Sharing Thin Image volumes with Dynamic Provisioning and Dynamic Provisioning for Mainframe in a single storage system
If you are using Thin Image, Dynamic Provisioning, and HDPz in a single storage system, note the following when creating Thin Image pairs:
You can create a Thin Image pair whose P-VOL is a Dynamic Provisioning V-VOL only if you are not currently expanding the Dynamic Provisioning V-VOL capacity.
Performing a Thin Image paircreate operation while zero pages are being reclaimed (including reclamation by Writesame, Unmap command, or rebalancing) results in the zero-page operation being interrupted.
Thin Image pair creation might be rejected if the Unmap command operation is in progress with system option mode 905 ON. Wait a while and then retry the operation. If the operation still fails, set system option mode 905 to OFF and try again.
You can use a maximum size Dynamic Provisioning volume as a Thin Image P-VOL. For information about the maximum size for Dynamic Provisioning volumes, see the Provisioning Guide for your storage system.
