Failback
When a previously failed path is made
available once again, I/O traffic can
resume use of that path. In some cases,
the system begins using the original path
automatically (auto-failback). In other
cases, operator intervention is required to
allow the system to begin using the
original path (manual-failback).

In an active/passive configuration, the
term failback commonly refers to traffic
resuming the use of the primary paths,
instead of the secondary paths, which
requires that the primary paths be made
active.
