Scott, Did you look in the "z/VM Planning and Administration" manual? That particular manual is one is a key "Book of Knowledge" for z/VM sysprogs. Anyone making directory changed should be familiar with that section of the manual (actually, all z/VM sysprogs should be at least aware of its contents and use it as a reference).
See: http://publibz.boulder.ibm.com/epubs/pdf/hcsg0b31.pdf It states: DEVMaint authorizes the specified virtual machine to use DIAGNOSE code X'E4' with subcode X'02' and X'03' to get a full-pack overlay read/write minidisk of the volume on which the specified minidisk or cylinder/block resides. A user with this option is also authorized to execute any function protected by the DEVINFO and MAINTCCW options. For more information about DIAGNOSE code X'E4', see the z/VM: CP Programming Services book.

Some of you were very adamant about specifying the option DEVMAINT, especially to operators. Could someone please explain what the option does and who should have it? I went through our VM directories and that option is specified to a handful of users on each of our systems. I would like to get an understanding of the option before I start removing it.
