Figure 45 Edit Policy Dialog Box
The Edit Policy dialog box consists of:
• Pattern: Mapping policies. Default Policy is prepared.
• Policy: The content of the selected mapping policy is displayed.
• Emulation Type: The emulation type of the external volume set when it was mapped. To
select an emulation type other than OPEN-V, select the Except OPEN-V check box and select
the emulation type from the drop-down list.
• CLPR: CLPR used for accessing to the mapped volume when the cache memory is partitioned
using Disk/Cache Partition.
• SLPR: SLPR that the selected CLPR belongs to. However, when the emulation type for the
mainframe is selected in Emulation Type, you can only select CLPR that belongs to SLPR
number 0.
• Cache mode: displays if the write I/O from the host is propagated synchronously (Disable)
or asynchronously (Enable) to the external storage device.
• Inflow Control: displays the writing operation to the cache memory is stopped (Enable) or
continued (Disable) when the writing operation to the external volume is impossible.
• Number of LDEVs: maximum number of LDEVs to be created in the external volume.
• Auto Discovery of Ports: displays whether to search for the WWN connected to all the
external ports (Enable) or to search for the WWN connected to only the external port which
you specify (Disable). If you set Enable, Port Discovery is automatically executed before the
Configure Cross-subsystem Paths dialog box is displayed.
• Close button
Close the Edit Policy dialog box.
• Pop-up menu
The Edit Policy dialog box does not have a pop-up menu that can be displayed.
Deleting the External Volume Mapping
You can start the operation of deleting the external volume mapping from the Volume Operation window.
To delete the mapping of the external volume, click the Delete Volume command in the pop-up menu
displayed in the Volume Operation window. Though you can delete the setting of mapping for an
internal volume and an external volume using the Delete Volume command, you cannot delete data in the
external volume. You cannot delete data in the internal volume either.
You need to check the following before deleting the external volume mapping.
• Whether the execution of any application (for example, RAID Manager) that is using the
command device is in progress or not.
If the execution of any application that is using the command device is in progress, stop the
application.
• Whether the Disconnect Subsystem command or the Disconnect Volume command is executed.
