Slave MDMs disconnected

New host are disconnected in vmware infrastructure. All MDM and Management IPs with full access between hosts.

Host with role: SDS / SDC / MDM

My plan:

Replace old slave MDMs with error: add new standby and replace old slave to new slave MDMs

> Problem:

# scli --add_standby_mdm --new_mdm_ip 10.10.110.27 --mdm_role manager --new_mdm_management_ip 10.10.99.141 --new_mdm_virtual_ip_interface eth1

Error: MDM failed command.  Status: Communication error

> Solutions:

# rpm -i EMC-ScaleIO-mdm-2.0-11000.174.sles11.3.x86_64.rpm

Successfully finished repository formatting operation

Create Service ===> added the mdm-2.0.11000.174 process to /etc/inittab

> add "actor_role_is_manager=1" and restart MDMs:

# /opt/emc/scaleio/mdm/bin/delete_service.sh

# /opt/emc/scaleio/mdm/bin/create_service.sh

> and last steps:

# scli --add_standby_mdm --new_mdm_ip 10.10.110.27 --mdm_role manager --new_mdm_management_ip 10.10.99.141 --new_mdm_virtual_ip_interface eth1

Successfully added a standby MDM. Object ID

> replace slave MDM:

# scli --remove_standby_mdm --remove_mdm_ip 10.10.110.22

Successfully removed the standby MDM.

> In final host working are fine:
