Shock!
I suppose I would be in SHOCK too if I went to pure Linux anything after over 30 years of UNIX.
For years there has been talk of "generic" *NIX - and for many commands, generic works. However, "distributions" of *NIX, including Linux (which is usually lowercase, not upper case) all have there differences.
The little I know of Linux makes me doubt that Linux volume management has not gotten farther than the "divvy/fdisk" like ways that were common +- 12 years ago.
But they are different from using smit (as admin interface) or the *vg, *lv, *fs commands to make, change, remove volume groups, logical partitions, and file systems on AIX. Basically, every *NIX has there own way of doing the administration - and the "rosetta stone" approach is probably an excellent start for you own cheat-sheet.
