4 Sharing Continuous Access Synchronous Z volumes
This chapter helps you plan Continuous Access Synchronous Z pair volumes when they are shared
with non-Continuous Access Synchronous Z volumes. It discusses all of the program products that
can be used with Continuous Access Synchronous Z.
Volume types that can be shared with Continuous Access Synchronous Z
The following table indicates whether non-Continuous Access Synchronous Z volumes can also be
used as Continuous Access Synchronous Z M-VOLs and R-VOLs.
