CHAPTER 5 PCI Card Hot Maintenance in SUSE Linux Enterprise Server 11
5.3 Removing PCI Express cards
# /sbin/vconfig rem ethX.Y
[For the interface under bonding]
If the bonding device is operating in mode 1, use the following steps for safety purposes on the SLAVE
interface to be removed to exclude it from operation. In any other mode, removing it immediately should
not cause any problems. Confirm that the SLAVE interface is the interface currently being used for
communication.
# cat /sys/class/net/bondY/bonding/active_slave
If the displayed interface name corresponds to the SLAVE interface to be removed, execute the following
command to switch to communicating now with the other SLAVE interface.
# /sbin/ifenslave -c bondY ethZ
(ethZ: bondY-configured interface not subject to hot
replacement)
Finally, remove the SLAVE interface being replaced, from the bonding configuration. Immediately after
being removed, the interface is automatically no longer used.
# /sbin/ifenslave -d bondY ethX
To remove the interfaces, including the bonding device, deactivate them collectively by executing the
following command.
# /sbin/ifdown bondY
6. Power off the PCI slot.
See 'Powering on and off PCI Express slots' in
7. After taking of all cables connected to the NIC, remove the NIC from the PCI Express slot.
8. Remove the interface configuration file.
Delete the configuration files of all the interfaces confirmed in step 2, by executing the following command.
# rm /etc/sysconfig/network/ifcfg-ethX
When deleting a bonding device, also delete the related bonding items (ifcfg-bondY files).
9. Edit the settings in the udev function rule file.
The entries of the interface assigned to the removed NIC still remain in the udev function rule file,
/etc/udev/ rules.d/70-persistent-net.rules. Leaving the entries will affect the determination of interface
names for replacement cards or added cards in the future. For this reason, delete or comment out those
entries.
The following example shows editing of the udev function rule file, /etc/udev/rules.d/70-persistent-
net.rules. (In this example, the file is edited when the eth10 interface is removed.)
