For details, see the following manual:

Note that this section describes the operation when swapping IOU using the Dynamic Reconfiguration utility as an example.

Note

Make sure to check the procedure for the PCI Hot Plug in the latest manual before performing active maintenance for NIC.

For what active operation is enabled through PCI Hot Plug in the redundant line control function, see "6.3.2 Active maintenance of NIC."

6.4.2.1 Addition procedure

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 device is off.

    Example: When checking the power status of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr stat IOU
IOU"<slot-number>": online
IOU"<slot-number>": offline
IOU"<slot-number>": empty

  2. Add the target device.

    The device needs to be added by MMB. For details, see the following manual:

    • PRIMEQUEST 2000 Series

      "PCI Card Hot Maintenance in Red Hat Enterprise Linux 7" in "PRIMEQUEST 2000 Series Administration Manual"

  3. Turn on power to the added device.

    Example: When turning on the power of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr add IOU"<slot-number>"

  4. If the interface (ethX) for the added NIC, which was newly generated by turning on power, has been activated, deactivate it.

    # /usr/sbin/ip link set dev ethX down

  5. Check the hardware address.

    The interface (ethX) is created for the added NIC when power is turned on. Execute the ip(8) command to check the hardware address (link/ether) of the created interface. To add more NICs, repeat steps 1 to 5. 

    # /usr/sbin/ip addr show
N: ethX: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
    inet XXX.XXX.XXX.XXX/24 brd XXX.XXX.XXX.XXX scope global ethX
        valid_lft forever preferred_lft forever
    inet6 fe80::XXXXXXXXXXXXXXXX/64 scope link
        valid_lft forever preferred_lft forever

  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". In addition, specify "HOTPLUG=no" and "ONBOOT=yes" in the interface setting files of NICs for redundancy.

    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

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 (The interface name of the target NIC is ethX).

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

    2) Enter the dsphanet command to confirm that the device status of the target NIC (interface name: ethX) 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 interface of the target 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 device.

    The interface (ethX) is deleted when power is turned off.

    Example: When turning off the power of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr rm IOU"<slot-number>"

  3. Swap the target device.

    The device needs to be swapped by MMB. For details, see the following manual:

    • PRIMEQUEST 2000 Series

      "PCI Card Hot Maintenance in Red Hat Enterprise Linux 7" in "PRIMEQUEST 2000 Series Administration Manual"

  4. Turn on power to the target device.

    Example: When turning on the power of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr add IOU"<slot-number>"

  5. If the interface (ethX) for the swapped NIC, which was newly generated by turning on power, has been activated, deactivate it.

    # /usr/sbin/ip link set dev ethX down

  6. Check the hardware address.

    The interface (ethX) is created for the added NIC when power is turned on. Execute the ip(8) command to check the hardware address (link/ether) of the created interface. 

    # /usr/sbin/ip addr show
N: ethX: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
    inet XXX.XXX.XXX.XXX/24 brd XXX.XXX.XXX.XXX scope global ethX
        valid_lft forever preferred_lft forever
    inet6 fe80::XXXXXXXXXXXXXXXX/64 scope link
        valid_lft forever preferred_lft forever

  7. Change the HWADDR in the backed up interface setting file to the hardware address of the swapped NIC that was checked in step 6.

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

    ifcfg-ethX (Swapped NIC)

    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

  8. If interface names are switched before and after swapping NICs, turn on the power of the target device again.

    For details, see the following manual:

    • PRIMEQUEST 2000 Series

      "PCI Card Hot Maintenance in Red Hat Enterprise Linux 7" in "PRIMEQUEST 2000 Series Administration Manual"

  9. Perform post-swap processing.

    1) Activate the interface of the swapped NIC.

    # /sbin/ifup ethX

    2) Restore the NIC (interface name: ethX) that was temporarily deleted prior to swapping in 1) of step 1.

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

    3) Enter the dsphanet command to confirm that the device status of the swapped NIC (interface name: ethX) 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 (Interface name: ethX) 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
    # /opt/FJSVhanet/usr/sbin/dsphanet
[IPv4,Patrol / Virtual NIC]
 Name       Status   Mode CL  Device
+----------+--------+----+----+------------------------------------------------+
 shaX       Active    d   OFF   ethX(OFF),ethY(ON)

    5) Stop interface status monitoring.

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

    6) Deactivate the interface of the target NIC.

    # /sbin/ifdown ethX

    7) 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 device.

    The interface (ethX) is deleted when power is turned off.

    Example: When turning off the power of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr rm IOU"<slot-number>"

  3. Swap the target device.

    The device needs to be swapped by MMB. For details, see the following manual:

    • PRIMEQUEST 2000 Series

      "PCI Card Hot Maintenance in Red Hat Enterprise Linux 7" in "PRIMEQUEST 2000 Series Administration Manual"

  4. Turn on power to the target device.

    Example: When turning on the power of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr add IOU"<slot-number>"

  5. If the interface (ethX) for the swapped NIC, which was newly generated by turning on power, has been activated, deactivate it.

