HP 3PAR StoreServ Cluster Extension Software Administrator Guide

IMPORTANT: User Account Control (UAC) is a feature in Windows Server 2008 onwards, that
can help prevent unauthorized changes to your computer. UAC prevents unauthorized changes
by requesting for permission or an administrator password before performing actions that can
affect your computer's operation or that change system settings that affect other users. For more
information on UAC, see http://windows.microsoft.com/en-US/windows-vista/
What-is-User-Account-Control .
If you log in to the cluster node as a domain user with domain administrator privileges, you cannot
run the CLX applications such as HP 3PAR StoreServ Cluster Extension Configuration Tool
[CLX3PARCONFIG.exe], clx3parrun.exe or Clx3PARResConfig.exe. This is because the
UAC is enabled by default. You must elevate the logged on user privileges to the local administrator
and execute the applications. This can be done by using the Run as administrator option.

If TPDNOCERTPROMPT environment variable is set, then remove the TPDNOCERTPROMPT
