Hitachi Universal Replicator for IBM /OS User’s Guide
• JNL Group(LDKC): Indicates the number of a journal group and the LDKC
number. The LDKC number is enclosed in the parentheses following the
serial number.
• Attribute: Indicates the attribute of the journal group. When one journal
group uses multiple mirror IDs, Attribute indicates the attribute of the
data volume in the journal group whose mirror ID is not Hold or
Hold(Failure).
Initial A journal group in initial status.
Journal volumes are registered in this journal group, but no data volumes (primary data volumes
nor secondary data volumes) are registered in this journal group.
Master A master journal group.
Journal volumes and primary data volumes are registered in this journal group.
Restore A restore journal group.
Journal volumes and secondary data volumes are registered in this journal group.
Blank Neither journal volumes nor data volumes are registered in this journal group.
• JNL Volumes: Indicates the number of journal volumes registered in the
journal group.
• JNL Capacity: Indicates the total capacity of all the registered journal
volumes. The unit is cylinders for mainframe volumes. The unit is gigabytes
for open-systems volumes.
• 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.
Note: 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.
