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    hdisk3    hdisk3    0       4444228  -
mydg  mydg02    hdisk4    hdisk4    0       4443310  -
newdg newdg01   hdisk5    hdisk5    0       4443310  -
newdg newdg02   hdisk6    hdisk6    0       4443310  -
oradg oradg01   hdisk7    hdisk7    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 hdisk3    hdisk3    0       4444228   -
mydg02 hdisk4    hdisk4    0       4443310   -
