switches. This value is incremented when any port changes state in that VSAN. The key counter (a 32-bit
value) is incremented when a FICON-related configuration is changed. Host programs can increment
this value at the start of the channel program and then perform operations on multiple ports. The director
history buffer keeps a log of which port address configuration was changed for each key-counter value.
The director history buffer provides a mechanism to determine the change in the port state from the
previous time when a value was contained in the key counter.
