On a multi-port I/O adapter, it is necessary to handle severe errors that are related to a single port, and be able to fence that port. This fencing of a port must allow operation to resume or continue on other ports of the adapter without noticeably affecting ongoing operations. Hardware associated with the fenced port must be reset and isolated from continued operations on other ports sharing the same adapter.
