Defect Information

Problem Description

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.

Background

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.

Problem Symptom

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.

The error seen by the customer is shown here:

Workaround/Solution

In case the error message from the Problem Symptom section is seen and the serial number shows as impacted in the Serial Number Validation Tool, Cisco recommends to initiate a Return Material Authorization (RMA) replacement as part of the Fix on Fail process.

If SE-CL-L3 was purchased, replace it with three nodes of this Product ID (PID): SE-NODE-G2=.
