is forwarded from the master journal group to the restore journal group, the two journal groups
will have the same Path Watch Time value.
◦
Yes: The Path Watch Time value will be forwarded to the restore journal group.
◦
No: The Path Watch Time value will not be forwarded to the restore journal group. No
is the default.
◦
Blank: The current setting of Forward Path Watch Time will remain unchanged.
CAUTION:
This option cannot be specified in the secondary site. Select Yes in the primary
site of URz pair for delta resync operation since you need to set path watch time in the
secondary site to perform delta resync operation.
•
Use of Cache: Allows you to specify whether to store journal data in the restore journal group
into the cache.
◦
Use: Journal data will be stored into the cache.
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.
•
Speed of Line: Allows you to specify the line speed of data transfer. The unit is Mbps (megabits
per second).
You can specify one of the following settings: 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.
◦
None: No processing will take place when delta resync operation cannot be performed.
Therefore, the secondary data volume will not be updated.
CAUTION:
This option cannot be specified in the secondary site.
•
Timer Type: Allows you to specify the type of clock used for consistency time.
System: The system clock of the mainframe host is used.
◦
◦
Local: The system clock is not used.
◦
None: The system clock of the mainframe host is used. The difference between System
and None is explained in
