You can use the vxdmpadm command to list DMP database information and perform other administrative tasks. This command allows you to list all controllers that are connected to disks, and other related information that is stored in the DMP database. You can use this information to locate system hardware, and to help you decide which controllers need to be enabled or disabled.

The vxdmpadm command also provides useful information such as disk array serial numbers, which DMP devices (disks) are connected to the disk array, and which paths are connected to a particular controller, enclosure or array port.

You can also use the vxdisk command to display the multi-pathing information for a particular metadevice. The metadevice is a device representation of a physical disk having multiple physical paths through the system's HBA controllers. In DMP, all the physical disks in the system are represented as metadevices with one or more physical paths.

Displaying Veritas Dynamic Multi-Pathing (DMP) information includes the following topics:

See Retrieving information about a DMP node.

See Displaying consolidated information about the DMP nodes.

See Displaying the members of a LUN group.

See Displaying paths controlled by a DMP node, controller, enclosure, or array port.

See Displaying information about controllers.

See Displaying information about enclosures.

See Displaying extended device attributes.

See Displaying the paths to a disk.

See Administering DMP using vxdmpadm.
