•
Data Volumes: Indicates the number of data volumes associated with the journal group. When
one journal group uses multiple mirror IDs, Data Volumes indicates the number of the data
volumes in the journal group whose mirror ID is not Hold or Hold(Failure).
•
Data Capacity: Indicates the total capacity of all the data volumes. The capacity is expressed
in cylinders and gigabytes. When one journal group uses multiple mirror IDs, Data Capacity
indicates the total capacity of the data volumes in the journal group whose mirror ID is not
Hold or Hold(Failure).
•
Inflow Control: Indicates whether to restrict inflow of update I/Os to the journal volume (in other
words, whether to slow delay response to hosts).
Yes indicates inflow will be restricted. No indicates inflow will not be restricted.
•
Data Overflow Watch: Indicates the time (in seconds) for monitoring whether metadata and
journal data are full.
Data Overflow Watch displays nothing when one of the following conditions is satisfied:
• Inflow Control is No.
• Copy Pace: Indicates the pace for an initial copy activity for one volume.
One of the following is displayed: High, Medium, or Low.
Notes:
• By default, the pace for an initial copy activity is Low.
• Copy Pace displays nothing if the journal group is a restore journal group.
•
Use of Cache: Indicates whether to store journal data in the restore journal group into the cache.
• Use: Journal data will be stored into the cache. 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.
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.
•
Delta resync Failure: Indicates 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.
• None: No processing will take place when delta resync operation cannot be performed.
Therefore, the secondary data volume will not be updated.
•
Speed of Line: Indicates the line speed of data transfer. The unit is Mbps (megabits per second).
One of the following is displayed: 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.
•
Timer Type: Indicates 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 “
•
EXCTG, DKC/CTRLID: Displays the following information sequentially if the journal group belongs
to an extended consistency group:
• the extended consistency group number
• the serial number and the LDKC number (the LDKC number is enclosed by parentheses)
• A
slash
(/),
the
controller
