• Data OverﬂowWatch(0to600sec): 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: 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.

• Medium: Speed of initial copy activity is faster than Low and slower than High.

To specify Medium, ensure that the amount of update I/Os (that is, write requests from hosts to

primary data volumes) is 10 MB/s or less per parity group. If it exceeds 10 MB/s, data volume

pairs might become split (suspended).

• High: Speed of initial copy activity is faster than Low and Medium.

To specify High, ensure that update I/Os (that is, write requests from hosts to primary data

volumes) do not occur. If update I/Os occur, data volume pairs might become split (suspended).

NOTE:

Secondary array administrators cannot specify this option.

• Unit of Path

Watch Time: Allows you to specify the unit of path watch time. You can specify

one of the following: minute, hour, or day.

• PathWatchTime(1to60min): Interval beginning when a path is blocked and ending when a

mirror is s

plit (suspended).

NOTE:

Ensure that the same interval is set for the master and restore journal groups in the same mirror

unless otherwise requested. If the interval differs between the master and restore journal groups,

these journal groups are not suspended simultaneously. For example, if the master journal group's

interval

is 5 minutes and the restore journal group's interval is 60 minutes, the master journal

group is s

uspended 5 minutes after a path is blocked and the restore journal group is suspended

60 minut

es after a path is blocked.

NOTE:

To split (suspend) a mirror immediately after a path is blocked, contact your HP account support

representative to set system option mode 448 to ON and set SVP mode 449 to OFF. For more

information about modes 448 and 449, see Table 30.
