Path Addition and Reduction (HBA Addition and Reduction)
This section describes how to increase paths by adding HBAs, and decrease paths by removing HBAs.
Adding and reducing HBAs without server rebooting (PCI Hot Plug) is not supported.
Adding and reducing HBAs with server rebooting is the same procedure as adding and reducing cables with
server rebooting. Add or reduce HBAs at the same time that cables are being added or reduced.