    # /usr/sbin/ip link set dev ethX down

  6. Check the hardware address.

    The interface (ethX) is created for the added NIC when power is turned on. Execute the ip(8) command to check the hardware address(link/ether) of the created interface.

    # /usr/sbin/ip addr show
N: ethX: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
    inet XXX.XXX.XXX.XXX/24 brd XXX.XXX.XXX.XXX scope global ethX
        valid_lft forever preferred_lft forever
    inet6 fe80::XXXXXXXXXXXXXXXX/64 scope link
        valid_lft forever preferred_lft forever

  7. Change the HWADDR in the backed up interface setting file to the hardware address of the swapped NIC that was checked in step 6.

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

    ifcfg-ethX (Swapped NIC)

    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

  8. If interface names are switched before and after swapping NICs, turn on the power of the target device again.

    For details, see the following manual:

    • PRIMEQUEST 2000 Series

      "PCI Card Hot Maintenance in Red Hat Enterprise Linux 7" in "PRIMEQUEST 2000 Series Administration Manual"

  9. Perform post-swap processing.

    1) Set the state of the swapped NIC to that of a standby NIC of GLS.

    The procedure varies depending on whether or not the IP address set to the virtual interface is only an IPv6 address.

    • If an IPv4 address is set to the virtual interface

      Confirm that an IPv4 address is not assigned and the "UP" and "NOARP" flags are set.

      # /usr/sbin/ip link set dev ethX arp off

    • If an only IPv6 address is set the virtual interface

      Confirm that the "UP" flag is set.

      # /usr/sbin/ip link set dev ethX up
# /usr/sbin/ip addr show ethX
N: ethX: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000

    Information

    If an only IPv6 address is set, when executing the dsphanet command right after executing the above commands, the available state "ON" is displayed for the both devices. This is a temporary state and it does not affect the system because the state will become a proper state by performing the following steps.

    2) If necessary, fail-back the NIC.

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

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

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

    4) Restart HUB monitoring.

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

    5) Restart interface status monitoring.

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

For Virtual NIC mode

  1. Prepare for swapping a card.

    1) Stop network monitoring.

    # /opt/FJSVhanet/usr/sbin/hanetpathmon off

    2) From the virtual interface definition, temporarily delete the definition information about the NIC to be swapped (The interface name of the target NIC is ethX).

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

    3) Enter the dsphanet command to confirm that the device status of the target NIC (interface name: ethX) is "CUT".

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

    4) Deactivate the interface of the target 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 device.

    The interface (ethX) is deleted when power is turned off.

    Example: When turning off the power of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr rm IOU"<slot-number>"

  3. Swap the target device.

    The device needs to be swapped by MMB. For details, see the following manual:

    • PRIMEQUEST 2000 Series

      "PCI Card Hot Maintenance in Red Hat Enterprise Linux 7" in "PRIMEQUEST 2000 Series Administration Manual"

  4. Turn on power to the target device.

    Example: When turning on the power of IOU using the Dynamic Reconfiguration utility

    # /opt/FJSVdr-util/sbin/dr add IOU"<slot-number>"

  5. If the interface (ethX) for the swapped NIC, which was newly generated by turning on power, has been activated, deactivate it.

    # /usr/sbin/ip link set dev ethX down

  6. Check the hardware address.

    The interface (ethX) is created for the added NIC when power is turned on. Execute the ip(8) command to check the hardware address(link/ether) of the created interface.

    # /usr/sbin/ip addr show
N: ethX: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
    inet XXX.XXX.XXX.XXX/24 brd XXX.XXX.XXX.XXX scope global ethX
        valid_lft forever preferred_lft forever
    inet6 fe80::XXXXXXXXXXXXXXXX/64 scope link
        valid_lft forever preferred_lft forever

  7. Change the HWADDR in the backed up interface setting file to the hardware address of the swapped NIC that was checked in step 6.

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

    ifcfg-ethX (Swapped NIC)

    DEVICE=ethX
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
ONBOOT=yes
DEVICETYPE=hanet

  8. If interface names are switched before and after swapping NICs, turn on the power of the target device again.

    For details, see the following manual:

    • PRIMEQUEST 2000 Series

      "PCI Card Hot Maintenance in Red Hat Enterprise Linux 7" in "PRIMEQUEST 2000 Series Administration Manual"

  9. Perform post-swap processing.

    1) Activate the interface of the swapped NIC.

    # /sbin/ifup ethX

    2) Restore the NIC (interface name: ethX) that was temporarily deleted prior to swapping in 1) of step 1.

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

    3) Enter the dsphanet command to confirm that the device status of the swapped NIC (interface name: ethX) is "OFF".

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

    4) If necessary, fail-back the NIC.

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

    5) Restart network monitoring.

    # /opt/FJSVhanet/usr/sbin/hanetpathmon on

For GS linkage mode

  1. Prepare for swapping a card.

    1) From the virtual interface definition, temporarily delete the definition information about the NIC to be swapped (The interface name of the target NIC is ethX).

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

    2) Enter the dsphanet command to confirm that the device status of the target NIC (interface name: ethX) is "CUT".

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

    3) Deactivate the interface of the target 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 device.

    The interface (ethX) is deleted when power is turned off.
