enabled
Marking paths or dmpnodes disabled
Throttling of paths i/o error analysis HBA/SAN events
The log file is located in
/var/adm/vx/dmpevents.log but is symbolically linked to
/etc/vx/dmpevents.log. When the file reaches 10,000 lines, the log is rotated. That is, dmpevents.log is renamed dmpevents.log.X and a new dmpevents.log file is created.
You can change the level of detail in the event log file using the tunable dmp_log_level. Valid values are 1 through 4.
# vxdmpadm settune dmp_log_level=X
The current value of dmp-log_level can be displayed with:
# vxdmpadm gettune dmp_log_level
For details on the various log levels, see the vxdmpadm(1M) manual page.
