Table 7.3 Example Of Interface Information About Interfaces After Replacement; Operation After Iou Hot Replacement - Fujitsu PRIMEQUEST 2000 Series Administration Manual

CHAPTER 7 PCI Card Hot Maintenance in SUSE Linux Enterprise Server 12
7.4 Hot replacement of IOU
13. Execute "/opt/FJSVdr-util/sbin/dr add IOU" command on the shell of OS.
The IOU to be removed will turn on.
Example: turning on IOU 3
# /opt/FJSVdr-util/sbin/dr add IOU3
#

7.4.3 Operation after IOU hot replacement

Note
If SVAgent is installed in the partition, perform below command with root privilege.
# /usr/sbin/srvmagt restart
NIC on the IOU (including onboard NIC)
1. Collect the information associated with NIC on the replaced IOU.
An interface (ethX) is created for the replaced NIC. Make a table with information including the interface
name, hardware address, bus address, and location of the interface made corresponding to NIC mounted
on replaced according to step1 and step 2 of the section
interface name, hardware address and PCI bus address may change before and after replacing IOU.

TABLE 7.3 Example of interface information about interfaces after replacement

Note
If you use standard name for interfaces, you should consider the following.
- The theory of assignment of PCI bus address is different between BIOS and operating system. Then,
PCI bus address which is different from that one assigned before replacement is assigned when hot
replacement, and name of interface is changed.
- After hot replacement, if the partition is reboot, PCI bus address is reassigned. So, new interface
name becomes the name which is not identical with PCI Bus address.
- Not to change the interface name of upper driver or network script and so on, you must do setting that
interface name is assigned by the form of ethX after install. For details, see SUSE, Inc's Administration
guide.
2. Edit the saved interface configuration file.
Write a new hardware address to replace the old one. In "HWADDR," set the hardware address of the
replaced NIC in
after NIC replacement. If the interface name is changed, change also the interface name. (in this case,
you must change file name itself.) Also, for SLAVE under bonding, the file contents are partly different,
but the lines to be set are the same.
Example:
DEVICE=eth0
NM_CONTROLLED=no
BOOTPROTO=static
HWADDR=2c:d4:44:f1:44:d2
BROADCAST=192.168.16.255
IPADDR=192.168.16.1
NETMASK=255.255.255.0
NETWORK=192.168.16.0
ONBOOT=yes
TYPE=Ethernet
Do this editing for all the saved interfaces except for the interface with no change of hardware address
and interface name.
3. Restore the saved interface configuration file to the original file.
Restore the interface configuration file saved to the save directory to the original file by executing the
following command.
Hardware address
2c:d4:44:f1:44:d2
2c:d4:44:f1:44: d3
