Issue/Introduction

During Apply Changes, the hubsm-install errand fails with the error:

           2026-04-27 18:18:07 [INFO] Install/update Tanzu Hub ...

The error indicates that the internal cluster doesn't have minimum capacity requirements, hence the errand stopped abruptly.

Environment

Tanzu Hub

Cause

This appears to be due to the "High Availability" mode being enabled but the instance counts were left at default ("Automatic") settings and not increased according to the documented HA compute requirements.

Resolution

Review the HA compute requirements documentation, and increase the instances counts accordingly.
