HPE Smart Update Tools (SUT) service fails to start after upgrading to ESXi 8.0 on HPE servers

Products

• VMware vSphere ESXi 8.0

Issue/Introduction

In HPE server environments upgraded from ESXi 7.0 Update 1 to ESXi 8.0 Update 3 using an HPE Custom Image, the following symptoms occur:

• After the ESXi host boots, the HPE SUT (Smart Update Tools) service remains in a stopped state.
  
  
• The service might be displayed as "Running" in the vSphere Client GUI, but checking the status via the ESXi CLI (/etc/init.d/sut status) indicates that the service is stopped.
  
  
• Attempting to start the service manually (/etc/init.d/sut start) results in the process exiting immediately and returning to the stopped state.
  
  
• Syntax errors similar to the following are recorded in /var/run/log/sut.log:

  [INFO] :: [commandlineparser.cpp:119] :: Command SVC is invalid
  [INFO] :: [commandlineparser.cpp:130] :: at the end of the parseSingleCommand status is false
  [INFO] :: [hptoolsapplication.cpp:892] :: Command or parameter(s) is invalid or out-of-range. Use sut /help to get available commands and syntax.

Environment

VMware vSphere 8.0

Cause

This issue is caused by the behavior of the third-party SUT service module provided by HPE.

It occurs because the arguments (such as /svc) passed to the sut binary from the SUT service startup script are evaluated as an "invalid command" by the command-line parser in the current version. The process does not crash; instead, the SUT process gracefully exits upon detecting the argument error.

Resolution

Because this behavior is driven by a third-party (HPE) component, please contact Hewlett Packard Enterprise (HPE) Support for the resolution.
