EXCTG: Indicates an extended consistency group number and an LDKC number that is enclosed
by parentheses. This number is a two-digit hexadecimal number.
•
Attribute: Indicates the attribute of an extended consistency group.
An extended consistency group in primary site (primary EXCTG).
An extended consistency group in secondary site (secondary EXCTG)
This column displays the word changing when all journal groups in an extended consistency
group are being registered.
•
C/T: Displays the consistency time of an extended consistency group. For example, if the
consistency time is 10:00 a.m., secondary data volumes in the extended consistency group
are synchronized with the primary data volumes that were available as of 10:00 a.m.
The consistency time is displayed in the following format:
month/date/year hour/minute/second
For the number of seconds, the number before and after the decimal point is displayed.
This column displays the phrase Time is not consistent if secondary volumes in active journal
groups in the extended consistency group do not have the same time stamp. For example,
when a new journal group is added to the extended consistency group, this column displays
Time is not consistent if the time stamp of a secondary data volume in this journal group is
newer than the time stamp of secondary data volumes in the existing journal groups.
To maintain data update sequence, URz performs arbitration processing on journal groups in
Active status only. URz does not perform arbitration processing on journal groups in Stop
status.
This column displays There is no time stamp for an extended journal group containing journal
groups, if an initial copy operation is performed when hosts do not issue any I/O request.
This column displays Underflow or Overflow if an invalid time stamp is detected. If Underflow
is displayed, the time stamp is below the allowable range. If Overflow is displayed, the time
stamp is above the allowable range.
•
Num of DKC: Indicates the number of storage systems registered in an extended consistency

•
Num of JNLG: Indicates the number of journal groups registered in an extended consistency
group.
