Sorry, the answer is YES if one has not defined reserved storage. At partition activation the storage is assigned in contiguous segments.

Thomas Ambros Operating Systems and Connectivity Engineering 518-436-6433 From: Tom Ambros <thomas_amb...@keybank.com> To: IBM-MAIN@LISTSERV.UA.EDU Date: 07/11/2013 09:20 Subject: Central Storage reallocation on z9 - requirement to be contiguous? Sent by: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> z9 with three partitions, activated in order A, B, C. No reserved storage defined. We need to remove some storage from C and assign it to A. Without any operations on B, can we deactivate C, reduce initial storage, reactivate it and then deactivate A later that night, increase initial storage and reactivate it successfully? I do not see any mention of a requirement for contiguous storage in the z9 Tech Guide, it says only that the storage can come from any unused storage or storage released from another partition.
