Displaying Volume Information

This is example output from this command:
V NAME RVG/VSET/CO KSTATE STATE LENGTH READPOL PREFPLEX UTYPE
v voldef - ENABLED ACTIVE 20480 SELECT - fsgen
Note If you enable enclosure-based naming, and use the vxprint command to display
the structure of a volume, it shows enclosure-based disk device names (disk access
names) rather than c#t#d# names. See “Discovering the Association between
Enclosure-Based Disk Names and OS-Based Disk Names” on page 73 for
information on how to obtain the true device names.
The following section describes the meaning of the various volume states that may be
displayed.
Volume States
The following volume states may be displayed by VxVM commands such as vxprint:
ACTIVE Volume State
The volume has been started (kernel state is currently ENABLED) or was in use (kernel
state was ENABLED) when the machine was rebooted. If the volume is currently
ENABLED, the state of its plexes at any moment is not certain (since the volume is in use).
If the volume is currently DISABLED, this means that the plexes cannot be guaranteed to
be consistent, but are made consistent when the volume is started.
For a RAID-5 volume, if the volume is currently DISABLED, parity cannot be guaranteed
to be synchronized.
CLEAN Volume State
The volume is not started (kernel state is DISABLED) and its plexes are synchronized. For
a RAID-5 volume, its plex stripes are consistent and its parity is good.
EMPTY Volume State
The volume contents are not initialized. The kernel state is always DISABLED when the
volume is EMPTY.
