Mainframe Enablers TimeFinder SnapVX and zDP 8.5 Product Guide

zDP requirements and limitations are as follows:

• zDP must be APF-authorized and access to output datasets should be limited to authorized personnel.
• For remote requests, the final destination storage system must be running PowerMaxOS 5978 or HYPERMAX OS 5977, while other storage systems in the hoplist may be Enginuity 5876.
• A source volume may not be in two active versioned data groups (VDG).
• All devices must be in the same SRDF mode to allow for consistency.
• A VDG cannot include SRDF/A devices that belong to different MSC groups.
• Devices in adaptive copy mode can be added to a zDP configuration, but zDP does not run with ADCOPY devices when consistency is enabled.
• Soft-fenced devices, dummy devices, guest operating system devices, and BCV devices are not supported.
• Virtual volume (vVol) devices cannot be added to a VDG or a target set.
• zDP operations are blocked if a Transparent Cloud Tiering (TCT) session is active on the requested device.
• When running multiple VDGs, only one VDG can perform its first cycle at a time.
