Black pipes between containers, but within container the connections look fine

Products

• Spectrum
• Network Observability

Issue/Introduction

We recently manually modeled a number of connections, and some of these ended up as "black" pipes to some Containers. Within the Container we see proper yellow or green pipe connections. The black pipes only exist on Universe Topology. 

Environment

Spectrum Core / SpectroSERVER: any supported release

Cause

The connections are most likely correct.

Black pipes happen every now and again if Spectrum intelligence doesn’t calculate the peer link properly.

Resolution

• Save the SSdb
  
  
• Run the CLEANUP_ALL_CONTAINERS_LINK_LIST = 0x10900 in VNMSH CLI
  
  update action=0x10900 mh=<VNM_MH>
  
  
• If the action code doesn’t work, try cutting all models in the container, then paste them back in.
