Hi Alex,  Try to check your gatewayUser.properties file to see if it's poiting to the correct MDM IP addresses. Also see what's in the operations.log and scaleio.log, maybe there is some clue?  Best, Pawel
Greetings,  Environment:  ScaleIO 2.0-6035.0  The environment is fully deployed. I can authenticate against MDM using traditional "admin" and password, no problem:  ScaleIO-192-168-120-151:~/install # scli --login --mdm_ip 192.168.120.150 --username admin --password XXXXXXXXX Logged in. User role is SuperUser. System ID is 076534e45e5ed7ca  ScaleIO-10-60-120-151:~/install # scli --mdm_ip 192.168.120.150  --sdc --query_all_sdc MDM restricted SDC mode: Disabled Query all SDC returned 15 SDC nodes. SDC ID: d503826c0000000e Name: N/A IP: 192.168.120.165 State: Disconnected GUID: 99222D6D-0BED-4DAA-994E-D76D7CD25F08 Version: N/A     Read bandwidth:  0 IOPS 0 Bytes per-second     Write bandwidth:  0 IOPS 0 Bytes per-second SDC ID: d503826b0000000d Name: N/A IP: 192.168.120.163 State: Disconnected GUID: 28A19C7E-636A-4020-A674-5796BC341D8B Version: N/A     Read bandwidth:  0 IOPS 0 Bytes per-second     Write bandwidth:  0 IOPS 0 Bytes per-second SDC ID: d503826a0000000c Name: N/A IP: 192.168.120.161 State: Disconnected GUID: FC3602E2-B3A2-4D5B-B6AA-721E1603C51D Version: N/A     Read bandwidth:  0 IOPS 0 Bytes per-second     Write bandwidth:  0 IOPS 0 Bytes per-second ...  My REX-Ray was working fine as well, authenticating against my ScaleIO Gateway, but now, it is failing to authenticate.  [root[NAME] rexray]# curl -k --user admin:XXXXXX [URL] {    "message" : "Unauthorized",   "httpStatusCode" : 401,   "errorCode" : 0 }[root[NAME] rexray]#   Any clues on how to tackle the problem?? Why would it stop authenticating ?  Thanks,  Alex
Cannot Authenticate Against ScaleIO Gateway Any Longer
