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.
The maximum size of a VxVM volume that you can create is 256TB.
