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

pl	pubs-01	pubs	ENABLED	ACTIVE	22880	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:
