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 for more information.
Note The maximum size of a VxVM volume that you can create is 256TB.
