Issue/Introduction

After the TCA upgrade when you try to upgrade the cluster add-on you might hit this issue and get the error above.

Validate in the vCenter to confirm if in fact have the same network name on multiple segments spanning across DVS.

Environment

1.x, 2.x

Resolution

If your cluster was created on a TCA version before TCA 2.3, the network name format does not include the DVS name. And because of this same segment names that spans multiple DVSs will result in this error.

 Cluster created before TCA 2.3 will have this naming convention for network name:

 /Datacenter-Name/network/Segment-Name

 

Cluster created on TCA 2.3 and later have this naming convention for network name

/Datacenter-Name/network/DVS-Name/Segment-Name

 

In order to resolve this issue, you need to make unique segment names.

If this is not an option, engage Broadcom Support by opening up an SR so we can understand why the network segments cannot have unique names and hopefully help with some other work around.
