Best Practices
Ensure that PowerCap policy is disabled and the BIOS system profile is set to ‘Performance’ on the Control Plane.
Always execute playbooks within the directory they reside in. That is, always change directories (
cd
) to the path where the playbook resides before running the playbook.Ensure that there is at least 50% (~50GB) free space on the Control Plane root partition before running Omnia. To maintain the free space required, place any ISO files used in the
/home
directory.Use a PXE mapping file even when using DHCP configuration to ensure that IP assignments remain persistent across Control Plane reboots.
Avoid rebooting the Control Plane as much as possible to ensure that all network configuration does not get disturbed.
Review the prerequisites before running Omnia Scripts.
Ensure that the firefox version being used on the control plane is the latest available. This can be achieved using
dnf update firefox -y
It is recommended to configure devices using Omnia playbooks for better interoperability and ease of access.
Ensure that the
/var
partition has adequate space to complete commands and store images.Run
yum update --security
routinely on the control plane for the latest security updates.
