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 the upgrade:
UnassociatedServers
Afteryou upgrade the Cisco UCS domain, the initial server association proceeds without configuration
errorswhether or not the local 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 the server 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 previous service profile.
Guidelines for Local Disk Configuration Policies Configured for RAIDNo Mixed HDDs and SSDs
Donot include HDDs and SSDs in a single RAID configuration.
Do Not Use the Any Configuration Mode on Servers with MegaRAID Storage Controllers
Ifa blade server or rack-mount server in a Cisco UCS domain includes a MegaRAID storage controller, do
notconfigure the local disk configuration policy in the service profile for that server with the Any
Configurationmode. If you use this mode for servers with a MegaRAID storage controller,the installer for
theoperating system cannot detect any local storage on the server.
Ifyou want to install an operating system on local storage on a server with a MegaRAID storage controller,
youmust configure the local disk configuration policy with a mode that creates a RAID LUN (RAID volume)
onthe server.
Server May Not Boot After RAID1 Cluster Migration if Any Configuration Mode Specified in Service Profile
AfterRAID1 clusters are migrated, you need to associate a service profile with the server. If the local disk
configurationpolicy in the service profile is configured with Any Configuration mode rather than RAID1,
theRAID LUN remains in "inactive" state during and after association. As a result, the server cannot boot.
