Figure 53 JNL Group Detail pane
• JNL Group: Journal group's number.
• Attribute: Journal group's attribute. When the 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: Journal group in initial status. Journal volumes are registered in this journal group,
but no data volumes (primary or secondary data volumes) are registered in this journal
group.
◦ Master: Master journal group. Journal groups and primary data volumes are registered
in this journal group.
◦ Restore: Restore journal group. Journal groups and secondary data volumes are registered
in this journal group.
◦ Blank: No journal volumes and data volumes are registered in this journal group.
• JNL Volumes: Number of journal volumes registered in the journal group.
• JNL Capacity: Total capacity of all registered journal volumes.
• Data Volumes: Number of data volumes associated with the journal group. When one journal
group uses multiple mirror IDs, Data Volumes indicates the number of data volumes in the
journal group whose mirror ID is not Hold or Hold(Failure).
• Data Capacity: Total capacity of all data volumes. When one journal group uses multiple
mirror IDs, Data Capacity indicates the number of data volumes in the journal group whose
mirror ID is not Hold or Hold(Failure).
• Meta/Data Ratio: Ratio of metadata area to journal data area. For example, if 16 appears,
the ratio of metadata area to journal data area is 1:16. If 32 appears, the ratio of metadata
area to journal data area is 1:32.
• Extent: Number of extents.
