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.

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.

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.
