• Inflow Control: Indicates whether inflow of update I/Os to the journal volume is restricted (in

other words, whether to slow the delay response to hosts).

◦ Yes: Inflow is restricted.

◦ No: Inflow is not restricted.

NOTE: Inflow Control displays nothing if the journal group is a restore journal group.

• Data Overflow Watch (sec): Time (in seconds) for monitoring whether metadata and journal

data are full.

NOTE: Data Overflow Watch displays nothing when one of the following conditions is

satisfied:

◦ Inflow Control is No.

◦ The journal group is a restore journal group.

• Copy Pace: Pace for an initial copy activity for one volume: High, Medium, or Low.

NOTE:

◦ By default, the pace for an initial copy activity is Low.

◦ Copy Pace displays nothing if the journal group is a restore journal group.

• Use of Cache: Indicates whether journal data is stored in the restore journal group in cache.

Use: Journal data is stored in cache.◦

NOTE: When there is insufficient space in cache, journal data is also stored in the

journal volume.

◦ Not Use: Journal data is not stored in cache.

CAUTION: This setting does not take effect on master journal groups. However, if you

use the XP RAID Manager horctakeover command to change a master journal group

to a restore journal group, this setting takes affect on the journal group. If you set Use,

this setting only takes effect on the journal volumes of RAID-5 or RAID-6 that are in the

journal group. For external volumes, non-RAID-5 journal volumes, and non-RAID-6 journal

volumes, Use works the same as Not Use.

• Delta resync Failure: Processing that takes place when the delta resync operation cannot be

performed.

◦ Entire: All data in the primary data volume is copied to the secondary data volume when

the delta resync operation cannot be performed.

◦ None: No processing takes place when the delta resync operation cannot be performed.

Therefore, the secondary data volume is not updated.

• Speed of Line: Line speed of the data transfer. The unit is Mbps (megabits per second).

One of the following appears: 256, 100, or 10.

The recommended setting values are as follows:
