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
.
l
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
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
.
l
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
.
NOTE
l
For RHEL 6, CentOS 6, and SLES 12, you can add IRQBALANCE_ARGS="--hintpolicy=exact" to
the end of the
/etc/sysconfig/irqbalance
file content to better balance interrupts.
l
To configure the irqbalance service in other OSs, refer to documents related to the OSs.
If the OS cannot find the service, it indicates that the OS does not use the irqbalance service
for balance interrupts. If the command can be run, check whether errors are reported after
running the command for restarting the irqbalance service.
l
If yes, go to
.
l
If no, no further action is required.

NOTE
If the ES3000 V5 hiodriver is used, certain operating systems such as SUSE Linux will record the
module verification failed
error in dmesg logs. This error message is a notification indicating that an
operating system detects a third-party driver with an unmatched signature. It does not affect services.
