Status Change by MCU(Hold to Simplex): The status of the data
volume pair was changed from Hold to Simplex because of an operation
from the primary storage system.
Status Change by RCU(Hold to Simplex, Delete Pair Start): An
operation for releasing a pair has been started at the secondary storage
system. The status of the data volume pair will change from Hold to
Simplex.
Status Change to Hold: The status of the secondary data volume was
changed to Hold because of a delta resync operation.
Unknown: The storage system could not identify the type of the
operation.
– JNL Group: The journal group number.
– Mirror ID: The mirror ID.
– VOL: The volume manipulated during the operation. This volume is
located in the local storage system.
The number to the left of the colon (:) is the CU number. The number
to the right of the colon is the LDEV number.
– Paired VOL: The volume paired with the manipulated volume. This
volume is located in the remote storage system.
The number to the left of the colon (:) is the CU number. The number
to the right of the colon is the LDEV number.
– EXCTG: The extended consistency group number. This column is blank
if the volume does not belong to any extended consistency group. If the
Business Continuity Manager YKMAKE command was used to create a
pair, this column may not display the extended consistency group
number.
– Copy Time: The time taken for the operation (from the start of the
operation to the end). Displayed only for Add Pair Complete and

Notes:
– The history information (i.e., rows in the list) might not be displayed in
chronological descending order. To sort the information in descending
(or ascending) order, click a header of the list.
– The History window can display history information of up to 524,288
operations. However, the window can only display up to 16,384
operations at one time. To display the remaining operations, click the
Previous or Next button.
– The History window does not display history information older than
seven days. Also, if the number of operations exceeds 524,288, the
oldest operations are deleted in chronological order to keep the number
at 65,535, even if the operations occurred within the last week. The
history file always contains the most recent operations up to a
maximum of 65,535 operations. The history information for an entire
week may not always be available.
