VERITAS Volume Manager 4.1 Administrator's Guide

Administering Volumes
Displaying Volume Information
Chapter 8264
For example, to display information about the voldef volume, use the
following command:
# vxprint -t voldef
This is example output from this command:
Disk group: rootdg
V NAME USETYPE KSTATE STATE LENGTH READPOL PREFPLEX
v voldef fsgen ENABLED ACTIVE 20480 SELECT -
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 “Using
vxprint with Enclosure-Based Disk Names” on page 79 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.
