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.

per second).
You can specify one of the following: 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 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. The default is Entire.

Therefore, the secondary data volume will not be updated.
