Appendix
Integration With Cisco UCS Manager 2.0(2 xx ) and Later
This section contains two procedures:
•
Integrating a Release 1.4(3c) or Later Server With Cisco UCS Manager 2.0(2xx), page D-2
• Upgrading a Server Earlier Than Release 1.4(3c) for Cisco UCS Manager 2.0(2) Integration,
page D-6
Integrating a Release 1.4(3c) or Later Server With Cisco UCS Manager 2.0(2 xx )
Servers that are at CIMC release 1.4(3c) or later already have the prerequisite firmware and settings so
that they are ready to be connected to the Cisco UCS environment immediately. If your server is at a
CIMC release earlier than 1.4(3c), you must upgrade it as described in
Upgrading a Server Earlier Than
Release 1.4(3c) for Cisco UCS Manager 2.0(2) Integration, page D-6 .

Hard-Pinning Mode and Port-Channel Mode Discovery Policies
In the configuration described in this procedure, the FEXes can be connected to the FIs in two ways. You
have the option to choose either of two modes as your FEX discovery policy in Cisco UCS Manager.
1.
Hard-pinning mode —In this mode, the server-facing ports of the FEX are pinned to the connected
uplink ports as soon as the FEX is discovered. The Cisco UCS Manager software pins the
server-facing ports to the uplink ports based on the number of uplink ports that are acknowledged.
If a new uplink is connected later or if an existing uplink is deleted, you must manually acknowledge
the FEX again to make the changes take effect.
2.
Port-channel mode —In this mode, all uplink ports are members of a single port-channel that acts
as the uplink to all server-facing ports. There is no pinning. If a port-channel member goes down,
traffic is automatically distributed to another member.
The Cisco UCS 6200 Series FI has six sets of eight contiguous ports, with each set of ports managed
by a single chip (see
Figure D-1 ).
When you cable between the FEX and the FI in port-channel mode, the available virtual interface
(VIF) namespace varies, depending on where the uplinks are connected to the FI ports:
–
When port-channel uplinks from the FEX are connected only within a set of eight ports
managed by a single chip, Cisco UCS Manager maximizes the number of VIFs used in service
profiles deployed on the servers.
–
If uplink connections are distributed across ports managed by separate chips, the VIF count is
decreased. For example (see
Figure D-1 ), if you connect seven members of the port channel to
ports 1–7, but the eighth member to port 9, this port channel can only support VIFs as though
it had one member.
