Viewing Mapping View Information

Prerequisites

At least one mapping view has been created on the storage system.

Procedure

1. Log in to DeviceManager.
2. Choose Provisioning > Mapping View.
3. View the information about mapping views.
   Table 5-23 describes the related parameters.

   Table 5-23 Mapping view parameters

   Parameter	Description	Setting
   Name	Name of a mapping view.	[Example] MappingView001
   ID	ID of a mapping view.	[Example] 2
   vStore Name	Name of the vStore where the mapping view belongs.	[Example] --
   vStore ID	ID of the vStore where the mapping view belongs.	[Example] --

   GUIs may vary with product versions and models. The actual GUIs prevail.

4. Select a mapping view. On the LUN Group tab page in the lower part of the function pane, view the information about the LUNs and snapshots in the mapping view.
