Sharing volumes with Continuous Access Synchronous
You can share both BC P-VOLs and S-VOLs with Cnt Ac-S P-VOLs and S-VOLs. However, you cannot
share only BC S-VOLs with Cnt Ac-S S-VOLs.
The write operation on the Cnt Ac-S P-VOL takes more time when you share a BC P-VOL with a
Cnt Ac-S S-VOL. This is especially true when the BC pair is in the process of being Quick Split
(“PSUS(SP)/PSUS” status) because the required BC pair copying time.
