• 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.
• Blank: The current Use of Cache setting remains unchanged.
CAUTION:
This setting does not take effect on master journal groups. However, if you use the RAID Manager
XP horctakeover command to change a master journal group to a restore journal group, this
setting takes 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: Line speed of the data transfer. The unit is Mbps (megabits 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 you use the RAID Manager XP
horctakeover command to change a master journal group to a restore journal group, this setting
takes 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.
• Set: Applies settings in the pane to the Journal Operation pane ( Figure 48 ).
• Cancel: Cancels settings.
