# This playbook is intended to bootstrap network configuration of the iDRACs on
|
|
# a set of Dell servers. By default, iDRACs have a known static IP address
|
|
# configured. Since all iDRACs have the same default IP address, we need a way
|
|
# to isolate a single iDRAC while we set its network configuration. We do this
|
|
# using a temporary VLAN accessible from one of the controllers.
|
|
#
|
|
# We use the following procedure:
|
|
# 1. Create a VLAN interface on the controller node with IP in the iDRAC
|
|
# default subnet.
|
|
# 2. Create the temporary bootstrap VLAN on the switch, accessible by the
|
|
# controller and trunked to all switches within the network.
|
|
# 3. For each iDRAC switch port in turn, flip to the temporary VLAN and
|
|
# configure the iDRAC's IP address, before returning the port to the iDRAC
|
|
# management VLAN.
|
|
# 4. Remove the temporary bootstrap VLAN from the switch.
|
|
# 5. Remove the VLAN interface on the controller node.

|
|
# idrac_network_ips. If omitted all idracs will be bootstrapped.
