## Can Cobbler deploy both Rocky and CentOS at the same time?
No. During Cobbler based deployment, only one OS is supported at a time. If the user would like to deploy both, please deploy one first, **unmount `/mnt/iso`** and then re-run cobbler for the second OS.

## Why do Firmware Updates fail for some components with Omnia 1.1.1?
Due to the latest `catalog.xml` file, Firmware updates fail for some components on server models R640 and R740. Omnia execution doesn't get interrupted but an error gets logged. For now, please download those individual updates manually.

* To change the Kubernetes version from 1.16 to 1.19 or 1.19 to 1.16, you must redeploy the entire cluster.
* The Kubernetes pods will not be able to access the Internet or start when firewalld is enabled on the node. This is a limitation in Kubernetes. So, the firewalld daemon will be disabled on all the nodes as part of omnia.yml execution.
* Only one storage instance (Powervault) is currently supported in the HPC cluster.
* With the latest `catalog.xml` file, firmware updates of a few components might fail for server models: R640 and R740. Note that Omnia doesn't halt or get interrupted despite these failures. (Fix Expected by 17th December 2021)
