Description Item
Restrict inflow of update data to the journal volume. Yes restricts inflow, No does not restrict
(slows delay response to hosts). Inflow Control
Sets number of seconds for the system to monitor write data to the journal volume, after the
journal volume threshold (80%) is reached. Data Overflow Watch is blank when Inflow Control
is No. Data Overflow Watch
Stores journal data in cache memory from the restore journal (only). Use of Cache
Sets the type of clock used for consistency time—System, Local, None. Timer Type
Sets unit of time for Path Watch Time—minute, hour, or day. Unit of Path Watch
Time
The interval from when a path gets blocked to when a mirror gets split (suspended). Path Watch Time (1 to
59 min, 1 to 23 hour,
1 to 30 day)
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 system option 448 to ON and set system option 449 to OFF.
Forwards the Path Watch Time value for the master journal to the restore journal, which results
in the same Path Watch Time value for both. Forward Path Watch
