Error Handling

QuickLoop isolates faulty switches or ports by excluding them from the
initialization process. This minimizes of the impact of a faulty looplet or switch
on normal QuickLoop operations, and is particularly important for QuickLoops
that contain multiple looplets distributed across two switches.

Switch Level Errors

Switch level errors affect dual-switch QuickLoops, and include the following
conditions:

1. A public host accesses a device on Compaq QuickLoop by translative mode (phantom),
in the same way it accesses a private device attached to an FL_Port.
2. Devices connected to Compaq QuickLoop lose their public functions. FLOGIs sent by
these devices are dropped, forcing them back to a private loop attachment.
No switch with the configured partner switch's WWN can be found in the
fabric.
No response is received from the partner switch during the initial handshake.
Inconsistent responses are received from the partner switch.
Responses are not received in time during QuickLoop initialization.
