–If the volume pair is split and therefore is in Suspend status, Sync. 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, Sync. displays nothing. If a failure occurs in the initial copy operation, the Detailed Information window (Figure
–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.
•
The first line displays the LDKC number, the CU number and the LDEV number of the primary data volume. If the primary data volume exists in the local storage system, the first line also displays the CLPR number and the CLPR name.
The second line displays the device emulation type. The third line displays the volume capacity.
Note: If a volume is an external volume, the symbol "#" appears after the LDEV number. For detailed information about external volumes, please refer to the Universal Volume Manager User's Guide.
Note: If a volume is a volume of TagmaStore USP/NSC, “00” is displayed as the LDKC number.
