Specifying a non-default layout

You can specify one or more relayout options to change the default layout configuration. The following are examples of using these options:

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.

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
