Linux Kernel upgrade on Endpoint with solidcore

Team, 

As we have seen some issues with the compatibility of solidcore on Linux machines with very latest Kernel upgrades done, got some queries as follows: 

1. There is an option to build a compatible kernel module if we wanted to install Solidcore on a Linux machine with incompatible Kernel, But what will happen if we upgrade the Kernel on a linux machine which already got McAfee solidcore installed on it? (Say upgrading to a Kernel version that is not compatible with solidcore). Will the solidcore stop working? Or it will impact the server functionality? 

2. If we wanted to upgrade the kernel version(incompatible one, very latest) on a linux machines with SOlidcore, what is the best practice? 

Thanks in advance.

Re: Linux Kernel upgrade on Endpoint with solidcore

Hi @Sabarikumar ,

Thank you for your post. You may request kernel support by filing a Product Enhancement Request (PER). For information about how to submit a PER, see KB60021.

I shall verify if Upgrading Kernel is supported when SolidCore is already installed.

Thanks

    Thanks for your reply Pravas! Raising a PER is something we can do for a new installation on incompatible kernel. Will wait for you to check the details about kernel upgrade on machine that already have solidcore installed.

    Hi @Sabarikumar 

    Thank you for posting in community forum. The workflow is, before upgrading the kernel where Solidcore is already installed you would need to review KB82066 to verify whether the target kernel is supported or not.

    -If the kernel is supported, you place the product in update mode and carry out the upgrade.

    -If the target kernel is not supported, then you need to create a custom build on a testbed and then manually deploy created build to production endpoints.

    You may reference the below FAQ’s which should give you more insights should you have any further queries.
