where dg is a disk group, dm is a disk, v is a volume, pl is aplex, and sd is a subdisk. The
top few lines indicate the headers that match each type of output line that follows. Each
volume is listed along with its associated plexes and subdisks.
To display volume-related information for aspecific volume,use thefollowing command:
# vxprint -t volume
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 62 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 stateof itsplexes atany momentis 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.
