Enhance define volume command with additional parameter

When defining a Sequentialfilevolume, it appears instantly in the filesystem. This is possible, because the internal structure of the volume will be created later, when data is written to it. This was introduced somewhere in TSM Version 6.3 and usually it is a pretty thing because of speeding up the whole process.

If your Sequentialfilevolumes are residing on a Disksubsystem with Thin-Provisioned Diskpools, this can be critical. You might allocate far more space, than you actually have. While overprovisioning is always a thing that has to be handled carefully, with TSM and Spacereclamation you risk pretty fast an IO-Stop on the Disksubsystem because of Diskpool is full.

Therefore it would be helpful, if i can choose when the define command is creating the internal structure. Instantly, which needs obviously more time when volumes are defined, or later, when data is written to them.
