You can specify one or more relayout options to change the default layout configuration. Examples of these options are:
ncol=number Specifies the number of columns.
ncol=+number Specifies the number of columns to add.
ncol=-number Specifies the number of colums to remove.
stripeunit=size Specifies the stripe width.
See the vxassist(1M) manual page for more information about relayout options.
The following are some examples of using vxassist to change the stripe width and number of columns for a striped volume in the disk group dbaseg:
# vxassist -g dbaseg relayout vol03 stripeunit=64k ncol=6
# vxassist -g dbaseg relayout vol03 ncol=+2
# vxassist -g dbaseg relayout vol03 stripeunit=128k
The next example changes a concatenated volume to a RAID-5 volume with four columns:
# vxassist -g fsgrp relayout vol04 layout=raid5 ncol=4
