hardware address of other interfaces by repeating the operation with the same command. The
following table lists examples of descriptions.

...
The step above is used in creating the correspondence table in step 12. Prepare a table here so that
you can reference it later.
Note
In a replacement due to a device failure, the information in the table showing the correspondence
between the interface and the hardware address, bus address, and slot number may be inaccessible
depending on the failure condition. We strongly recommend that a table showing the correspondence
between the interface and the hardware address, bus address, and slot number be created for all
interfaces at system installation.
3. Execute the higher-level application processing required before NIC replacement.
Stop all access to the interface as follows. Stop the application that was confirmed in step 2 as using the
interface, or exclude the interface from the target of use by the application.
4. Deactivate the NIC.
Execute the following command to deactivate all the interfaces that you confirmed in step 2.
The applicable command depends on whether the target interface is a single NIC interface or the SLAVE
interface of a bonding device.
[For a single NIC interface]
# /sbin/ifdown ethX
If the single NIC interface has a VLAN device, you also need to remove the VLAN interface. Perform the
following operations (before deactivating the real interface).
# /sbin/ifdown ethX.Y
# /sbin/vconfig rem ethX.Y
[For the SLAVE interface of a bonding device]
If the bonding device is operating in mode 1, use the following steps to exclude SLAVE interface to be
replaced from the bonding configuration. In any other mode, removing it immediately should not cause
any problems.
Confirm that the SLAVE interface to be replaced is the interface currently being used for communication.
First, confirm the interface currently being used for communication by executing the following command.
# cat /sys/class/net/bondY/bonding/active_slave
If the displayed interface matches the SLAVE interface being replaced, execute the following command to
switch the current communication interface to another SLAVE interface.
# /sbin/ifenslave -c bondY ethZ
(ethZ: Interface that composes bondY and does not perform
hot replacement)
Finally, remove the SLAVE interface being replaced, from the bonding configuration. Immediately after
being removed, the interface is automatically no longer used.
# /sbin/ifenslave -d bondY ethX
5. Power off the PCI Express slot.
- For the partition with Dynamic Reconfiguration utility installed
Execute /opt/FJSVdr-util/sbin/dr rm pcie<slot number> command on the shell of OS.
The PCI Express card is disabled and has become to be ready for removal. The LED turns off.
Example: Making the PCI Express slot with PCI Express slot number 20 power off
# /opt/FJSVdr-util/sbin/dr rm pcie20
This operation removes the device associated with the relevant adapter from the system.
- For the partition without Dynamic Reconfiguration utility installed
Confirm that the /sys/bus/pci/slots directory contains a directory for the target slot information, which
