Hi all,  The SDC IP address is not the identifier that the ScaleIO cluster will use to communicate to SDCs. Instead it uses the GUID. The IP address is only loosely coupled to the SDC itself. When you change the IP address on the SDC host, it won't update the entry in the cluster itself. All it's looking at is the GUID, and then will talk to the IP address that is using that GUID.  If an SDC has 2 or more IP addresses, you will notice that it only shows one of them in the "query_all_sdc" output.  It is a cosmetic issue at this point and won't affect the connectivity after a reboot. The SDC will check it's configuration on boot, the MDM IPs and the GUID, then will connect using that info. It won't stop it from connecting on a reboot.
Hi  I have two hosts that are showing in the scaleio gui with the incorrect SDC IP address - they are showing as connected and are functioning fine. THese hosts were using the incorrect IP address in the past but i changed it and then installed scaleio on these but the gui is still showing the incorrect IP instead of the new one  I am concerned that if i boot these hosts then the sdc will go disconnected ?   # scli --query_all_sdc  shows the two hosts with state connected but the old ip address  , is this a problem ?
