Yes.concat
Yes.concat-mirror
No. Use vxassist convert after relayout to the concatenated-mirror
volume instead.
mirror-concat

Specifying a non-default layout
You can specify one or more of the following relayout options to change the default
layout configuration:
Specifies the number of columns.ncol=number
Specifies the number of columns to add.ncol=+number
Specifies the number of columns to remove.ncol=-number
Specifies the stripe width.stripeunit=size
The following examples use vxassist to change the stripe width and number of
columns for a striped volume in the disk group dbasedg:
# vxassist -g dbasedg relayout vol03 stripeunit=64k ncol=6
# vxassist -g dbasedg relayout vol03 ncol=+2
# vxassist -g dbasedg relayout vol03 stripeunit=128k
The following example changes a concatenated volume to a RAID-5 volume with
four columns:
# vxassist -g dbasedg relayout vol04 layout=raid5 ncol=4
