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

You can also apply the vxprint command to a single disk group:

# vxprint -g mydg -hvt

This example produces the following output:

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 first 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.

You can ignore the headings for sub-volumes (SV), storage caches (SC), data change objects (DCO) and snappoints (SP) 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 example produces the following output:

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

v   voldef    -           ENABLED   ACTIVE    20480      SELECT       -           fsgen

If you enable enclosure-based naming, vxprint 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.
