Add second network to existing ScaleIO installation

I have ScaleIO installation with one network card enabled for data (one management network, one data network).

I want to add second data network.

I configured second network in all SDSs, test all of them by ping. everything ok.

Then I add these IPs by --add_sds_ip commands:

Protection Domain 0a20b3bd00000000 Name: default

SDS ID: b30de1820000000b Name: ds1-ESX State: Connected, Joined IP: 10.3.1.127,10.3.2.127 Port: 7072

SDS ID: b30d936000000001 Name: d2-ESX State: Connected, Joined IP: 10.3.1.124,10.3.2.124 Port: 7072

SDS ID: b30dba6f00000000 Name: d3-ESX State: Connected, Joined IP: 10.3.1.129,10.3.2.129 Port: 7072

SDS ID: b30d6c4f00000004 Name: ds4 State: Connected, Joined IP: 10.3.1.128,10.3.2.128 Port: 7072

SDS ID: b30de1830000000c Name: ds5 State: Connected, Joined IP: 10.3.1.125,10.3.2.125 Port: 7072

SDS ID: b30d453f00000002 Name: ds6 State: Connected, Joined IP: 10.3.1.123,10.3.2.123 Port: 7072

SDS ID: b30d936200000007 Name: ds7 State: Connected, Joined IP: 10.3.1.121,10.3.2.121 Port: 7072

But new network is not used by ScaleIO:

scli --query_sds_connectivity_status --protection_domain_name default:

ID: b30de1830000000c <===> ID: b30dba6f00000000  Connected Count 1

  10.3.1.129     : Connected

  10.3.2.129     : Not Connected

ID: b30de1830000000c <===> ID: b30d936000000001  Connected Count 1

  10.3.1.124     : Connected

  10.3.2.124     : Not Connected

ID: b30de1830000000c <===> ID: b30d453f00000002  Connected Count 1

  10.3.1.123     : Connected

  10.3.2.123     : Not Connected

....

All second networks are in "Not Connected" states (10.3.2.0/24).

PS. When I choose 2 data networks during ScaleIO installation - all cards are used. But I need to add second card without reinstall of all datastore.
