words, whether to slow delay response to hosts).
• Yes: Inflow is restricted.
• No: Inflow is not restricted.
NOTE: If you select Yes and the metadata or journal data is full, update I/Os might stop.

data are full. This value must be within the range of 0 to 600 seconds.
NOTE: Currently, the value of Data Overflow Watch is predefined and cannot be changed. If
Inflow Control is No, Data Overflow Watch does not take effect and does not display anything.
• Copy Pace: Pace (speed) for an initial copy activity for one volume. The default is Low.
• Low: Speed of initial copy activity is slower than Medium and High.
