SE-CL-L3 | Service Engine Cluster - Performance | |
SE-NODE-G2 | Service Node |
Defect ID | Headline |
CSCvv95897 | DCNM installer on SE wipes drive w/ encrypted and clear fs and certs on it. |
A limited number of Data Center Network Manager (DCNM) appliances as mentioned in affected product list shipped with Versions 11.3 and 11.4 will show a failure when you attempt to install the Nexus Dashboard.
The existing DCNM service engine appliances can be upgraded to Nexus Dashboard. Service engine appliances ship with a Trusted Platform Module (TPM) partition. Due to an installer bug in DCNM Versions 11.3 and 11.4, this partition was wiped during installation of these versions of DCNM on service engine appliances.
Affected service engine appliances will continue to function as expected if the service engine upgrade to Nexus Dashboard is not required.
Affected DCNM service engine appliances cannot upgrade to Nexus Dashboard. When you attempt to upgrade to Nexus Dashboard, the conversion will fail with an error message.
