Create the 5-node MDM cluster

Create the 5-node cluster.

1. Create the MDM single-node cluster on MDM 1, by running the following command on MDM 1:

   scli --create_mdm_cluster --master_mdm_ip <IP of MDM 1> --master_mdm_management_ip <Management IP of MDM 1> --master_mdm_name <Name to give MDM 1> [--cluster_virtual_ip <IP>]  [--master_mdm_virtual_ip_interface <INTF>] --accept_license

   Example:

   scli --create_mdm_cluster --master_mdm_ip 192.168.1.152 --master_mdm_management_ip 10.103.110.152 --master_mdm_name mdm152 --cluster_virtual_ip 192.168.111.152 --master_mdm_virtual_ip_interface eth4 --accept_license

   NOTE: Each MDM name must be unique. Ensure that each server on which MDM is installed has a unique hostname.
2. Log in and change the MDM password, by running the following commands on MDM 1:

   scli --login --username admin --password admin

   scli --set_password --old_password admin --new_password Scaleio123

   The login password is changed from admin to Scaleio123.

3. Log in with the new credentials:

   scli --login --username admin --password Scaleio123

4. Add the secondary MDMs (MDM 2 and MDM 3) to the MDM cluster as Standby MDMs, by running the following commands on MDM 1:

   scli --add_standby_mdm --new_mdm_ip <IP of MDM X> --mdm_role manager --new_mdm_management_ip <Management IP of MDM X> --new_mdm_virtual_ip_interface <INTF> --new_mdm_name <Name to give MDM X>

   Examples:

   scli --add_standby_mdm --new_mdm_ip 192.168.1.153 --mdm_role manager --new_mdm_management_ip 10.103.110.153 --new_mdm_virtual_ip_interface eth4 --new_mdm_name mdm153

   scli --add_standby_mdm --new_mdm_ip 192.168.1.154 --mdm_role manager --new_mdm_management_ip 10.103.110.154 --new_mdm_name mdm154

5. Add TB 1 and TB 2 to the MDM cluster as tiebreakers, by running the following commands on MDM 1:

   scli --add_standby_mdm --new_mdm_ip <IP of TB X> --mdm_role tb --new_mdm_name <Name to give TB X>

   Examples:

   scli --add_standby_mdm --new_mdm_ip 192.168.1.155 --mdm_role tb --new_mdm_name tb155

   scli --add_standby_mdm --new_mdm_ip 192.168.1.156 --mdm_role tb --new_mdm_name tb156

6. (Optional) Query the cluster to verify that it is running in single mode, by running the following command on MDM 1:

   scli --query_cluster

   Output, similar to the following, is displayed:

   Cluster: Mode: 1_node

7. Switch to 5-node cluster mode, by running the following command on MDM 1:

   scli --switch_cluster_mode --cluster_mode 5_node --add_slave_mdm_name <MDM 2 name>,<MDM 3 name> --add_tb_name <TB 1 name>,<TB 2 name>

   Example:

   scli --switch_cluster_mode --cluster_mode 5_node --add_slave_mdm_name mdm153,mdm154 --add_tb_name tb155,tb156

8. (Optional) Query the cluster to verify that it is running in cluster mode, by running the following command on MDM 1:

   scli --query_cluster

   Output, similar to the following, is displayed:

   # scli --query_cluster
