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

Figure 6.4 Addition of a virtual interface for making the added NICs (ethX,ethY) redundant

For Fast switching mode

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

    For details, see "PCI card replacement procedure in detail" in "PRIMEQUEST 1000 Series Administration Manual".

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

  2. Add a NIC to the PCI slot.

  3. Turn on power to the PCI slot.

    For details, see "PCI card replacement procedure in detail" in "PRIMEQUEST 1000 Series Administration Manual".

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

  4. Check that the entry information related to the NIC after addition is added into the rule file /etc/udev/rules.d/70-persistent-net.rules for the udev function of the operating system.

    # cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules

6.4.2.3 Swapping procedure

This section describes the procedure for swapping a NIC whose virtual interface makes it redundant.

Figure 6.6 Swapping a NIC whose virtual interface makes it redundant (ethX)

For Fast switching mode

  1. Prepare for swapping a card.

    1) From the virtual interface definition, temporarily delete the definition information about the NIC to be swapped.

    # /opt/FJSVhanet/usr/sbin/hanetnic delete -n shaX -i ethX

    2) Enter the dsphanet command to confirm that the device status of the NIC is "CUT".

    # /opt/FJSVhanet/usr/sbin/dsphanet
[IPv4,Patrol / Virtual NIC]
 Name       Status   Mode CL  Device
+----------+--------+----+----+------------------------------------------------+
 shaX       Active    t   OFF  ethX(CUT),ethY(ON)

    3) Deactivate the NIC.

    # /sbin/ifdown ethX

    4) Back up the network configuration file of the interface.

    # cd /etc/sysconfig/network-scripts
# mkdir temp
# mv ifcfg-ethX temp

  2. Turn off power to the target PCI slot.

    The interface (ethX) is deleted when power is turned off. For details, see "PCI card replacement procedure in detail" in "PRIMEQUEST 1000 Series Administration Manual".

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

  3. Swap the NIC in the PCI slot.

  4. Delete the entry information of the deleted interface from the rule file /etc/udev/rules.d/70-persistent-net.rules for the udev function of the operating system.

    # vi /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
  ...
  ...
# PCI device 0xXXXX:0xXXXX (e1000)
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", \
    ATTR{address}=="XX:XX:XX:XX:XX:XX", ATTR{type}=="1", KERNEL=="eth*", NAME="ethX"

  5. Turn on power to the PCI slot.

    For details, see "PCI card replacement procedure in detail" in "PRIMEQUEST 1000 Series Administration Manual".

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

  6. If the interface (ethX) created by turning on the power for the swapped NIC is activated, deactivate it..

    # /sbin/ifconfig ethX down

  7. Check that the entry information related to the NIC after swap is added into the rule file /etc/udev/rules.d/70-persistent-net.rules for the udev function of the operating system.

    # cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
  ...
  ...

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",  \
ATTR{address}=="ZZ:ZZ:ZZ:ZZ:ZZ:ZZ", ATTR{type}=="1", KERNEL=="eth*", NAME="ethX"

  8. If interface names are switched before and after swapping NICs, turn off the power of the PCI slot. Then edit the interface name in the rule file for udev function and turn on the power of the PCI slot again. For details, see "Network card replacement procedure" in "PRIMEQUEST 1000 Series Administration Manual".

  9. Check the hardware address.

    Check that the hardware address (HWaddr) of the created interface on the swapped NIC from the rule file /etc/udev/rules.d/70-persistent-net.rules for the udev function of the operating system.

  10. Perform post-swap processing.

    1) Change the HWADDR in the interface setting file, which was backed up, to the hardware address of the swapped NIC that was checked in Step 9.

    # cd /etc/sysconfig/network-scripts
# mv temp/ifcfg-ethX .
# rmdir temp

    ifcfg-ethX (Swapped NIC)

    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) Activate the swapped NIC.

    # /sbin/ifup ethX

    3) Restore the NIC definition that was temporarily deleted prior to swapping in 1) of Step 1.

    # /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 / Virtual NIC]
 Name       Status   Mode CL  Device
+----------+--------+----+----+------------------------------------------------+
 shaX       Active    t   OFF  ethY(ON),ethX(ON)

For NIC switching mode

  1. Prepare for swapping a card.

    1) Stop HUB monitoring.

