l If yes, go to Step 9.
l If no, go to Step 7.
Step 7 Check whether the following message is displayed. The message indicates that the new
NVMe driver fails to be installed during the installation.
Warning: fail to install the new nvme kernel module. Please install the new nvme
kernel module manually or reboot the system.
l If yes, go to Step 8.
l If no, go to Step 12.
Step 8 Check whether restarting the OS will affect services.
l If yes, restart the OS when no service is running and go to Step 12.
l If no, restart the OS and go to Step 12.
Step 9 Check whether restarting the OS will affect services.
l If yes, go to Step 10.
l If no, restart the OS and go to Step 12.
Step 10 Run the modprobe -r nvme command to uninstall the original driver. During the
uninstallation, check whether a message is displayed indicating that the driver is in use. If yes,
the uninstallation fails.
l If yes, restart the OS when no service is running and go to Step 12.
l If no, go to Step 11.
Step 11 Run the modprobe nvme command to install the new driver. Check whether a warning or
error is displayed during the installation.
l If yes, restart the OS and go to Step 12.
l If no, go to Step 12.
Step 12 Run the modinfo nvme command to check the driver author information to determine
whether the driver is successfully installed.
If the author in the command output is as follows, the driver is successfully installed.

l If yes, go to Step 13.
l If no, go to Step 15.
Step 13 If a PCIe SSD device has been installed on the server, check whether the driver has initialized
the device.
Check whether the NVMe device exists in the /dev directory to determine whether the device
initialization is complete.
l If yes, go to Step 14.
l If no, go to Step 15.
Step 14 if the OS uses the irqbalance service to balance CPU interrupts, restart the service by using
one of the following commands after re-loading the driver module:
l For RHEL 6 or CentOs 6, run service irqbalance restart.
l For SLES 11 or UVP, run service irq_balancer restart.
l For SLES 12 or RHEL 7, run systemctl restart irqbalance.service.
