Sharing volumes in a 3-Cnt Ac-J DC cascade configuration
You can share BC volumes with Cnt Ac-J volumes in 3 DC cascade configurations. You can share
BC P-VOL and S-VOLs with Cnt Ac-J volumes, as shown in the following figure.

When associated with these configurations, BC pair operations are dependent on the pair status
of the Cnt Ac-J local-intermediate pair and the local-remote pair.
The following table shows the BC operations that you can perform when the P-VOL is shared with
