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. Refer to Chapter 3, Key Concepts for System Administrators and Application Developers, in Oracle Solaris Cluster Concepts Guide for conceptual information about the disk-path monitoring daemon. Refer to the cldevice(1CL) man page for a description of the command options and related commands. For more information about tuning the scdpmd daemon, see the scdpmd.conf(4) man page. Also see the syslogd(1M) man page for logged errors that the daemon reports.
The procedures in the following section that issue the cldevice command include the disk-path argument. The disk-path argument consists of a node name and a disk name. The node name is not required and defaults to all if you do not specify it.
