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 Resume Pair Complete operations.
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.
