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:
# vxassist [-b] [-g diskgroup] relayout volume [layout=layout] \ [relayout_options]
If specified, the -b option makes relayout of the volume 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 a concatenated volume, vol02, in disk group, mydg, to a striped volume with the default number of columns, 2, and default stripe unit size, 64 kilobytes:
# vxassist -g mydg relayout vol02 layout=stripe
On occasions, it may be necessary to perform a relayout on a plex rather than on a volume.
