Issue/Introduction

Error "Failed to take backup of existing installation" occurs during EEM upgrade attempted directly from   <AutoSys ISO>/modules/EEM/

 

Environment

AutoSys Workload Automation

Cause

• The message seems to be coming after the installer attempts to stop the services and start
• CA Directory itechpoz  service would not start. In this specific case, EEM is in a two node HA configuration
• CA Directory itechpoz on the primary node fails to start
• There was a file,  itechpoz in the %DXHOME%\pid folder and it was 0 bytes.
• The presence file  %DXHOME%\pid\itechpoz  was causing CA Directory iTechpoz service not to start. That's the reason why EEM upgrade failed.

Resolution

• Remove the file %DXHOME%\pid\itechpoz   from the primary EEM server
• Start the CA Directory itechpoz service
• Re-run upgrade again
