4.6.7 How to recover when an error occurred in a transfer route at the execution of PHP

The following describes the recovery procedures from a failure occurred during NIC (PCI card) replacement operation with PHP.

[Fast switching mode]

See "4.6.1 Recovery procedure from line failure in Fast switching mode" as to how to recover when an error occurred in a transfer route in Fast switching mode.

[NIC switching mode]

While executing PHP, because HUB monitoring function and standby interface monitoring function stops while exchanging the NIC (PCI card), if a failure is detected in a transfer path, it suspends the network communication. After the transfer path recovers, the communication recovers as well, so no further recovery work is required. However, some application requires restarting the application.

[GS/SURE linkage mode]

See "4.6.5 Recovery procedure from line failure in GS/SURE linkage mode" as to how to recover when an error occurred in a transfer route in GS/SURE linkage mode.

As for RIP and Fast switching/RIP modes, there is no recovery procedure as PHP expansion/replacement mechanisms cannot be used in those modes.
