Converting Virtual Volumes
Converting virtual volumes from one type of provisioning to another allows you to balance space
savings and cost. You can save storage space by converting little-used volumes to Thin volumes.
Costs can be reduced by converting fully allocated volumes to Full volumes. Volumes can remain
online and continue I/O operations during the conversion process.

convert Thinly Provisioned volumes to Fully Provisioned and Fully Provisioned volumes to Thinly
provisioned.
