Before you add volumes and file systems to your system, make sure that you have enough free disk space to meet your needs.

To display free space in the system, use the following command:

# vxdg free

The following is example output:

GROUP DISK      DEVICE    TAG       OFFSET  LENGTH   FLAGS
mydg  mydg01    sda       sda       0       4444228  -
mydg  mydg02    sdb       sdb       0       4443310  -
newdg znewdg01  sdc       sdc       0       4443310  -
newdg newdg02   sdd       sdd       0       4443310  -
oradg oradg01   sde       sde       0       4443310  -

To display free space for a disk group, use the following command:

# vxdg -g diskgroup free

where -g diskgroup optionally specifies a disk group.

For example, to display the free space in the disk group, mydg, use the following command:

# vxdg -g mydg free

The following example output shows the amount of free space in sectors:

DISK   DEVICE    TAG       OFFSET  LENGTH    FLAGS
mydg01 sda       sda       0       4444228   -
mydg02 sdb       sdb       0       4443310   -
