Step 5 Upgrade the OS kernel.
l Example 1: RHEL 7.3
Upgrade the kernel of RHEL 7.3 to kernel-3.10.0-514.26.2.e17.x86_64 or later to
support orderly hot swap of NVMe drives.
a. Run the uname -r command to check the current kernel version.
Figure 3-40 Kernel version
b. Log in to the official Red Hat website to download the kernel upgrade package
(kernel-3.10.0-514.26.2.e17.x86_64.rpm for example).
c. Run the rpm -ivh kernel-3.10.0-514.26.2.e17.x86_64.rpm command to upload the
