4. To be able to install onto the logical drive on the DS400 at least one port must
allow access for an initiator. The port used is A0. A1, B0 and B1 will be
deactivated for the first HBA.
Note: The array of the logical drive to boot from needs to be owned by
controller A. First HBA needs access to the first port(FC0) of the Controller
A. Outside of the TotalStorage DS400 the ports are named FC0 and FC1
on each controller. CLI use A0 for FC0 and A1 for FC1 of controller A and
B0 for FC0 and B1 for FC1 of controller B.
Basically every port and HBA can be used as long as the host can see
every logical drive only once during installation of Microsoft Windows.

5. Verify that only one port is enabled for only one HBA. Only port A0 allows
access for the first HBA.
The access of the initiators to the ports needs to be enabled after finishing the
installation of the operating system and the multipath driver.
