Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

This undoes changes made to the volume so far, and returns it to its original
layout.
If you cancel a relayout using vxtask abort, the direction of the conversion is
also reversed, and the volume is returned to its original configuration.

Converting between layered and non-layered volumes
The vxassist convert command transforms volume layouts between layered
and non-layered forms. The command has the following syntax
# vxassist [-b] [-g diskgroup] convert volume [layout=layout] \
[convert_options]
If you specify the -b option, the conversion of the volume is a background task.
The following conversion layouts are supported:
Mirrored-stripe to striped-mirrorstripe-mirror
Striped-mirror to mirrored-stripemirror-stripe
Mirrored-concatenated to concatenated-mirrorconcat-mirror
Concatenated-mirror to mirrored-concatenatedmirror-concat
You can use volume conversion before or after you perform an online relayout to
achieve more transformations than would otherwise be possible. During relayout
process, a volume may also be converted into an intermediate layout. For example,
to convert a volume from a 4-column mirrored-stripe to a 5-column
mirrored-stripe, first use vxassist relayout to convert the volume to a 5-column
striped-mirror as follows:
# vxassist -g mydg relayout vol1 ncol=5
When the relayout finishes, use the vxassist convert command to change the
resulting layered striped-mirror volume to a non-layered mirrored-stripe:
# vxassist -g mydg convert vol1 layout=mirror-stripe
