4.3 Hot replacement of IOU
9. Execute "hotadd" command on MMB console.
Example: Adding IOU 3 to partition 1
Administrator > hotadd partition 1 IOU 3
Are you sure to continue adding IOU#3 to Partition#1? [Y/N]

DR operation start (1/3)
Assigning IOU#3 to partition#1 (2/3)
Power on IOU#3 (3/3)
Adding IOU#3 to Partition#1 has been completed successfully.
Administrator >
10. Perform "show dynamic_reconfiguration status" command and confirm below messages.
Example: When adding IOU3 to partition 1.
"Adding IOU#3 to Partition#1, completed." or "not executed."
11. Execute "/opt/FJSVdr-util/sbin/dr stat IOU" command
A list of IOU included in the partition is shown. Check that added IOU is shown.
Example: adding IOU 3
# /opt/FJSVdr-util/sbin/dr stat IOU
IOU0: empty
IOU1: empty
IOU2: empty
IOU3: offline
IOU added to partition is shown as offline state because it is power-off state at this time.
12. 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

4.3.3 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.

For replacing IOU itself, confirm that new hardware address is defined to NIC of onboard. Confirm that
the interface name used before replacing NIC is re-assigned. New PCI bus address may be assigned.
Also confirm that the relevant entries in the above-described table were automatically added to the udev
function rule file, /etc/udev/rules.d/70-persistent-net.rules.
For expanding or removing PCI Express card by replacing IOU, the number of entry in table increase or
decrease.
2. Deactivate each newly created interface.
The interfaces created for the replaced NIC may be active by turning on IOU. In such cases, you need to
deactivate them before changing the interface configuration file.
Execute the below command for all the interface names (including interfaces which are not actually
