– To display extended consistency groups in which no journal group is

Figure 4-13 Extended Consistency Groups in the EXCTG Operation
Window
• 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.
Note: 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.
