Disconnected SDC

Hello ScaleIO Community,

I have noticed that all the SDC are disconnected from my Scaleio cluster, below an extract of the scli output:

#scli --query_all_sdc
MDM restricted SDC mode: Disabled
Query all SDC returned 11 SDC nodes.
SDC ID: d463268300000000 Name: N/A IP: 10.32.130.42 State: Disconnected GUID: 74DEDEE4-C838-4278-8347-C67EDC0F9F07 OS Type: LINUX Loaded Version: N/A Installed Version: 2.0.12000 Restart required
    Read bandwidth:  0 IOPS 0 Bytes per-second
    Write bandwidth:  0 IOPS 0 Bytes per-second

The scini service is running as expected, see below.

# systemctl status scini

Restarting the scini service didn't help, how can I reconnect all the SDC? What would be your suggested step to troubleshooting this issue?
