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 sdg 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 sdh 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.
The headings for sub-volumes (SV), storage caches (SC), data change objects (DCO) and snappoints (SP) can be ignored in the sample output. No such objects are associated with the volumes that are shown.
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
If you enable enclosure-based naming, and use the vxprint command to display the structure of a volume, it shows enclosure-based names for the disk devices rather than OS-based names.
The output from the vxprint command includes information about the volume state.
