Usage

When bootstrapping nodes the Bootstrap() function is used to establish the connection. It allows the user to specify an interface name, which is the local network interface that will be used to connect to the Rubrik node(s). If you are attempting a bootstrap from a system with multiple interfaces, you should set this parameter. If no interface is specified, the SDK will attempt to use the first non-loopback interface it finds. Below is the specification for the Bootstrap() function.

def Bootstrap(node_ip, interface=None, enable_logging=False)

Physical Cluster

Bootstrapping a physical cluster will only be possible using IPv6 (see mDNS below). Management and IPMI configurations are mandatory for a successful bootstrap.

Virtual Appliance

When bootstrapping a Virtual Appliance (Edge), this can be done either by using the IPv4 address as set on deployment or using IPv6 as stated below. IPMI addresses and DATA addresses can not be set and the encryption parameter should be set to "False".

Cloud cluster

Cloud Cluster instances have an IPv4 address dynamically assigned by the cloud provider, so there is no need to use mDNS for bootstrapping. Once the instances are deployed, gather the assigned IPs from the cloud provider console and use them in a similar manner to the example below. Cloud Clusters need to have the encryption parameter set to "False".

mDNS

By default, an un-bootstrapped Rubrik node will respond to multicast DNS (mDNS) queries directed to [node_serial_number].local. It is important that mDNS resolution is working properly on system where the SDK is called from if you wish to supply [node_serial_number].local to the Bootstrap() function as the node_ip value.

Any un-bootstrapped nodes on a network can be found using "avahi-browse -a" (Linux) or using a packet tracing utility filtering on mDNS (port 5353 - any OS).

mDNS resolution is not well supported on Windows, but it can be accomplished by installing the Apple Bonjour service, included with iTunes or Bonjour Print Services. mDNS is better supported on Linux and macOS, but you should verify working name resolution before using this function. If mDNS name resolution is not working on Linux, you can determine the link-local IPv6 address of the un-bootstrapped node(s) with the command avahi-resolve --name [node_serial_number].local or by using the python-zeroconf library. The link-local IPv6 address can then be passed to the Bootstrap() function instead of the mDNS name.

Troubleshooting

Enable logging by passing enable_logging=True to the bootstrap function. Example:

bootstrap = rubrik_cdm.Bootstrap(node_ip, enable_logging=True)

mDNS name resolution can be verified on systemd-based Linux systems using the command systemd-resolve --status. The resulting command should display MulticastDNS setting: resolve or MulticastDNS setting: yes. Additional information can be found at the links below.
