vCenter Plug-in for Aria Automation Orchestrator cache issues

Products

• VMware Aria Suite

Issue/Introduction

A major plug-in cache issue has been resolved which may lead to inconsistent data leading to various errors being thrown after upgrading the Orchestrator to 8.18.1. Given that the cache is a core plug-in component the behavior of the plug-in may be inconsistent. Some of the cases may be related to:

• Creating/adding a SCSI controller/HDD disks
• ESXi hosts entering/exiting maintenance mode
• Cannot find items for given tokenId
• Some of the vCenter objects are undefined
• Delay in checking Power state of the VM or delay in configuration changes
• Any other unexpected behavior

Environment

VMware Aria Automation Orchestrator 8.16.x and higher 

Cause

Cache is out of sync with the vCenter server data.
