Units are divided between the host ports:
Units 0-99 are on host port 1 of both controllers (but accessible only through the active
port).
Units 100-199 are on host port 2 of both controllers (but accessible only through the
active port).
Transparent failover only compensates for a controller failure, and not for failures of either
the Fibre Channel link or host Fibre Channel adapters.
