Data Overflow Watch Sets number of seconds for the system to monitor write data to the journal volume, after the
journal volume threshold (80%) is reached.

Timer Type Sets the type of clock used for consistency time—System, Local, None.
Unit of Path Watch Sets unit of time for Path Watch Time—minute, hour, or day.
Time
Path Watch Time Specify the interval from when a path gets blocked to when a mirror gets split (suspended).
This value must be within the range of 1 to 59 minutes, 1 to 23 hours, or 1 to 30 days. You
can specify a numeric value in Path Watch Time.
Make sure that the same interval is set to both the master and restore journals in the same
mirror, unless otherwise required. If the interval differs between the master and restore journals,
these journals do not suspend simultaneously. For example, if the interval for the master journal
is 5 minutes and the interval for the restore journal is 60 minutes, the master journal suspends
in 5 minutes after a path gets blocked, and the restore journal suspends in 60 minutes after
a path gets blocked.
Important: If you want a mirror to get split (suspended) immediately after a path gets blocked,
ask HP Technical Support to set the system option mode 448 to ON and set the system option
mode 449 to OFF.
Forward Path Watch Forwards the Path Watch Time value for the master journal to the restore journal, which results
Time in the same Path Watch Time value for both.
Copy Pace Sets pace for initial copy—Slow, Medium, or Fast.
Transfer Speed Line speed of data transfer.
