Adding new nodes
While adding a new node to the cluster, users can modify the following:
The operating system
CUDA
OFED
A new node can be added using the following ways:
When the discovery mechanism is
switch-based
:Edit or append JSON list stored in
switch-based-details
ininput/provision_config.yml
.
Note
All ports residing on the same switch should be listed in the same JSON list element.
Ports configured via Omnia should be not be removed from
switch-based-details
ininput/provision_config.yml
.
Run
provision.yml
.
When the discovery mechanism is
mapping
:Update the existing mapping file by appending the new entry (without the disrupting the older entries) or provide a new mapping file by pointing
pxe_mapping_file_path
inprovision_config.yml
to the new location.Run
provision.yml
.
When the discovery mechanism is
snmpwalk
:Run
provision.yml
once the switch has discovered the potential new node.
When the discovery mechanism is
bmc
:Run
provision.yml
once the node has joined the cluster using an IP that exists within the provided range.
Alternatively, if a new mode is to be added with no change in configuration, run the following commands:
cd provision
ansible-playbook discovery_provision.yml
