Make sure that power to the target PCI slot is off.
For details, see the manuals for PRIMEQUEST. Note that <BUS-number_slot-number> is used for RHEL5 and SLES10 instead of <slot-number>. The same applies hereafter.
# cat /sys/bus/pci/slots/"<slot-number>"/power 0 |
Add a NIC to the PCI slot.
Turn on power to the PCI slot.
For details, see the manuals for PRIMEQUEST.
# echo 1 > /sys/bus/pci/slots/"<slot-number>"/power |
Check the hardware address.
An interface (ethX) is created for the added NIC when power is turned on. Execute the ifconfig (8) command to check the hardware address of the added NIC (HWaddr). To add more NICs, repeat steps 2 to 5.
Perform post-addition processing.
1) The added NICs must be activated at system startup. For this purpose, make the settings shown below in each interface setting file (/etc/sysconfig/network-scripts/ifcfg-eth<x>). Specify the hardware address that was checked in Step 5 for "HWADDR". Also specify "HOTPLUG=no".
ifcfg-ethX
DEVICE=ethX BOOTPROTO=static HWADDR=XX:XX:XX:XX:XX:XX HOTPLUG=no BROADCAST=XXX.XXX.XXX.XXX IPADDR=XXX.XXX.XXX.XXX NETMASK=XXX.XXX.XXX.XXX NETWORK=XXX.XXX.XXX.XXX ONBOOT=yes TYPE=Ethernet |

For details, see the manuals for PRIMEQUEST.
# echo 1 > /sys/bus/pci/slots/"<slot-number>"/power |
Check the hardware address.
An interface (ethX) is created for the added NIC when power is turned on. Execute the ifconfig (8) command to check the hardware address of the added NIC (HWaddr). To add more NICs, repeat steps 2 to 5.
Perform post-addition processing.
1) The current NIC must be activated and the standby NIC must be deactivated at system startup. For this purpose, make the settings shown below in each interface setting file (/etc/sysconfig/network-scripts/ifcfg-eth<x>). Specify the hardware address that was checked in Step 5 for "HWADDR". Specify "HOTPLUG=no" for both NICs.
ifcfg-ethX (Primary interface)
DEVICE=ethX BOOTPROTO=static HWADDR=XX:XX:XX:XX:XX:XX HOTPLUG=no BROADCAST=XXX.XXX.XXX.XXX IPADDR=XXX.XXX.XXX.XXX NETMASK=XXX.XXX.XXX.XXX NETWORK=XXX.XXX.XXX.XXX ONBOOT=yes TYPE=Ethernet |
ifcfg-ethY (Secondary interface)
DEVICE=ethY HWADDR=YY:YY:YY:YY:YY:YY HOTPLUG=no ONBOOT=yes TYPE=Ethernet |
2) Add the added NIC to the /etc/modprobe.conf file, which allows the NIC to be associated with the driver. The following is an example of /etc/modprobe.conf.

# /sbin/modprobe -r shpchp |
4) Change the interface names of the added NICs to the names specified in the interface setting files (/etc/sysconfig/network-scripts/ifcfg-eth<x>). Specify the same interface names and MAC addresses in the nameif (8) command as those in "DEVICE" and "HWADDR" in the ifcfg-ethX and ifcfg-ethY files that were set in 1) of step 6. When the nameif (8) command is executed, the specified interface must be deactivated.
# /sbin/nameif ethX XX:XX:XX:XX:XX:XX # /sbin/nameif ethY YY:YY:YY:YY:YY:YY |
5) If necessary, specify subnet mask information for the virtual interface.
# /opt/FJSVhanet/usr/sbin/hanetmask create -i network_address -m netmask |

Collect the current hardware information
When using RHEL5, take the following steps to collect hardware information. For details, see the manuals for PRIMEQUEST.
# /sbin/kudzu # cp /etc/modprobe.conf.bak /etc/modprobe.conf # mv /etc/sysconfig/network-scripts/ifcfg-ethX.bak \ /etc/sysconfig/network-scripts/ifcfg-ethX |
Check the hardware address.
An interface (ethX) is created for the swapped NIC when power is turned on. Execute the ifconfig (8) command to check the hardware address of the swapped NIC (HWaddr).
Perform post-swap processing.
1) Change the specified value of "HWADDR" in the interface setting file (/etc/sysconfig/network-scripts/ifcfg-eth<x>) to the hardware address of the swapped NIC that was checked in Step 6.
ifcfg-ethX
DEVICE=ethX BOOTPROTO=static HWADDR=ZZ:ZZ:ZZ:ZZ:ZZ:ZZ HOTPLUG=no BROADCAST=XXX.XXX.XXX.XXX IPADDR=XXX.XXX.XXX.XXX NETMASK=XXX.XXX.XXX.XXX NETWORK=XXX.XXX.XXX.XXX ONBOOT=yes TYPE=Ethernet |
2) Change the interface name of the swapped NIC to the name specified in the interface setting file (/etc/sysconfig/network-scripts/ifcfg-eth<x>). Specify the same interface name and hardware address in the nameif (8) command as those in "DEVICE" and "HWADDR" in the ifcfg-ethX file that was set in 1) of step 6. When the nameif (8) command is executed, the specified interface must be deactivated.
# /sbin/nameif ethX ZZ:ZZ:ZZ:ZZ:ZZ:ZZ |
3) Restore the NIC definition that was temporarily deleted prior to swapping in 1) of Step 2).
# /opt/FJSVhanet/usr/sbin/hanetnic add -n shaX -i ethX |
4) Enter the dsphanet command to confirm that the device status of the swapped NIC is "ON".
# /opt/FJSVhanet/usr/sbin/dsphanet
[IPv4,Patrol]
Name Status Mode CL Device
+----------+--------+----+----+------------------------------------------------+
shaX Active t OFF ethX(ON),ethY(ON) |
5) Restore the PCI Hot Plug driver. If you have installed the PCI Hot Plug driver according to 1., execute the following command to remove it.
