A masking view is a container of a storage group, a port group, and an initiator group, and makes the storage group visible to the host.

## Steps

2. Select Hosts > Masking View to open the Masking Views list view.
3. Select the masking view from the list and click Rename.
4. Type the new Name, and click OK.
   Masking view names must be unique from other masking views on the array and cannot exceed 64 characters. Only alphanumeric characters, underscores ( _ ), and (-) are allowed. Masking view names are case-insensitive.
