Chapter 6 Configuring Journal Groups

6-13

Hitachi Universal Replicator for IBM /OS User’s Guide

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.

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.

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 section Timer Type Option.

EXCTG, DKC/CTRLID: Displays the following information sequentially if

the journal group belongs to an extended consistency group:

the serial number and the LDKC number (the LDKC number is enclosed
by parentheses)
