Table 4.9 Example Of Entered Values Corresponding To The Interface Names Before And After Nic Replacement - Fujitsu PRIMEQUEST 2000 Series Administration Manual

CHAPTER 4 PCI Card Hot Maintenance in Red Hat Enterprise Linux 6
4.6 Hot Replacement of PCI Express Cards
d. In the table created in step 11, enter values corresponding to the interface names before and after the
NIC replacement.

TABLE 4.9 Example of entered values corresponding to the interface names before and after NIC replacement

Interface name
After replacement
(-> Before replacement)
eth1 (-> eth0)
eth0 (-> eth1)
...
15. If an interface name is switched before and after the NIC replacement, make the interface name
correspond to the same bus address as before the NIC replacement by using the following procedure.
Note
Confirm that the interface name is the same before and after the NIC replacement. Then, proceed to step
15.
a. Power off the PCI Express slot again.
Repeat the process done in step 5 to power off the PCI Express slot.
b. Correct the interface name that is not the same before and after the NIC replacement in the entries of
the udev function rule file, /etc/udev/rules.d/70-persistent-net.rules. Make the interface name the
same as before the NIC replacement.

(eth1, the name after replacement, has been corrected to eth0, the name before replacement.)
# PCI device 0x****:0x**** (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ¥
ATTR{address}=="00:0e:0c:70:c3:40", ATTR{type}=="1", ¥
KERNEL=="eth*", NAME="eth0"
# PCI device 0x****:0x**** (e1000)

ATTR{address}=="00:0e:0c:70:c3:41", ATTR{type}=="1", ¥
KERNEL=="eth*", NAME="eth1"

The ¥ at the end of a line indicates that there is no line feed.
c. Reflect the edited rules again.
Repeat the process done in step 9 to reflect the rules.
# udevadm control ––reload-rules
d. Power on the PCI Express slot.
Repeat the process done in step 10 to power on the PCI Express slot.
The interfaces created for the replacement NIC may be active because power is on to the PCI
Express slot. At this stage, since we recommend proceeding with the work with the interface on the
replaced NIC deactivated, repeat the operation in step 12.
e. Collect the information about interfaces on the NIC again, and create a table.
Use the same procedure as in step 2 to update the interface name information in the table from step
13 showing the correspondence of the interface before and after NIC replacement.
