Hi kmathieu

As per the HPE XP7 Continuous Access Journal Software User Guide (December 2021), it is not recommended to mix emulation types for P-VOL and S-VOL pairs in a Continuous Access Journal environment for the mainframe.

In section 1.1.1 "Continuous Access Journal software for mainframe", the guide states, "When using Continuous Access Journal software, the P-VOL, and the S-VOL must be of the same type of emulation, size, and protection level."

Additionally, in section 2.2.2 "Volume considerations for Continuous Access Journal", the guide notes, "CAJ supports consistency between P-VOLs and S-VOLs that have the same attributes, such as the same emulation type."

Therefore, it is recommended to use the same emulation type for P-VOL and S-VOL pairs in a Continuous Access Journal environment for the mainframe. Mixing emulation types may result in compatibility issues and impact system performance.

Hope this helps.!!!
