Displaying Plex Information
Listing plexes helps identify free plexes for building volumes. Use the
plex (–p) option to the vxprint command to list information about all
plexes.
To display detailed information about all plexes in the system, use the
following command:
# vxprint -lp
To display detailed information about a specific plex, use the following
command:
# vxprint -l plex
The –t option prints a single line of information about the plex. To list
free plexes, use the following command:
# vxprint -pt
The following section describes the meaning of the various plex states
that may be displayed in the STATE field of vxprint output.
Plex States
Plex states reflect whether or not plexes are complete and are consistent
copies (mirrors) of the volume contents. VxVM utilities automatically
maintain the plex state. However, if a volume should not be written to
because there are changes to that volume and if a plex is associated with
that volume, you can modify the state of the plex. For example, if a disk
with a particular plex located on it begins to fail, you can temporarily
disable that plex.
NOTE A plex does not have to be associated with a volume. A plex can be
created with the vxmake plex command and be attached to a volume
later.
VxVM utilities use plex states to:
• indicate whether volume contents have been initialized to a known
state
