Administering DMP Using vxdmpadm

Displaying All Paths Controlled by a DMP Node
The following command displays the paths controlled by the specified DMP node:
# vxdmpadm getsubpaths dmpnodename=c2t1d0
NAME STATE[-] PATH-TYPE[-] CTLR-NAME ENCLR-TYPE ENCLR-NAME ATTRS
==================================================================
c2t1d0 ENABLED PRIMARY c2 ACME enc0 -
c3t2d0 ENABLED SECONDARY c3 ACME enc0 -
The specified DMP node must be a valid node in the /dev/vx/rdmp directory.
The state of a path that is currently enabled and available for I/O is shown as
ENABLED(A):
# vxdmpadm getsubpaths dmpnodename=c2t66d0
NAME STATE[A] PATH-TYPE[M] CTLR-NAME ENCLR-TYPE ENCLR-NAME ATTRS
==================================================================
c2t66d0 ENABLED(A)PRIMARY c2 ACME enc0 -
c1t66d0 ENABLED PRIMARY c1 ACME enc0 -
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 the I/O policy is
not set to singleactive, DMP can use a group of paths (all primary or all secondary)
for I/O, which are shown as ENABLED(A). See “Specifying the I/O Policy” on page 121
for more information.
You can also use getsubpaths to obtain all paths through a particular host disk
controller:
# vxdmpadm getsubpaths ctlr=c2
NAME STATE[-] PATH-TYPE[-] CTLR-NAME ENCLR-TYPE ENCLR-NAME ATTRS
==================================================================
c2t1d0 ENABLED PRIMARY c2t1d0 ACME enc0 -
c2t2d0 ENABLED PRIMARY c2t2d0 ACME enc0 -
c2t3d0 ENABLED SECONDARY c2t3d0 ACME enc0 -
c2t4d0 ENABLED SECONDARY c2t4d0 ACME enc0 -
