Displaying paths controlled by a DMP node, controller, enclosure, or

array port

The vxdmpadm getsubpaths command lists all of the paths known to DMP. The

vxdmpadm getsubpaths command also provides options to list the subpaths

through a particular DMP node, controller, enclosure, or array port. To list the

paths through an array port, specify either a combination of enclosure name and

array port id, or array port WWN. You can also display paths for devices controlled

by third-party drivers.

To list all subpaths known to DMP:

# vxdmpadm getsubpaths

The vxdmpadm getsubpaths command combined with the dmpnodename attribute

displays all the paths to a LUN that are controlled by the specified DMP node

name from the /dev/vx/rdmp directory:

# vxdmpadm getsubpaths dmpnodename=c2t66d0

For A/A arrays, all enabled paths that are available for I/O are shown as

ENABLED(A).

For A/P arrays in which the I/O policy is set to singleactive, only one path is

shown as ENABLED(A). The other paths are enabled but not available for I/O. If