    # /opt/FJSVhanet/usr/sbin/hanetpoll off

    2) Stop standby patrol monitoring. If the standby patrol function is not used, skip this step.

    # /opt/FJSVhanet/usr/sbin/stpptl -n shaY

    3) Enter the dsphanet command to check the status of the NIC to be swapped. The NIC must be in a different state from that of an active NIC (the NIC must be in the "OFF" or "STOP" state). If the NIC is active, follow Step 4) to switch its state to standby.

    # /opt/FJSVhanet/usr/sbin/dsphanet
[IPv4,Patrol / Virtual NIC]
 Name       Status   Mode CL  Device
+----------+--------+----+----+------------------------------------------------+
 shaX       Active    d   OFF   ethX(ON),ethY(OFF)

    4) If the NIC is an active NIC, switch its state to standby. After the switch, enter the dsphanet command to confirm that the NIC is a standby NIC(OFF).

    # /opt/FJSVhanet/usr/sbin/hanetnic change -n shaX

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

  6. If the interface (ethX) created by turning on the power for the swapped NIC is activated, deactivate it.

    # /sbin/ifconfig ethX down

  7. Check that the entry information related to the NIC after swap is added into the rule file /etc/udev/rules.d/70-persistent-net.rules for the udev function of the operating system.

    # cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
  ...
  ...
# PCI device 0xXXXX:0xXXXX (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",  \
ATTR{address}=="ZZ:ZZ:ZZ:ZZ:ZZ:ZZ", ATTR{type}=="1", KERNEL=="eth*", NAME="ethX"

  8. If interface names are switched before and after swapping NICs, turn off the power of the PCI slot. Then edit the interface name in the rule file for udev function and turn on the power of the PCI slot again. For details, see "Network card replacement procedure" in "PRIMEQUEST 1000 Series Administration Manual".

  9. Check the hardware address.

    Check that the hardware address (HWaddr) of the created interface on the swapped NIC from the rule file /etc/udev/rules.d/70-persistent-net.rules for the udev function of the operating system.

  10. Perform post-swap processing.

    1) Change the HWADDR in the interface setting file, which was backed up, to the hardware address of the swapped NIC that was checked in Step 9.

    # cd /etc/sysconfig/network-scripts
# mv temp/ifcfg-ethX .
# rmdir temp

    ifcfg-ethX (Swapped NIC)

    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) Set the state of the swapped NIC to that of a standby NIC of GLS. Confirm that an IPv4 address is not assigned and the "UP" and "NOARP" flags are set. If an IPv6 address is assigned to the virtual interface, this step is not necessary.

    # /sbin/ifconfig ethX 0 -arp up
    # /sbin/ifconfig ethX
ethX      Link encap:Ethernet  HWaddr ZZ:ZZ:ZZ:ZZ:ZZ:ZZ
          inet6 addr: fe80::XXXXXXXXXXXXXXXX/64 Scope:Link
          UP BROADCAST NOARP MULTICAST  MTU:1500  Metric:1

    3) If necessary, fail-back the NIC.

    # /opt/FJSVhanet/usr/sbin/hanetnic change -n shaX

    4) Start standby patrol monitoring. If the standby patrol function is not used, skip this step.

    # /opt/FJSVhanet/usr/sbin/strptl -n shaY

    5) Restart HUB monitoring.

    # /opt/FJSVhanet/usr/sbin/hanetpoll on

    6) Restart interface status monitoring.

    # /bin/rm /var/opt/FJSVhanet/tmp/disable_watchif

For Virtual NIC mode

[IPv4,Patrol / Virtual NIC]
 Name       Status   Mode CL  Device
+----------+--------+----+----+------------------------------------------------+
 shaX       Active    v   OFF  ethX(CUT),ethY(ON)

    4) Deactivate the NIC.

    # /sbin/ifdown ethX

    5) Back up the network configuration file of the interface.

    # cd /etc/sysconfig/network-scripts
# mkdir temp
# mv ifcfg-ethX temp

  2. Turn off power to the target PCI slot.

    The interface (ethX) is deleted when power is turned off. For details, see "PCI card replacement procedure in detail" in "PRIMEQUEST 1000 Series Administration Manual".
