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
