Expand luns in Clariion

Not sure about new Flare, a lun can only be expanded for a maximum of eight times in Flare 19 or earlier. Besides, there are limitation as well. The component(s) has to be the same size as the source lun. For example, you have a lun of 10 GB and want to expand it to 30 GB. You will need to create 2 luns of 10 GB first (you cannot add a 20 GB lun as component to a 10 GB source lun), then expand the lun. Of course, lun expansion in EVA is different.

A caution: if you use existing lun as component(s), make sure you don't need the data in those components. Data in the component will be destroyed right away if stripping is chosen.
