Hi
Given:
OS: SLES 11 SP3 (64b)
HW: Server with eth0,eth1,eth2,eth3
Task:
Install via network and reconfigure configure eth1 -> eth0 , eth2 -> eth1 and create a bond0 interface build of eth0,eth1
Note
- The mac address are known.
- 2 adapters are not used.
Autoyast file:
</networking>
<interfaces config:type="list">
<interface>
yes
mode=active-backup miimon=1000 arp_ip_target=10.11.0.1
eth0
eth1
<bootproto>static</bootproto>
<device>bond0</device>
<ipaddr>10.11.14.2</ipaddr>
<netmask>255.255.0.0</netmask>
<prefixlen>16</prefixlen>
<startmode>auto</startmode>
<usercontrol>no</usercontrol>
</interface>
<interface>
<bootproto>none</bootproto>
<device>eth0</device>
<startmode>auto</startmode>
<usercontrol>no</usercontrol>
</interface>
<interface>
<bootproto>none</bootproto>
<device>eth1</device>
<startmode>auto</startmode>
<usercontrol>no</usercontrol>
</interface>
</interfaces>
<managed config:type="boolean">false</managed>
<net-udev config:type="list">
<rule>
<name>eth0</name>
<rule>ATTR{address}</rule>
<value>34:40:B5:C8:E2:42</value>
</rule>
<rule>
<name>eth1</name>
<rule>ATTR{address}</rule>
<value>34:40:B5:C8:E2:46</value>
</rule>
</net-udev>
</networking>
Problem:
After installation i have
$ ifconfig -a | grep -E "eth|bond"
- eth2
- eth3
- eth4
- eth5
But no bond device.
Analyse:
I checked the /etc/udev/rules.d/70-persistent-net.rules and see
...
# Generated by autoyast
# program run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="34:40:B5:C8:E2:42", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="34:40:B5:C8:E2:46", NAME="eth1"
# PCI device 0x19a2:0x0710 (be2net)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="34:40:b5:c8:e2:44", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
# PCI device 0x19a2:0x0710 (be2net)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="34:40:b5:c8:e2:42", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"
# PCI device 0x19a2:0x0710 (be2net)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="34:40:b5:c8:e2:46", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4"
# PCI device 0x19a2:0x0710 (be2net)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="34:40:b5:c8:e2:40", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5"
...
So the adapters will be added for whatever reason again and we end up in eth2,3,3,5 and eth0,eth1 are not available.
The not so fun thing is that the even after fixing the /etc/udev/rules.d/70-persistent-net.rules it will be regenerated. ( FROM WHERE?)
Note:
A via yast generate network section looks like:
<interfaces config:type="list">
<interface>
yes
mode=active-backup miimon=1000 arp_ip_target=10.11.0.1
eth0
eth1
<bootproto>static</bootproto>
<device>bond0</device>
<ipaddr>10.11.14.2</ipaddr>
<netmask>255.255.0.0</netmask>
<prefixlen>16</prefixlen>
<startmode>auto</startmode>
<usercontrol>no</usercontrol>
</interface>
<interface>
<bootproto>none</bootproto>
<device>eth0</device>
<name>Emulex OneConnect 10Gb NIC (be3)</name>
<startmode>auto</startmode>
<usercontrol>no</usercontrol>
</interface>
<interface>
<bootproto>none</bootproto>
<device>eth1</device>
<name>Emulex OneConnect 10Gb NIC (be3)</name>
<startmode>auto</startmode>
<usercontrol>no</usercontrol>
</interface>
<net-udev config:type="list">
<rule>
<name>eth0</name>
<rule>ATTR{address}</rule>
<value>34:40:b5:c8:e2:42</value>
</rule>
<rule>
<name>eth1</name>
<rule>ATTR{address}</rule>
<value>34:40:b5:c8:e2:46</value>
</rule>
So no real difference except that i did not provide the <name>..</name> in my profile.
Any hints ?

The docu form https://www.suse.com/documentation/sles11/singlehtml/book_autoyast/book_auto... is not very helpful.
