Not able to mount volume using multiple SDC networks
Hello all. I have 4 ESX hosts running SDC, 4 VMs running SDS (one per ESX host), and 3 VMs outside of the ESX cluster running all the MDM components. All are connected via two separate VLANs on separate interfaces. I have completed all the steps to get this setup, however, I am not able to mount the volume using BOTH networks (one works).
ESX1 10.209.46.192 10.209.47.192 /24
ESX2 10.209.46.193 10.209.47.193 /24
ESX3 10.209.46.194 10.209.47.194 /24
ESX4 10.209.46.195 10.209.47.195 /24
SDS1 10.209.46.1 10.209.47.1 /24
SDS2 10.209.46.2 10.209.47.2 /24
SDS3 10.209.46.3 10.209.47.3 /24
SDS4 10.209.46.4 10.209.47.4 /24
MDM1 10.209.46.150 10.209.47.150 /24 also has public IP for MDM cluster use
MDM1 10.209.46.151 10.209.47.151 /24 also has public IP for MDM cluster use
MDM1 10.209.46.152 10.209.47.152 /24 also has public IP for MDM cluster use
I setup the SDC using "scli --add_sdc --sdc_ip IP" and enabled --set_restricted_sdc_mode. I then mapped to the volume using the "allow_multi_map" option :
scli --map_volume_to_sdc --volume_name VOLUME01 --sdc_ip 10.209.46.192 --allow_multi_map
scli --map_volume_to_sdc --volume_name VOLUME01 --sdc_ip 10.209.47.192 --allow_multi_map
scli --map_volume_to_sdc --volume_name VOLUME01 --sdc_ip 10.209.46.193 --allow_multi_map
scli --map_volume_to_sdc --volume_name VOLUME01 --sdc_ip 10.209.47.193 --allow_multi_map
for all 8 IPs
# scli --query_all_sdc
MDM restricted SDC mode: Enabled
Query all SDC returned 8 SDC nodes.

Notice the bottom four are disconnected and have no GUID. Also notice it's not always ".47" that is not working! I went ahead and unmapped everything and started over:
# scli --query_all_sdc
MDM restricted SDC mode: Disabled
Query all SDC returned 4 SDC nodes.

(you cannot remove an SDC once it is connected, only when it goes away)

From an ESX host :

I checked the ESX host for local firewall rules - the SDC VIB created a rule to allow 7072, 9011, 6611 outbound. I would assume a firewall issue would affect both IPs though. Any ideas?
