Environment

  • DX UIM 23.4.*
  • vmware probe 6.87 or higher

Cause

The error-> vmware] (12) login failed, VMWare API is unavailable, is usually caused by

  • Incorrect user credentials, and/or
  • Permission issues for the configured user

Resolution

To Resolve this issue: 

  • Check the vmware.cfg file or vmware probe via raw configure mode and make sure that the username and password are current, valid/what you expect.

  • To help troubleshooting wrong/no longer valid user name / password, from a web browser running on the robot where the vmware probe is deployed, try accessing the Managed Object Browser (MOB) of the configured vCenter or ESX server using the user and password configured in the failing probe profile:

https://<FQDN (or the IP address) for the ESX/ESXi or vCenter Server>/mob

If there are access issues for the configured user, they can be determined here.  Once these issues are resolved on the vCenter or ESX/ESXi server, test the connection again from the vmware probe.
