4.5.1.1 Addition procedure

This section describes the procedure for adding NICs and creating a virtual interface to make the added NICs redundant.

[Figure 4.1 Addition of a virtual interface for making the added NICs (ethX,ethY) redundant]

For a Fast switching mode

1. Confirm that the PCI Hot Plug driver is installed.

If the PCI Hot Plug driver is not installed, install it according to "B.2.2 Installation of a PCI Hot Plug driver" of the "PRIMEQUEST 480/440 Operation Manual".

Confirmation procedure

# lsmod | grep shpchp
shpchp                203816  0

Installation procedure

# modprobe shpchp

2. Make sure that power to the target PCI slot is off.

For details, see "B.2.3.1 Checking the power status" of the "PRIMEQUEST 480/440 Operation Manual".

# cat /sys/bus/pci/slots/"<slot-number>"/power
0

3. Add a NIC to the PCI slot.

4. Turn on power to the PCI slot.

For details, see "B.2.3.2 Power-on and power-off procedures" of the "PRIMEQUEST 480/440 Operation Manual".

# echo 1 > /sys/bus/pci/slots/"<slot-number>"/power

5. 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.

6. 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

ifcfg-ethY

DEVICE=ethY
BOOTPROTO=static
HWADDR=YY:YY:YY:YY:YY:YY
HOTPLUG=no
BROADCAST=YYY:YYY:YYY:YYY
IPADDR=YYY:YYY:YYY:YYY
NETMASK=YYY:YYY:YYY:YYY
NETWORK=YYY:YYY:YYY:YYY
ONBOOT=yes
TYPE=Ethernet

2) Activate the added NICs.

# /sbin/ifup ethX
# /sbin/ifup ethY

3) If necessary, specify subnet mask information for the virtual interface.

# /opt/FJSVhanet/usr/sbin/hanetmask create -i network_address -m netmask

4) Make the virtual interface settings to make the NICs redundant.

# /opt/FJSVhanet/usr/sbin/hanetconfig create -n shaX -m t -i ipaddress -t ethX,ethY

5) Activate the virtual interface.

# /opt/FJSVhanet/usr/sbin/strhanet -n shaX

For a NIC switching mode

1. Confirm that the PCI Hot Plug driver is installed.

If the PCI Hot Plug driver is not installed, install it according to "B.2.2 Installation of a PCI Hot Plug driver" of the "PRIMEQUEST 480/440 Operation Manual".

Confirmation procedure

# lsmod | grep shpchp
shpchp                203816  0

Installation procedure

# modprobe shpchp

2. Make sure that power to the target PCI slot is off.

For details, see "B.2.3.1 Checking the power status" of the "PRIMEQUEST 480/440 Operation Manual".

# cat /sys/bus/pci/slots/"<slot-number>"/power
0

3. Add a NIC to the PCI slot.

4. Turn on power to the PCI slot.

For details, see "B.2.3.2 Power-on and power-off procedures" of the "PRIMEQUEST 480/440 Operation Manual".

# echo 1 > /sys/bus/pci/slots/"<slot-number>"/power

5. 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.

6. Perform post-addition processing.

1) The current NIC must be activated and the standby NIC must be deactivated at system startup. For this purpose, write each interface setting file (/etc/sysconfig/network-scripts/ifcfg-eth<x>) so that "ONBOOT=yes" is specified for the current NIC and "ONBOOT=no" is specified for the standby NIC. 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=no
TYPE=Ethernet

2) 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

3) If necessary, specify subnet mask information for the virtual interface.

# /opt/FJSVhanet/usr/sbin/hanetmask create -i network_address -m netmask

4) Make the virtual interface settings to make the NICs redundant.

# /opt/FJSVhanet/usr/sbin/hanetconfig create -n shaX -m d -i ipaddress1 -e ipaddress2 -t ethX,ethY

5) Specify hub monitoring destination information.

# /opt/FJSVhanet/usr/sbin/hanetpoll create -n shaX -p ipaddr1,ipaddr2

6) If necessary, set the standby patrol function.

# /opt/FJSVhanet/usr/sbin/hanetconfig create -n shaY -m p -t shaX

7) Restart GLS to enable the changed settings. This restart also activates the virtual interface and starts its monitoring.

# /opt/FJSVhanet/usr/sbin/resethanet -s
