You can use the vxassist relayout command to reconfigure the layout of a volume without taking it offline. The general form of this command is as follows:
# vxassist [-b] [-g diskgroup] relayout volume [layout=layout] \ [relayout_options]
If you specify the -b option, relayout of the volume is a background task.
The following destination layout configurations are supported.
concat-mirror |
Concatenated-mirror |
concat |
Concatenated |
nomirror |
Concatenated |
nostripe |
Concatenated |
raid5 |
RAID-5 (not supported for shared disk groups) |
span |
Concatenated |
stripe |
Striped |
For example, the following command changes the concatenated volume vol02, in disk group mydg, to a striped volume. By default, the striped volume has 2 columns and a 64 KB striped unit size.:
# vxassist -g mydg relayout vol02 layout=stripe
Sometimes, you may need to perform a relayout on a plex rather than on a volume.
