Error: "Node type 'WITNESS' is not resizable" received when trying to scale VCF Operations CA cluster

Products

• VCF Operations

Issue/Introduction

• Attempting to scale up a VMware Cloud Foundation (VCF) Operations Continuous Availability (CA) cluster fails.

• The failure occurs when initiating a scale-up operation—either increasing the node size (CPU and memory) or adding additional storage to analytics nodes—from the following UI path: Build > Lifecycle > Components > Operations.

• Upon clicking Finish, the task fails and returns the following error message:

  Error: Node type 'WITNESS' is not resizable

Environment

VCF Operations 9.1

Cause

This occurs because the scale-up workflow inadvertently attempts to apply the scaling parameters to the cluster's witness node, which does not support resizing. This is a known issue in version 9.1 and is currently being fixed.

Resolution

As a workaround, please follow Scaling up a node in Aria Operations 8.x and later KB article.

This is a known issue and Broadcom Engineering is working to get this fixed in a future release.
