To configure Host Flags, the administrator must follow the hierarchical workflow of the Unisphere interface:

1. Context: First, the specific storage array must be selected from the system dashboard or selector to ensure the configuration applies to the correct appliance.
2. Navigation: Next, the user accesses the host management view by selecting Hosts from the main menu, followed by the Hosts object/option within that category.
3. Action: The Create button is clicked to launch the "Create Host" wizard.
4. Configuration: Finally, within the wizard (typically in the Initiator or Attributes step), the user clicks the Set Host Flags button. This opens the settings to override default port flags (e.g., enabling SC3 or SPC2 bits) required for the host's operating system.
