Adapter Card Considerations
Decommission/Recommission When Adding, Removing, or Replacing an Adapter Card
When you add, remove, or replace an adapter card in a UCS-managed server, you must first 
decommission the server in Cisco UCS Manager. After the operation, you must then recommission the 
server.
vNIC/vHBA Priority When Two Cisco UCS P81E VIC Adapter Cards Are Installed
If an integrated server contains two Cisco UCS P81E Virtual Interface Cards, the vNICs/vHBAs on 
Adapter 1 might have a higher PCI order in Cisco UCS Manager than the vNICs/vHBAs on Adapter
 2.
Re-acknowledge After Changing SR-IOV/ARI Bus Reservation BIOS Settings
In the C-Series BIOS version 1.4(3c) and later, there is an option by which you can enable or disable 
SR-IOV/ARI (single-root I/O virtualization/alternative routing-ID interpretation) bus reservation. 
Whenever you change the SR-IOV/ARI bus reservation settings on a UCS-managed server, you must 
re-acknowledge the server.
FEX Considerations
Re-acknowledge Attached Servers After a 2232 FEX Is Decommissioned/Recommissioned
Whenever you decommission or recommission a Cisco UCS 2232 FEX, all the servers that are connected 
to that FEX must be re-acknowledged in UCS Manager.
