If the value of Maximum Initial Copy Activities is increased, the time for the initial copy
processing is shortened. However, the host operation may be affected because the write
processing to the tracks in which the copy operation is in progress is forced to wait.

Establishing the Relationship Between Primary and Secondary Storage
Systems (Add DKC)
The Add DKC window (see
) allows you to associate the primary storage
system and the secondary storage system, and also allows you to establish logical paths between
the two storage systems. Logical paths are used to connect the primary and secondary storage
systems. Both the primary storage system and the secondary storage system use logical paths to
communicate with each other.
One primary storage system can be associated with up to 64 secondary storage systems. Up to
eight logical paths can be configured between one primary storage system and one secondary
storage system. Therefore, one primary storage system can have up to 512 logical paths to
secondary storage systems.
To associate the primary and secondary storage systems, and then configure logical paths between
the two storage systems, both the primary storage system administrator and the secondary storage
system administrator must perform this operation.
1.
Make sure the remote copy connections and ports are properly configured. Also, get the serial
number for the remote storage system.
To get the serial number for the remote storage system, ask the administrator of the remote
storage system. The serial number appears in the Remote Web Console main window when
the Remote Web Console user logs in to the storage system.
2.
Ensure that the Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see the HP StorageWorks XP24000/XP20000
Remote Web Console User Guide.
3.
Ensure that the DKC Operation window is open (see
“DKC Operation Window” (page 130)
).
4.
In Display, select DKC.
5.
Select LDKC from the tree.
6.
Right-click the upper-right list, and then select DKC Operation and Add DKC.
7.
In theAdd DKC window (see
), enter the following:
•
The serial number of the remote storage system.
•
The LDKC number of the remote storage system. 00 appears when the remote storage
system is an XP12000/XP10000 Disk Array or USP V/VM.
•
The controller ID of the remote storage system (model name that indicates the model).
The controller ID for an XP24000/XP20000 Disk Array is 5.
•
The path group ID. The path group ID is within the range of 1-FF (hexadecimal). Up to
64 path group IDs can be registered per storage system.
Note: In the current version, the path group IDs always take the default values and cannot
be changed.
8.
In theAdd DKC window, select a primary storage system port and a remote storage system
port to configure a logical path.
9.
Select Option.
