All Connectivity May Be Lost During Upgrades if vNIC Failover and NIC Teaming Are Both Enabled
Allconnectivity may be lost during firmware upgrades if you have configured both Enable Failover on one
ormore vNICs and you have also configured NIC teaming/bonding at the host operating system level. Please
designfor availabilityby using one or the other method, but never both.
Todetermine whether you have enabled failover for one or more vNICs in a Cisco UCS domain, verify the
configurationof thevNICs withineach service profile associatedwith a server.For more information, see
theCisco UCS Managerconfiguration guide forthe releasethat you are running.
Impact of Upgrade from a Release Prior to Release 1.3(1i)
Anupgrade from an earlier Cisco UCS firmware release to release 1.3(1i) orhigher has the following impact
onthe Protect Configuration property of the local disk configuration policy the first time servers are associated
withservice profiles after theupgrade:
UnassociatedServers
Afteryou upgrade the Cisco UCS domain, the initial server association proceeds without configuration
errorswhether or not thelocal disk configuration policy matches the server hardware. Even if you
enablethe Protect Configuration property, Cisco UCS does not protect the user data on the server if
thereare configuration mismatches between the local disk configuration policy on the previous service
profileand the policy in the new service profile.
Ifyou enable the Protect Configuration property and the local disk configuration
policyencounters mismatches between the previous service profile and the
newservice profile, all subsequent service profile associations with the server
areblocked.
Note
AssociatedServers
Anyservers that are already associated with service profiles do not reboot after the upgrade. Cisco UCS
Managerdoes not report any configuration errors if there is a mismatch between the local disk
configurationpolicy and theserver hardware.
Whena service profile is disassociated from a server and a new service profile associated, the setting
forthe Protect Configuration property in the new service profile takes precedence and overwrites the
settingin the previousservice profile.
