 Aria Automation / Orchestrator manual (CLI) cluster upgrade from earlier versions to 8.14.x+ may fail due to SSH configuration

https://knowledge.broadcom.com/external/article?articleNumber=315177


Products

VMware Aria Suite

Issue/Introduction

Symptoms:

  • The node which executes the upgrade may become split from the cluster
  • In the upgrade log, you may see warnings related to host keys:
    • @  WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!   @
    • IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
    • Someone could be eavesdropping on you right now (man-in-the-middle attack)!
    • It is also possible that a host key has just been changed.

 

Environment

  • Aria Automation 8.x

Cause

  • It may be due to non-standard sshd_config (_effective) or it may be more widely seen if KB 326133 is not applied before manual upgrades.
  • More testing is needed to decide that.

Resolution

This is a less common issue than KB 326063.

  1. Ensure System health is good for upgrade
  2. Apply KB 326063 if these files exist
  3. Apply also KB 326133

 

  • The key step from that KB are to enforce certain algorithms in /etc/ssh/sshd_config_effective (or sshd_config on older versions)
  • These are given as values to the options MACs and KexAlgorithms in that file.

 

Additional Information

Impact/Risks:

  • No impact. These are recommended changes.

Environment VMware vRealize Automation 8.x Cause This issue has been identified where the problem appears when a single column Multi Value Picker or Data Grid is used. Resolution This is a known issue. There is a workaround.  Workaround: As a workaround, try adding one empty column in the Multivalue picker without filling the options. So we can add one more column without filling the value which will be hidden(there is a button in the designer page that will hide the column). This way the end user will receive the same view.

  The Guardrails of Automation VMware Cloud Foundation (VCF) 9.0 has redefined private cloud automation. With full-stack automation powered by Ansible and orchestrated through vRealize Orchestrator (vRO), and version-controlled deployments driven by GitOps and CI/CD pipelines, teams can build infrastructure faster than ever.

This third and final installment in our automation series focuses on how to secure and govern multi-tenant environments in VCF 9.0 with role-based access control (RBAC) and layered identity management. VCF’s IAM Foundation VCF 9.x integrates tightly with enterprise identity providers, enabling organizations to define and assign roles using existing Active Directory (AD) groups.
