Provision

⦾ Why am I unable to do ssh to the booted nodes via omnia_core container?

Potential Causes: This issue is due to SSH host key mismatch.

Resolution: User needs to manually run the below command inside omnia_core container:

ssh-keygen -R  <node_admin_ip>

This removes all SSH entries for that IP from your local ~/.ssh/known_hosts file.

⦾ Why are the hostname and root password not configured on the nodes after boot?

Potential Causes: Cloud-init is not properly loaded on the target servers during provisioning. For more information, see Inconsistent cloud-init behavior with multiple node group configurations.

Resolution: Wait for 5 minutes and retry provisioning the node. If the issue persists, redeploy the cluster after running the oim_cleanup.yml playbook.

⦾ Why do systems with BCM57504 card fail to PXE boot with firmware 23.x.x and above?

Potential Causes: iPXE version used in Omnia 2.1 does not support firmware version 23.x.x and above for Broadcom BCM57504 card.

Resolution: Downgrade the BCM57504 card firmware to Network_Firmware_P5P4D_LN64_22.92.07.50_02 and perform an A/C powercycle on the system.
