Comments
Support has been added to enable guest and host recognition and exploitation of Extent Space Efficient Thin Provisioned volumes. The following new features for these ESE devices are now available: 1) Pool space events (space warning, out of space, space constraint relieved) are now reported to OPERATOR. 2) The new RELSPACE command to return disk space back to the pool. 3) Query command enhancements to indicate a devices ESE support and to check pool space usage. 4) Unlike Track Space Efficient (TSE) devices, ESE volumes can contain CPOWNED and System Resident space once the device is fully provisioned. 5) Flashcopy commands updated to release allocated space when full volume extents are withdrawn. 6) Simulation of ESE related I/O commands for guest dedicated disks and full pack and 1-END minidisks. ---------------------------------------------------------------- This PTF should be applied along with PTF UV99329 for the related DirMaint APAR VM66108. ---------------------------------------------------------------- THE FOLLOWING CHANGES HAVE BEEN MADE TO THE SYSTEM REFERENCE LIBRARIES: ***START PUBLICATION CHANGE************************************* PUBLICATION TITLE: CP Commands and Utilities Reference RELEASE: z/VM 6.4 ORDER NUMBER: SC24-6175-12 ------------------------------------------- ABSTRACT: Changes to commands affected by z-Thin Provisioning BODY: New CP command RELSPACE.
