Upgrade fails with an error "Please contact GSS to retry the upgrade along with the image-mount error"

Products

• VMware NSX

Issue/Introduction

• A failure is observed specifically when executing an upgrade path from release 4.2.3 to any 4.2.3.X patch version.
• The preliminary checks returned clean results; no anomalies were detected.
• The upgrade process terminates unsuccessfully when reaching the Install_OS phase.
  

  Upgrade steps:
   download_os [****.****.****] SUCCESS
   shutdown_manager [****.****.****] SUCCESS
   install_os [****.****.****] FAILED

• The upgrade also throws an Image mount error while placing the image in desired folder.
  

Environment

• VMware NSX - 4.2.3.0

Cause

• The NSX Manager was unable to retrieve the expected file from the /image directory designated for NSX version files.

Resolution

Restart/resume upgrade from CLI when orchestrator UI is not accessible using the below steps:-

• Check which step failed in /var/log/resume-upgrade.log
• Run CLI command "get upgrade-bundle <bundle-name> playbook VMware-NSX-manager-<version>-playbook" to get list of steps in playbook of manager. Verify that the failed step is after the "reboot" step in sequence
• (Only on orchestrator node) Run the playbook again using CLI command "start upgrade-bundle <bundle-name> playbook VMware-NSX-manager-<version>-playbook". Since the failure is in post-reboot upgrade step, MP will not reboot again
• (Only on orchestrator node) Run CLI command "resume upgrade-bundle <bundle-name> playbook" to resume the upgrade.
• Check the upgrade process by running "get upgrade process-status"
