Notifying the OS
Step 1
Log in to the OS as the root user.
Step 2
Stop all services accessing the ES3000 V3 disk.
Step 3
If you have used the
mount
command to attach the disk partitions to certain paths, use the
umount
command to detach the partitions.
Step 4
Run the following command to notify the OS to take power off the device.
$slot
in the commands indicates the actual number of the slot where the device is attached.
echo 0 > /sys/bus/pci/slots/$slot/power
Step 5
if the OS uses the irqbalance service to balance CPU interrupts, restart the service by using
one of the following commands after performing a hot plug:
l
For Red Hat 6 or CentOs 6, run
service irqbalance restart
.
l
For SLES 11, run
service irq_balancer restart
.
l
For SLES 12 or Red Hat 7, run
systemctl restart irqbalance.service
.
NOTE
l
For Red Hat 6, CentOs 6, or 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.
