Configuring the gateway node for on-premises InfoScale cluster

Complete the following steps -

  1. Download the latest gateway node installer or RPM from the 'download' icon located at the upper right corner of the Application Mobility portal.

    Note:

    VIOM customers can upgrade their management server to minimum 8.0.0.500 version to get the gateway installed on your management server. In that case, you can skip to the step to register the node with the mobility portal.

  2. Log on to the gateway node and copy the downloaded VRTSgateway RPM file to the gateway node.
  3. Run the following command from the directory where you copied the .rpm file to install the YAML for setting up the gateway node.

    yum localinstall <VRTSgateway rpm file>

    If the gateway node is configured on RHEL 7.9, run the following commands rpm -ivh <VRTSgateway rpm path> --nodeps

    cd /opt/VRTSgateway/bin

    ./setup_gateway.sh

    Note:

    To update an existing gateway after downloading the new version, use the command yum upgrade <package name>.

  4. Run /opt/VRTSgateway/bin/gateway -register to register the node.
  5. Enter the Arctera Application Mobility credentials and name of the datacenter when prompted. You can enter any name here.
  6. Run systemctl start gatewayd to start the gateway node.
  7. Run systemctl enable gatewayd to ensure that the service starts in case of a gateway node reboot.
  8. Create/Edit /etc/ansible/hosts and add the InfoScale cluster names and user credentials as under:

    [Name of the InfoScale cluster]

    <Name of the first node > ansible_ssh_user=root ansible_ssh_pass=<password>

    <Name of the second node> ansible_ssh_user=sudo_user ansible_ssh_pass=<password>

    For example,

    # cat /etc/ansible/hosts

    [cluster-1]

    dl360g10-074-vip01 ansible_ssh_user=root

    dl360g10-074-vip02 ansible_ssh_user=root

    [cluster-2]

    dl360g10-074-vip03 ansible_ssh_user=sudo_user

    dl360g10-074-vip04 ansible_ssh_user=sudo_user

    r750xs-32-vm1 ansible_ssh_user=sudo_user ansible_ssh_pass=root123 ansible_sudo_pass=root123

    Note:

    Arctera recommends setting up passwordless SSH. For this, you must enter information about all the InfoScale clusters you want to migrate. Ensure that you assign sudo permissions to the cluster node users for passwordless SSH communication from the gateway node. Do not enter ansible_ssh_pass in /etc/ansible/hosts file if passwordless SSH is configured between the gateway node and the InfoScale Cluster.

  9. If you do not want to set up passwordless SSH, install sshpass RPM on the gateway nodes to connect to the Arctera InfoScale clusters. The credentials required for the same are to be provided in the /etc/ansible/hosts file in the format mentioned in the step above.

The gateway node is now connected to the InfoScale cluster, and the logs are saved at /var/log/vrtsgateway.log.
