This software sets WWPN-based security settings on a device to form an access path. However, when the faulty part such as an adapter (controller) is replaced, the WWPN name may be changed because it is unique.
Devices whose WWPNs are changed when the faulty part such as an adapter (controller) is replaced:
All HBAs and LT230, etc.
Devices whose WWPNs are not changed when the faulty part such as an adapter (controller) is replaced:
The ETERNUS Disk storage system, LT270 and LT250, etc.
Operation can be performed as is if WWPNs are not changed. If WWPNs are changed because an adapter (controller) is replaced, security functions of the WWPNs constituting the access path must be changed to those of new WWPNs. This operation is defined as "access path inheritance" and it provides a function that automatically reconfigures the WWPN security settings managed by this software.
