  • Element Management Node (mNode)
  • Hybrid Cloud Control (HCC)
  • Management Services 2.3 and above

Issue

When deploying or configuring Element mNode, one or more mNode or HCC functions experiences failures--often including connectivity-related errors--even after the underlying management network has been validated

For instance:

  • Name resolution fails for the mNode and/or containers
  • mNode collector fails to report cluster data to ActiveIQ  (AIQ)
    • AIQ container appears to fail to resolve hostnames
  • Compute and/or storage nodes aren't displayed in HCC
    • compute or storage nodes may have IP's that the mNode containers are also using
  • 'This site can't be reached' errors in HCC or Swagger
  • Initial mNode setup (/sf/packages/mnode/setup-mnode script) fails with 'could not reach API' error:

[config_util:1404] ERROR:Could not reach mNode API. Debug the issue or clean up the docker environment and try again.
