To install the ONTAP Mediator service, you must ensure all prerequisites are met, fetch the installation package and run the installer on the host. This procedure is used for an installation or an upgrade of an existing installation.

About this task

Any library packages except the kernel can safely be updated but might require a reboot to take affect within the ONTAP Mediator application. A service window is recommended when a reboot is required.

If you install the yum-utils package, you can use the needs-restarting command.

The kernel core can be updated if it is being updated to a version that is still supported by the ONTAP Mediator version matrix. A reboot will be mandatory, so a service window is required.

The SCST kernel module must be uninstalled prior to the reboot, then re-installed after the reboot.

Upgrading to a kernel beyond the supported OS release for the specific ONTAP Mediator release is not support. (This likely indicates that the tested SCST module won’t compile).
