What will happen to the data of a compressed volume if I decided later on to uncompress the volume? Will it remain compress at the storage level?

Re: V7000 Compressed Volumes2012-11-05T17:46:18Z in response to XSeriesxpertYou don't so much "convert" a volume, rather you add an extra copy to the volume (of any type: compressed, space-efficient, fully-allocated, image mode, etc) then remove the original copy.
This means you can decide to uncompress the data for a volume at a later date, for example if you aren't getting the compression savings or performance that you were looking for, and you can do the conversion between volume types (add/sync/remove copies) non-disruptively.
