Using the cldevice Command to Monitor and Administer Disk Paths

The cldevice command enables you to perform the following tasks:

• Monitor a new disk path

• Unmonitor a disk path

• Reread the configuration data from the CCR database

• Read the disks to monitor or unmonitor from a specified file

• Report the status of a disk path or all disk paths in the cluster

• Print all the disk paths that are accessible from a node

Issue the cldevice command with the disk path argument from any active node to perform DPM administration tasks on the cluster. The disk path argument consists of a node name and a disk name. The node name is not required. If you do not specify a node name, all nodes are affected by default. The following table describes naming conventions for the disk path.

Always specify a global disk path name rather than a UNIX disk path name because a global disk path name is consistent throughout a cluster. A UNIX disk path name is not. For example, the disk path name can be c1t0d0 on one node and c2t0d0 on another node. To determine a global disk path name for a device that is connected to a node, use the cldevice list command before issuing DPM commands. See the cldevice(1CL) man page.
