•
The Remote DKC Control Function environment (route list definition and command device
registration) is defined.
To confirm this, check the definition in the Route Status panel, which is displayed from the
Manage Route panel.
For background information, see “Setting up the Remote DKC Control Function environment”
(page 127) .
•
When a Remote Scan is performed via a storage system, the disk configuration definition file
of that storage system is updated by the Remote Scan.
Although a disk configuration definition file is created for the storage system when a route list
is created, you need to perform a Remote Scan to update the disk configuration definition file.
The disk configuration definition file is updated by pressing the F3=Exit key in the Discover
Hitachi Storage System panel after a Remote Scan.
For example, in a 3DC Cascade (Cnt Ac-S Z x Cnt Ac-J Z) configuration, before performing
a Remote Scan of a storage system at the remote site, perform a Remote Scan of a storage
system at an intermediate site to update the disk configuration definition file.
NOTE: The disk configuration definition file acquired by a Remote Scan cannot be used in other
sites.
For example, if you use a Remote Scan from the Primary site to acquire a disk configuration
definition file at the Secondary site and then transfer it to the Secondary site, an error results if you
subsequently specify the file in either of the following:
•
The Local Device Address Domain ID field on the Set Defaults ISPF panel.
•
The DAD parameter for the YKLOAD command.
Specifying a Route List ID
Specify a route list ID in the Set Defaults panel before performing a Remote Scan.
•
Preset RouteListID: Provide the route list ID for the route from the Primary site to the Secondary
site.
NOTE: If no route list has been defined, you can suppress the display of the LOAD Option
panel (that otherwise would be displayed after route list creation) by specifying a pre-selected
route list name of up to eight characters in this field.
•
Preset Route Label: Specify a route label to be used.
•
Remote DKC Function: Indicate the use of the Remote DKC Control Function (type Y).
For the procedures for performing this operation, see “Specifying a Route List ID” (page 122) .
Performing a Remote Scan
Perform a remote scan from the Discover HP Storage System panel.
Assigning a Dummy Device Number
Device numbers (DEVNs), which are recognized by the host, are not assigned to the devices in
the device configuration information acquired by a remote scan because the information is not on
the storage system connected to the host. Therefore, when the remote scan completes, the CU
Selection List for Edit devn panel is displayed to allow you to assign a dummy device number for
each scanned device.
