•
Forward Path Watch Time: Specifies if the master journal group's Path Watch Time value is
forwarded to the restore journal group. If the Path Watch Time value is forwarded from the
master journal group to the restore journal group, the two journal groups have the same Path
Watch Time value.
◦
Yes: Path Watch Time value is forwarded to the restore journal group.
◦
No: Path Watch Time value is not forwarded to the restore journal group. No is the default.
◦
Blank: The current setting of Forward Path Watch Time remains unchanged.
CAUTION:
This option cannot be specified at the secondary site.
Select Yes at the primary site of the XP Continuous Access Journal pair for delta resync
operations because you must set the Path Watch Time in the secondary site to perform delta
resync operations.
•
Use of Cache: Specifies if journal data is stored in the restore journal group in cache.
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 XP RAID Manager
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 XP RAID Manager
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.
◦
None: No processing will take place when delta resync operation cannot be performed.
Therefore, the secondary data volume will not be updated.
•
Set: Applies settings in the pane to the Journal Operation pane (
).
•
Cancel: Cancels settings.
