The Change JNL Option window displays the following:
•Inflow Control: Allows you to specify whether to restrict inflow of update I/Os to the journal volume (in other words, whether to slow delay response to hosts).
Yes indicates inflow will be restricted. No indicates inflow will not be restricted.
Note: If Yes is selected and the metadata or the journal data is full, the update I/Os may stop.
•Data Overflow Watch: Allows you to specify the time (in seconds) for monitoring whether metadata and journal data are full. This value must be within the range of 0 to 600 seconds.
Note: If Inflow Control is No, Data Overflow Watch does not take effect and does not display anything.
•Copy Pace: Allows you to specify the pace (speed) for an initial copy activity for one volume. The default is Low.
–Low: The speed of the initial copy activity is slower than Medium and High.
