NOTE: Typically, the second Fibre Channel HBA that is initialized during the POST is the
Fibre Channel HBA on the higher slot number. However, because this can change
depending on your server architecture, always check your specific system architecture first.
• Introduce one server model to the SAN at a time to ensure that the MSA retains its defaults;
that is, the front-right controller is the primary and the front-left controller is the secondary.
Then, introduce the next server model following the recommendations above. If there are
multiple failovers/failbacks on the MSA controllers, swap the Fibre Channel cables around at
the end where the servers are introduced to the SAN.
IMPORTANT: If the active HBA is not correctly configured in the server as described above,
server failover will not occur. If an active server has already failed and failover did not occur
to the passive server, shut down the passive server and cycle the power to ensure that the
MSA1500 is recognized. See "Powering off and powering on the MSA" on page 97 for
instructions.
