Issues enabling VCHA on vCenter Server when swap file is set to a separate directory.

Products

• VMware vCenter Server
• VMware vCenter Server 7.0
• VMware vCenter Server 8.0

Issue/Introduction

Symptoms:
If you enable the VCHA, it will state that the vCenter cannot exist in multiple directories.

Environment

VMware vCenter Server 8.0.x
VMware vCenter Server 7.0.x

Cause

The reason for this is that it is handling the user world swap location but not fully notating which file is being affected.

Resolution

This is working as designed.

Workaround:

Refer to the two options below to resolve this issue:

1. Disable VMX Swap for the Active VC VM:
 - set the following configuration parameter:
   sched.swap.vmxSwapEnabled = FALSE
 - This will disable the VMX userworld swap file for the active VC VM.

2. Set VMX swap for the Active VC VM to be the VM directory
 - set the following configuration parameters:
   sched.swap.vmxSwapEnabled = TRUE
   sched.swap.vmxSwapDir = <VM Directory> ---> Full path of directory when VM's vmx file is located on the host
