Displaying volume information

You can use the vxprint command to display information about how a volume is

configured.

To display the volume, plex, and subdisk record information for all volumes in the system,

use the following command:

# vxprint -hvt

The vxprint command can also be applied to a single disk group:

# vxprint -g mydg -hvt

This is example output from this command:

V NAME RVG/VSET/CO KSTATE STATE LENGTH READPOL PREFPLEX UTYPE

PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE

SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE

SV NAME PLEX VOLNAME NVOLLAYR LENGTH [COL/]OFF AM/NM MODE

SC NAME PLEX CACHE DISKOFFS LENGTH [COL/]OFF DEVICE MODE

DC NAME PARENTVOL LOGVOL

SP NAME SNAPVOL DCO

v pubs - ENABLED ACTIVE 22880 SELECT - fsgen

pl pubs-01 pubs ENABLED ACTIVE 22880 CONCAT - RW

sd mydg11-01 pubs-01 mydg11 0 22880 0 c1t0d0 ENA

v voldef - ENABLED ACTIVE 20480 SELECT - fsgen

pl voldef-01 voldef ENABLED ACTIVE 20480 CONCAT - RW

sd mydg12-02 voldef-0 mydg12 0 20480 0 c1t1d0 ENA

Here v is a volume, pl is a plex, 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.

Note: The headings for sub-volumes (SV), storage caches (SC), data change objects (DCO)

and snappoints (SP) can be ignored here. No such objects are associated with these

volumes.

To display volume-related information for a specific volume, use the following command:

# vxprint [-g diskgroup] -t volume

For example, to display information about the volume, voldef, in the disk group, mydg,

use the following command:

# vxprint -g mydg -t voldef

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
