- On HPE Ezmeral Runtime Enterprise 5.6.0 and later
releases:
- RHEL 8.x is supported on Kubernetes cluster hosts, with all hosts in the Kubernetes cluster on RHEL 8.x.
- For fresh installations of HPE Ezmeral Runtime Enterprise, RHEL 8.x is also supported on HPE Ezmeral Runtime Enterprise control plane (Controller, Shadow, Arbiter, and Gateway) hosts.
- For existing deployments of HPE Ezmeral Runtime Enterprise, upgrading control plane (Controller, Shadow, Arbiter, and Gateway) hosts to RHEL 8.x is not supported.
See also Operating System Requirements.
- On HPE Ezmeral Runtime Enterprise 5.5.x and earlier releases, RHEL 8.x is supported on Kubernetes hosts only, with all hosts in the Kubernetes cluster on RHEL 8.x. See Operating System Requirements.
** The minimum kernel version requirement is relevant to deployments that have been upgraded from versions of HPE Ezmeral Runtime Enterprise prior to 5.5.0 only.
For information about operating system configuration requirements for all OS versions, see Operating System Requirements and Configuration Requirements.
Host operating system upgrades to minor operating system releases are supported. For example, if HPE Ezmeral Runtime Enterprise is installed on RHEL 7.8, you can upgrade the host operating system to RHEL 7.9. For more information about upgrading host operating systems, see System Maintenance.
To minimize the need for troubleshooting, Hewlett Packard Enterprise recommends newer kernel versions.
SELinux is supported on HPE Ezmeral Runtime Enterprise 5.2 and later in Enforcing, Permissive, and Disabled mode as follows:
- To enable Enforcing mode on nodes that are part of HPE Ezmeral Data Fabric on Kubernetes, contact Hewlett Packard Enterprise Support.
- The mode cannot be changed after installing HPE Ezmeral Runtime Enterprise.
- For SLES 15 SP2 and SLES 15 SP3, supported with HPE-installed SELinux policies only.
