Veritas Dynamic Multi-Pathing (DMP) records messages to the console and to a log file for certain system events. The events can range from critical DMP log messages to messages available for troubleshooting by Symantec support.
DMP events include:
- Enabling paths or DMP nodes
- Disabling paths or DMP nodes
- Throttling of paths
- I/O error analysis
- Host Bus Adapter (HBA) and Storage Area Network (SAN) events
You can view the log level, message, meaning, and scenarios for each DMP event.
