Issue/Introduction

Symptoms:
  • NSX is unavailable from the vSphere Web Client plug-in after taking a backup of NSX Manager with quiesced snapshot.
  • The NSX plug-in User Interface (UI) is reachable but the pages do not display content.
  • In the vmware.log file of the NSX Manager VM, you see entries similar to:

    2016-02-25T15:00:48.586Z| vmx| I120: SnapshotVMXTakeSnapshotComplete: Snapshot 0 failed: Failed to quiesce the virtual machine (31).

    Note: The preceding log excerpts are only examples. Date, time, and environmental variables may vary depending on your environment.


Environment

VMware NSX for vSphere 6.2.x
VMware NSX for vSphere 6.3.x

Cause

This issue occurs due to a scheduled backup run by a third-party that leverages quiesced snapshots. This causes the NSX Manager to become unresponsive through the vSphere Web Client.

Resolution

To avoid this issue, VMware recommends you to follow these best practices when taking a backup of the NSX Manager:

Note: Backup/restore functionality provided by NSX is the only supported way to backup/restore the NSX Manager. VMware does not currently test or support any third party tool that takes snapshot of the NSX Manager.
