Step 6

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 swap:

l

For RHEL 6 or CentOs 6, run

service irqbalance restart

.

l

For SLES 11, run

service irq_balancer restart

.

l

For SLES 12, RHEL 7 or Oracle 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.

l

You have installed the Windows tool package. For details, see

3.7.2 Installing the Tool

Package (Windows)

Procedure

Windows GUI

Step 1

Log in to the OS as an administrator or administrator group member.

Step 2

Stop all services accessing the ES3000 V5 SSD.

Step 3

Double-click the

HioadmGUI_DotNet_x.0.exe

file in the tool installation directory to

display the Windows GUI window, as shown in

l

If the .NET Framework version is 2.0 or 3.5, double-click the

HioadmGUI_DotNet_2.0.exe

file in the tool installation directory.

l

If the .NET Framework version is 4.0 or 4.5, double-click the
