Just to clarify, DEFINE STORAGE is where the virtual (guest) side is handled. Use of the STANDBY and RESERVED options on DEFINE STORAGE shoul d allow a z/OS guest to exploit dynamic storage reconfiguration.
SET STORAGE is for CP exploitation for dynamic memory upgrade (to increas e CP's real storage dynamically - we only allow adding, not removing, stora ge dynamically). Also, these enhancements are available only in z/VM 5.4.0 and above. - Bill Holder, z/VM Development, IBM Endicott On Tue, 10 Nov 2009 09:30:41 -0500, Alan Altmark <alan_altm...@us.ibm.com > wrote: >On Monday, 11/09/2009 at 08:51 EST, Anson <yeal_c...@yahoo.com.cn> wrote : > >> Does anyone know if the z/OS running under zVM can realize dynamic >storage >> reconfiguration by issuing 'CF STOR(xxx), ONLINE'?
