Command failed: Could not set connection security policy between MDM to SDS on , due to: Failed loading

Hi, I was installing VxFlex OS as a 3-node cluster on mix environment. Windows 2012R2 as master and Ubuntu 14.04 slave and TB via Installation manager. As I am using IM server also as a component MDM component(W2k12r2). During configure phase two phases are failed and 11 aborted. Failed phases showing following errors: --------------------------------------- Command failed: Could not set connection security policy between MDM to SDS on 172.30.76.62,172.30.76.67 due to: Failed loading the security module --------------------------------------- ---------------------------------------- Command failed: Could not set spare capacity for all storage pools on [172.30.76.62, 172.30.76.67] due to: Some SDS were not added to the system and hence recalculation is needed. Aborted setting spare capacity for rest of storage pools. ---------------------------------------- Can anyone help to resolve these issue and configure my VxFlex setup?
