Displaying All Paths Controlled by a DMP Node
The following command displays the paths controlled by the specified DMP node:
# vxdmpadm getsubpaths dmpnodename=c2t1d0s2
NAME STATE[A] PATH-TYPE[M] CTLR-NAME ENCLR-TYPE ENCLR-NAME
=============================================================================
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
==============================================================================
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 125 for more information.
You can also use getsubpaths to obtain all paths through a particular host disk controller:
# vxdmpadm getsubpaths ctlr=c2
NAME STATE[A] PATH-TYPE[M] DMPNODENAME ENCLR-TYPE ENCLR-NAME

c2t2d0 ENABLED PRIMARY c2t2d0 ACME enc0
