After change vcenter hostname and ip when i try to access a TSM Vmware Gui Web interface:
On the machine where the “Tivoli Data Protection for VMware” package is installed, open the Windows Services applet and stop the service:
Open the file vmcliConfiguration with notepad (find the file in my case on c:IBMtsmtdpvmwarewebserverusrserversveProfiletsmVmGUI) and change the name of old vcenter with the new vcenter
<vcenter_url>https://xxxx.xxx.xx/sdk</vcenter_url>
Now restart the service “Data Protection for Vmware web Server service” and retry to connect at web interface
