I successfully deployed scaleio 1.32 for Vsphere 5.5 followed instruction ScaleIO Quick Start Guide for VMware . All looks Ok. Just few questions at this stage:

1) What means  "ScaleIO Installer" when I connect to gateway via web browser? It propose me to upload and install some packages. What packages?  Does gateway has some additional functionality via web and I have to configure it? Or it just tools for manual scaleio installation and future updates?

2) My scaleio successfully pass switching of of each server, but when I switched of the first MDM server, the second MDM become first and still first after original first back alive. So, I had have to reconnect GUI to the second IP. Is it Ok? Is it possible to have GUI automatically reconnect to current first MDM?  Is it possible to have one main IP address for GUI, not related to status of current first MDM?

3) I didn't find in GUI where I can change scaleio configuration. Not create additional pools and volumes etc, but, for example, change "Call Home" mail server or syslog server parameters. Is it possible?

Thanks
