In this output, dg is a disk group, dm is a disk, v is a volume, pl is a plex
(mirror), 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 plex(es) and subdisk(s).
Displaying Free Space in a Disk Group
Before you add volumes and file systems to your system, make sure you
have enough free disk space to meet your needs. Use the Volume
Manager to request a display of free space.
To display free space in the system, use the following command:
# vxdg free
The following is an example of vxdg free command output:
GROUP DISK DEVICE TAG OFFSET LENGTH FLAGS

To display free space for a disk group, use the following command:
# vxdg -g diskgroup free
where -g
diskgroup
optionally specifies a disk group.
