Data Protector for z Systems (zDP) is a Dell EMC z/OS-based application that uses TimeFinder SnapVX snapshots to enable rapid recovery from logical data corruption. zDP achieves this by providing multiple, frequent, and consistent point-in-time copies of data in an automated fashion across multiple volumes from which an application level recovery can be conducted.
For more information about zDP see the Data Protector for Z Systems (zDP) Essentials White Paper.
Solutions Enabler and Unisphere can display snapshots that were created by zDP but cannot perform control operations on those snapshots.
PowerMaxOS 5978 Q3 2019 SR increased the zDP snapshot limit from 256 to 1024 snapshots per source volume. Solutions Enabler 9.1, Unisphere 9.1, and REST API 9.1 can report each of those snapshots.
However, versions of management software before 9.1 do not have the ability to report more than 256 snapshots per source volume. If a volume has any zDP snapshots that were created with PowerMaxOS 5978 Q3 2019 SR, a single placeholder snapshot with the name _Automated_Snapshot will be displayed for the volume as seen in the following example.
