HP XP P9500 Storage - Manual (Page 20)

The following takes place when you run At-Time Split with shared Cnt Ac-J Z volumes:
1. Cnt Ac-J Z restore journal data created before the split time is restored to Cnt Ac-J Z S-VOLs
(BC Z P-VOLs).
2. Restore journal operations are suspended when Cnt Ac-J Z detects restore journal data with
a time stamp later than the split time. After the Cnt Ac-J Z suspension, the BC Z split operations
run.
3. When BC Z split operations are completed, Cnt Ac-J Z resumes the suspended restore journal
operations.
