Running the cim-diagnostic.sh or swfw.sh command fails with the error: enumInstances Failed initialization

Products

• VMware vSphere ESXi

Issue/Introduction

Symptoms:

• CIM subsystem does not work reliably.
• Running the cim-diagnostic.sh command fails.
• Running the swfw.sh command fails.
• When querying the hardware status manually using the cim-diagnostic.sh command or creating a support bundle with the vm-support command, you see messages similar to:
  
  CIM Diagnostic dump for root/interop
  Dumping instances of CIM_Namespace
  error: enumInstances Failed initialization
  Dumping instances of CIM_RegisteredProfile
  error: enumInstances Failed initialization
  CIM Diagnostic dump for root/cimv2
  Dumping instances of CIM_Sensor

Environment

VMware vSphere ESXi 5.5
VMware vSphere ESXi 5.0
VMware vSphere ESXi 5.1

Cause

This issue occurs when IPv6 is disabled on the host, but there is an IPv6 localhost entry in the /etc/hosts file. The cim-diagnostic.sh and swfw.sh scripts invoke the enum_instances command which by default tries to connect to the localhost over IPv6 when the hosts file contains an IPv6 localhost address. Because IPv6 is disabled, the connection and the calling script fails.

Resolution

This is a known issue in VMware ESXi.

To work around this issue, either re-enable IPv6 (requires reboot) or comment out the IPv6 localhost entry in the /etc/hosts file (no reboot required).

To comment the IPv6 localhost entry:

1. Log in to the host using SSH. For more information, see Using ESXi Shell in ESXi 5.x (2004746).
2. Edit the hosts file located at /etc/ using a text editor. For more information, see Editing configuration files in VMware ESXi and ESX (1017022).
   
   Example output:
   
   # Do not remove the following line, or various programs
   # that require network functionality will fail.
   127.0.0.1 localhost.localdomain localhost
   ::1 localhost.localdomain localhost
   
   
3. Comment out IPv6 line that begins with ::1:
   
   # Do not remove the following line, or various programs
   # that require network functionality will fail.
   127.0.0.1 localhost.localdomain localhost
   #::1 localhost.localdomain localhost
   
   Note: If the ESXi host is rebooted this workaround will need to be reapplied
