Issue/Introduction

Safe way to remove old baselines from ESXi and also from vCenter level.

Environment

Resolution

After patching your ESXi using Manually created (Custom) baselines, it is safe to detach the Baseline & delete it from the Update manager/Life Cycle Manager, if you no longer need them.

Detailed steps for Baseline removal

Detach Baseline from ESXi:

 

• In the vSphere Client, navigate to the vSphere Lifecycle Manager compliance view for an individual host or a container object.

1. Navigate to a host, cluster, or a container object.
2. Click the Updates tab.
3. Select Hosts > Baselines.

• In the Attached Baselines pane, select one or more baselines or baseline groups and click Detach.
• The Detach dialog box opens.
• Select the object to detach the baseline or baseline group from and click Detach.
• The baseline is removed from the Attached Baselines list.

 

 

Delete Custom Baselines from Vcenter:

• Required privileges: VMware vSphere Lifecycle Manager > Manage Baselines
• Navigate to the vSphere Lifecycle Manager home view.
• In the vSphere Client, select Menu > Lifecycle Manager.
• Select a vCenter Server system from the Lifecycle Manager drop-down menu.
• The drop-down menu is available only when multiple vCenter Server systems are connected by a common vCenter Single Sign-On domain.
• By selecting a vCenter Server system, you specify which vSphere Lifecycle Manager instance you want to administer.
• On the Baselines tab, select a baseline or a baseline group from the list and click Delete.
• The Delete Baseline dialog box opens.
• Click Yes to confirm the deletion of the selected baseline or baseline group.

 

Important Note:

This process is applicable only for Custom Baselines. Do not remove Default Baselines in built from the update manager/Life cycle manager.
