HP StorageWorks XP Remote Web Console Software - Manual (Page 151)

Group If an error occurs with this pair, all the pairs in the mirror where this pair belongs will be split.
Volume If an error occurs with this pair, only this pair will be split.
• Sync.: If the volume in the local storage system is a primary data volume, this column displays
progress of an initial copy operation.
If the volume in the local storage system is a secondary data volume, this column displays
information in the following ways:
• If the volume pair is not split, this column displays nothing.
• If the volume pair is split and therefore is in Suspend status, this column usually displays
synchronization rate (i.e., concordance rate) between the secondary data volume before
it became split and the secondary data volume after it became split. For example, the
synchronization rate (i.e., concordance rate) is 100 percent if the contents of the secondary
data volume are the same before and after the volume pair became split. Caution: If a
failure in the initial copy operation causes the volume pair to be split, this column displays
nothing. If a failure occurs in the initial copy operation, the Detailed Information window
( Figure 66 on page 160) displays the phrase "Initial copy failed."
• In the following cases, this column will be blank.
When the volume in the local storage system is neither a primary data volume nor a secondary
data volume.
When the status of the volume pair is Hold or Hlde.
• CLPR: Indicates the number and the name of the CLPR where the data volume belongs.
• Pair Copy Time: The time taken for the copy operation (from the start of the operation to
the end).
NOTE:
The time that is shown in Pair Copy Time differs from the time that is shown in Copy Time on
the History window.
To create a pair:
1. MCU receives a request to create a pair.
2. MCU receives a request to start the creating pair operation.
3. The creating pair operation is started according to the conditions of initial copy priority and
maximum initial copy activities.
Pair Copy Time on the Detailed Information dialog box shows the amount of time that has been
needed from step 3 to the completion of the creating pair operation (i.e., the progress of the
creating pair operation reaches 100%). Copy Time on the History window shows the amount of
time that has been needed from step 1 to the completion of the creating pair operation.
• Used Volume: Indicates the size of used volumes, and also indicates the licensed capacity. For
example, if 12.34 (15.0) (TB) is displayed, the licensed capacity for URz is 15.0 terabytes, and
12.34 terabytes of volumes are used.
NOTE:
If the licensed capacity is unlimited, the sized of used volume is not displayed.
• Total Pairs: Indicates the current total number of data volume pairs.
• Preview: Displays detailed information about operations that will occur when you click Apply.
• List: Displays changes that have been made in the window. When you change settings in the
window, the changes will be displayed in the Preview list before the changes are applied to
storage systems. If you are sure that information in the Preview is correct, select the Apply
button to apply the settings that you have made.
