Sync.: If the volume in the local storage system is a primary data volume, this column shows
the 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
the synchronization rate (that is, 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 (that is, 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 (
“Detailed Information Window” (page 192) ) shows the message
Initial copy failed . In the following cases, this column will be blank.
During the initial copying, the data of the control cylinder is also copied. The data of the
control cylinder will be copied after the user data of each data volume is copied. While
the data of the control cylinder is being copied, this column shows 99%. Copying of the
control cylinder data will be finished in few seconds or few minutes at most, and then the
display of the column changes to 100%. 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: 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). 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 paircreate operation.
3. The paircreate operation is started according to the conditions of the initial copy
priority and maximum initial copy activities.
Pair Copy Time shows the amount of time needed from step 3 to the completion of the
paircreate operation (that is, the progress of the paircreate 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 paircreate operation.

VOL: Identifies the volumes in the local storage system.
A device ID ending in # (for example, 00:00:3C#), indicates the LDEV is an external volume.
For detailed information about external volumes, see the HP XP24000/XP20000 External
Storage Software User's Guide.
To the right of the icon is the LDKC number, the CU image number and the LDEV number of
the volume. The CU image number is located on the left of the colon. The LDEV number is
located on the right of the colon.
The icons are:
This volume not paired with any other volume. This volume is neither a primary data volume
nor a secondary data volume.
This volume is a primary data volume.
