• 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 “Timer Type Option” on page 31.

• 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 ID
