::Thanks for an illustration.  BTW, five is not "a half a dozen or more" but I suggest the five steps u have identified fit the three processes as follows 
 ::#Low-level formatting == Factory formatting of the disks. 
 ::#Partitioning == Definition of logical volume to the DASD subsytem AND Formatting of the volume with ICKDSF 
 ::#High-level formatting == Allocation of an ESDS ... AND Formatting of the zFS within the ESDS 
 ::I going to change ""steps"" to "processes" and change yr note accordingly.
