Administering Disk-Path Monitoring
Disk path monitoring (DPM) administration commands enable you to receive notification of
secondary disk-path failure. Use the procedures in this section to perform administrative tasks that
are associated with monitoring disk paths.
The following additional information is available:

Note -
Disk paths are automatically added to the monitoring list monitored when I/O devices are added
to a node by using the cldevice command. Disk paths are also automatically
unmonitored when devices are removed from a node by using Oracle Solaris Cluster commands.
