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.

Caution:

journal group, this setting will take effect on the journal group.
