Table 5.8 Example Of Interface Information About The Replaced Nic - Fujitsu PRIMEQUEST 2000 Series Administration Manual

CHAPTER 5 Hot Maintenance in Red Hat Enterprise Linux 7
5.7 Hot Replacement of PCI Express Cards
will be referenced and otherwise used. Below, the slot number confirmed in step 1 is shown at <slot
number> in the directory path in the following format, where the directory is the operational target.
/sys/bus/pci/slots/<slot number>
To disable a PCI Express card and make it ready for removal, write "0" to the "power" file in the
directory corresponding to the target slot. The LED turns off. The interface (ethX) is removed at the
same time.
# echo 0 > /sys/bus/pci/slots/<slot number>/power
6. Save the interface configuration file.
Save all the interface configuration files that you checked in step 2 by executing the following command.
Configuration scripts may reference the contents of files in /etc/sysconfig/network-scripts. For this reason,
create a save directory and save these files to the directory so that the configuration scripts will not
reference them.
# cd /etc/sysconfig/network-scripts
# mkdir temp
# mv ifcfg-ethX temp
(following also executed for bonding configuration)
# mv ifcfg-bondX temp
7. Physically replace the NIC by using MMB Maintenance Wizard. This step is performed by the field
engineer in charge of your system.
For details on the operation of replacement, see step 1 to 7 of 'Operation for Hot replacement of PCI
Express card by Maintenance Wizard' in
8. Power on the PCI Express slot.
See 'Powering on and off PCI Express slots' in
9. Check whether there is an error in added FC card by MMB Maintenance Wizard.
This step is performed by the field engineer in charge of your system.
For details on the operation of replacement, see step 8 to 11 of 'Operation for Hot replacement of PCI
Express card by Maintenance Wizard' in
10. Collect the information associated with an interface on the replaced NIC.
An interface (ethX) is created for the replaced NIC at the power-on time. Make a table with information
about each interface created for the replaced NIC. Such information includes the interface name,
hardware address, and bus address. Use the bus address confirmed in step 1 and the same procedure
as in step 2.
Interface name
eth1
eth0
...
Confirm that a new hardware address is defined for the bus address. Also confirm that the assigned
interface name is the same as that before the NIC replacement.
Note
The correspondence between the bus address and interface name may be different from that before NIC
replacement. In such cases, just proceed with the work. This is explained in step 13.
11. Deactivate each newly created interface.
The interfaces created for the replaced NIC may be active because power is on to the PCI Express slot.
In such cases, you need to deactivate them before changing the interface configuration file.
Execute the following command for all the interface names confirmed in step 11.
Example: eth0
# /sbin/ifconfig eth0 down
12. Confirm the correspondence between the interface names before and after the NIC replacement.
From the interface information created before and after the NIC replacement in steps 2 and 10, confirm
the correspondence between the interface names before replacement and the new interface names.
a. Confirm the correspondence between the bus address and interface name on each line in the table
created in step 2.
b. Likewise, confirm the correspondence between the bus addresses and interface names in the table
created in step 10.
