Discovering the Maximum Size of a Volume
To find out how large a volume you can create within a disk group, use
the following form of the vxassist command:
# vxassist [-g diskgroup] maxsize layout=layout [attributes]
For example, to discover the maximum size RAID-5 volume with 5
columns and 2 logs that you can create within the disk group dgrp, enter
the following command:
# vxassist -g dgrp maxsize layout=raid5 nlog=2
You can use storage attributes if you want to restrict the disks that
vxassist uses when creating volumes. See “Creating a Volume on Specific
Disks” on page 236 for more information.
