The vxdmpadm utility is a command line administrative interface to DMP.
You can use the vxdmpadm utility to perform the following tasks:
Retrieve the name of the DMP device corresponding to a particular path.
Display consolidated information about the DMP nodes
Display the members of a LUN group.
List all paths under a DMP device node, HBA controller, enclosure, or array port.
Display information about the HBA controllers on the host.
Display information about enclosures.
Display information about array ports that are connected to the storage processors of enclosures.
Display information about devices that are controlled by third-party multi-pathing drivers.
Display extended devices attributes.
Suppress or include devices from VxVM control.
Gather I/O statistics for a DMP node, enclosure, path or controller.
Configure the attributes of the paths to an enclosure.
Display the redundancy level of a device or enclosure
Specify the minimum number of active paths
Display or set the I/O policy that is used for the paths to an enclosure.
Enable or disable I/O for a path, HBA controller or array port on the system.
Rename an enclosure.
Configure how DMP responds to I/O request failures.
Configure the I/O throttling mechanism.
