Products

• VMware vSAN
• VMware SDDC Manager
• VMware Cloud Foundation

Issue/Introduction

When executing the prechecks for VCF installer, the ESA precheck fails with the following errors:

• vSAN partition already exist on ESX Host [HOSTNAME]
• No storage pool eligible disks found on ESX Host [HOSTNAME]

Below is a screenshot example of the errors in the prechecks:

Cause

This is due to an existing vSAN partition on the disk for the host. Before running through the VCF installer again, these need to be wiped accordingly.

Resolution

1. Log onto the host UI for the ESX host in question
   
   
2.  Navigate to Storage >  Disk with the partition table
   
   
3. Select Actions > Clear partition table

4. After the above action completes, go back to the VCF Installer and run the prechecks again.
