The scdpm(1M) command provides DPM administration commands that enable you to perform the following tasks:
Monitoring a new disk path
Unmonitoring a disk path
Rereading the configuration data from the CCR database
Reading the disks to monitor or unmonitor from a specified file
Reporting the status of a disk path or all disk paths in the cluster
Printing all the disk paths that are accessible from a node
Issue the scdpm(1M) command with the disk-path argument from any active node to perform DPM administration tasks on the cluster. The disk-path argument is always constituted of a node name and a disk name. The node name is not required and defaults to all if none is specified. The following table describes naming conventions for the disk path.
Use of the global disk-path name is strongly recommended, because the global disk-path name is consistent throughout the cluster. The UNIX disk-path name is not consistent throughout the cluster. The UNIX disk path for one disk can differ from cluster node to cluster node. The disk path could be c1t0d0 on one node and c2t0d0 on another node. If you use UNIX disk-path names, use the scdidadm -L command to map the UNIX disk-path name to the global disk-path name before issuing DPM commands. See the scdidadm(1M) man page.
