c. Run the rpm -ivh kernel-default-4.4.74-92.32.1.x86_64.rpm command to upload
the upgrade package to the OS for installation.
Figure 3-43 Installing the upgrade package
d. Restart the OS after the installation is complete.
e. Run the uname -r command to check the kernel version.
If it is still the original kernel version, change the version in the grub.cfg file.
Step 6 Perform an orderly hot swap of an NVMe drive.
1. Obtain the slot number, B/D/F, and slot ID of the NVMe drive in the OS.
Generally, the slot number is the same as that marked on the compute node panel. If they
are inconsistent:
– Run find /sys -name nvme0n1 to query the bus number of the SSD device.
– Run lspci -vvv -xxx -s <B/D/F> |grep -i slot to query the slot No.

The Device (B/D/F) values vary depending on the setting of the VMD function. The
values in this table are based on the assumption that the VMD function is disabled.
2. Change the value of the a8 register. Otherwise, NVMe drives do not support orderly hot
swap.
