vmservices vsphere credential check
vmservices vsphere credential modify [-server server] [-username user] [-password passwd]
The vmservices vsphere credential check command attempts to verify the current vSphere authentication info with the vSphere host, indicating either success or a reason for failure.
Finally, the vmservices vsphere credential modify command is used to set the vSphere credentials: server, username, and password. The server identifies the vSphere server (either a vCenter server or an ESX host) controlling this virtual machine. It can be either an IP address or (if name resolution enabled) a hostname. The username identifies a vSphere user (only ``read-only'' permissions required), and password is their password. If username is specified without password we will prompt for password without echoing. The password prompt is unavailable when using rsh.
