Communication error adding Slave MDM
Fresh install with EMC ScaleIO v2.0-6035.0 using the vcenter plugin on VMware ESXi, 6.0.0, 3380124
During the deployment process, I get this error adding the slave MDM
FAILED (Error code: COMMUNICATION_ERROR) : Add Slave MDM
I already moved to a different set of esx servers (different hardware vendor) and got the exact same error.
I can ping between the hosts using the data IPs below.
Any ideas?

A few things to do on the ESXi hosts to verify connectivity:
1. Make sure the SDC is installed. It should be
esxcli software vib list |grep sdc
2. Check the SDC parameters
cat /etc/vmware/esx.conf |grep scini
You should see a GUID and the MDM IPs (or Virtual IPs if you are using them) listed there. If you don't see the any of those listed, go to step 3.
3. Add the SDC parameters as follows:
esxcli system module parameters set -m scini -p "IoctlIniGuidStr=GUID_GOES_HERE ioctlMdmIPStr=10.0.0.x,10.0.0.y,10.1.1.x,10.1.1.y"
(The above is all one line). Substitute your own unique GUID and your own IPs for the MDMs.
4. Reboot the ESXi host for the parameter changes to take effect properly.
