NOTE:

When there is insufficient space in the cache, journal data will also be stored

into the journal volume.

◦

Not Use: Journal data will not be stored into the cache.

◦

Blank: The current setting of Use of Cache will remain unchanged.

CAUTION:

This setting does not take effect on master journal groups. However, if the Business

Continuity Manager YKRESYNC REVERSE command is used to change a master journal group
into a restore journal group, this setting will take effect 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.

•

Speed of Line: Allows you to specify the line speed of data transfer. The unit is Mbps (megabits
per second).

You can specify one of the following settings: 256, 100, or 10.

CAUTION:

This setting does not take effect on master journal groups. However, if the Business

Continuity Manager YKRESYNC REVERSE command is used to change a master journal group
into a restore journal group, this setting will take effect on the journal group.

•

Delta resync Failure: Allows you to specify the processing that will take place when the delta
resync operations are initiated but cannot be performed.

◦

Entire: Whole data in the primary data volume is copied to the secondary data volume
when the delta resync operation cannot be performed. The default is Entire.

◦

None: No processing takes place when the delta resync operation cannot be performed.
Therefore, the secondary data volume is not updated.

CAUTION:

This option cannot be specified in the secondary site.

•

System: The system clock of the mainframe host is used.

◦

◦

Local: The system clock is not used.

◦

None: The system clock of the mainframe host is used. The difference between System
and None is explained in

“Timer Type Option” (page 27)

.

NOTE:

◦

Ensure that the same timer type is specified in both the primary and the secondary sites.

◦

Do not change the Timer Type if At-Time Split function is used when Universal Replicator
for Mainframe and ShadowImage for Mainframe are used in conjunction

◦

You can only specify System if the journal group belongs to an extended consistency
group.

When you use Fujitsu OS, select Local in Timer Type.
