HP StorageWorks XP Remote Web Console Software - Manual (Page 178)

Status Change by MCU(Hold to Pending): The status of the data volume pair was changed from
Hold to Pending because of an operation from the primary storage system.
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.
• If a failure occurs with two or more data volume pairs at the same time, only up to two rows
showing "Suspend Pair(Failure)" or "Ready for Delta resync(Failure)" will be displayed.
• The copy time might not be displayed in the Copy Time column, even though Paircreate
Complete or Pairresync Complete is displayed in the Operation column. In such case, you can
confirm the copy time at the volume list in the Pair Operation window.
• Page: displays the number of current page and total number of pages. The display format of
Page is "the number of current page / total number of pages." If there is no history file, "-/-" is
displayed.
• Previous: The list displays up to a maximum of 16,384 operations at a time. If the number of
operations exceeds 16,384, the Previous and Next buttons allows you to display the remaining
operations. The Previous button allows you to display the previous 16,384 operations.
• Next: The list displays up to a maximum of 16,384 operations at a time. If the number of
operations exceeds 16,384, the Previous and Next buttons allows you to display the remaining
operations. The Next button allows you to display the next 16,384 operations.
