Use of Cache: Indicates whether to store journal data in the restore journal group into the
cache.

Use: Journal data will be stored into the cache. 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.

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.

Delta resync Failure: Indicates the processing that would take place when delta resync operation
cannot be performed.

Entire: Whole data in primary data volume will be copied to secondary data volume
when delta resync operation cannot be performed.

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

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

One of the following is displayed: 256, 100, or 10.

The recommended setting values are as follows:

10 is recommended if the line speed is from 10 Mbps to 99 Mbps.

100 is recommended if the line speed is from 100 Mbps to 255 Mbps.

256 is recommended if the line speed is 256 Mbps and more.

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.
