Product(s): Resiliency Platform (10.3)

Configuring the Replication Gateways

After the virtual appliance deployment, when you log into the virtual appliance console for the first time using the admin user credentials, the bootstrap process is automatically invoked. This bootstrap process is used to set up or configure the Resiliency Platform component for the first time.

The default network protocol for virtual appliance is Dynamic Host Configuration Protocol (DHCP). If the appliance detects DHCP during the first boot or before the completion of bootstrap process, the appliance network automatically gets configured. After the network configuration, you can either use the virtual appliance console or Secure Shell (SSH) to log in as admin user and complete the bootstrap process.

If DHCP is not configured in your environment, you have an option to use a static IP for the appliance. Since the appliance network is not automatically configured in this case, you can only use the console to log into the virtual appliance.

To configure a Replication Gateway

Prerequisites:
- See Prerequisites for configuring Resiliency Platform components.
- The Replication Gateway configuration requires an extra disk of at least 50 GB, to be used as a staging disk. You can attach this disk before configuration or during the configuration. The default disk size of 50GB lets you protect up to 8 virtual machines and each additional virtual machine requires a disk of 6GB size. You can increase the size of the disk by using lvm option of the klish commands:
- In any non-AWS environment, log in to the virtual appliance console or SSH using the following credentials:
  - Username: admin
  - Password: P@ssw0rd
  Note:
  In Azure environment, the password would be the one provided during deployment.
  After a successful login, you are prompted to change the password of the admin user.
  See Password policies for Resiliency Platform virtual appliance.
  If you are logged in to SSH, you will be logged off the SSH session after the password change and you need to again log in to complete the rest of the steps of the bootstrap process. If you are logged in to the virtual appliance console, you can continue and complete the rest of the steps of the bootstrap process.
- In AWS environment, do one of the following:
  - From a Linux client system:
    Use SSH with the private key from the key-pair that you had selected while launching the instance in AWS. For example:
    ssh -i private_key_file admin@ip_address_of_aws_instance
    Ensure to modify the permissions for the private key file as 600 before using the file.
  - From a Windows client system:
    Follow the documentation of AWS to connect to the Linux instance from a Windows system using PuTTY.
Accept the End User License agreement (EULA) to proceed with the configuration.
In the Host Network Settings section, you can configure the appliance network by using DHCP or static IP.
See Configuring network settings for Replication Gateway.
In the Appliance Settings section, do the following:
- Press the Enter key to confirm the use of an NTP server for configuring the date and time.
- You are required to select the time zone. Follow the instructions as displayed on the virtual appliance console or SSH session to select the correct time zone.
- Enter the FQDN or IP address of the NTP server. The appliance verifies the NTP server details. If there are any issues, details are displayed on the screen and you are prompted to enter the details again.
You can reset the timezone and NTP server at a later point of time using klish menu. Changing the system settings can affect the product functionality if incorrect values are set.
In the Product Settings section, the virtual appliance is configured as Replication Gateway.
You are prompted to confirm if you want to enable FIPS for the Replication Gateway appliance.
See About FIPS enablement for Replication Gateway appliance .
Note:
If you confirm to enable FIPS for the appliance, the appliance will be restarted after finishing the bootstrap process.
You are prompted to attach an extra disk to the appliance. If you have already attached the extra disk, press Enter to confirm. If you have attached more than one extra disk, all disks are listed and you need to select the extra disk that you want to use. If you have not already attached the extra disk, attach the extra disk and then confirm or select the extra disk to be used. Ensure that you attach a thick provisioned disk.
While attaching the extra disk to the Replication Gateway appliance in AWS, use the full device path and use the format xvdb[a-z] instead of sd[a-z]. For example use /dev/xvdba instead of just xvdba.
After a successful product configuration, a confirmation message will be displayed and you will be logged out of the virtual appliance console.
If the bootstrap is in AWS environment, you must log in once again using the SSH key and set the admin user password. You need to use this password for adding the gateway to the resiliency manager.
Add the Replication Gateway to an IMS using the Resiliency Manager console.
See Adding a Replication Gateway.
