This section describes the procedure for swapping a NIC whose virtual interface makes it redundant.
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 |
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] Name Status Mode CL Device +----------+--------+----+----+------------------------------------------------+ shaX Active t OFF ethX(CUT),ethY(ON) |
3) Deactivate the NIC.
|
# /sbin/ifdown ethX |
The interface (ethX) is deleted when power is turned off. For details, see "B.2.3.2 Power-on and power-off procedures" of the "PRIMEQUEST 480/440 Operation Manual".
|
# echo 0 > /sys/bus/pci/slots/"<slot-number>"/power |
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 |
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).
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 |
2) Activate the swapped NIC.
|
# /sbin/ifup ethX |
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) |
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 |
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] 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] 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 NIC.
|
# /sbin/ifdown ethX |
The interface (ethX) is deleted when power is turned off. For details, see "B.2.3.2 Power-on and power-off procedures" of the "PRIMEQUEST 480/440 Operation Manual".
|
# echo 0 > /sys/bus/pci/slots/"<slot-number>"/power |
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 |
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).
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 5.
ifcfg-ethX (NIC that was swapped)
|
DEVICE=ethX |
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) 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.
# /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 |
4) If necessary, fail-back the NIC.
|
# /opt/FJSVhanet/usr/sbin/hanetnic change -n shaX |
5) Start standby patrol monitoring. If the standby patrol function is not used, skip this step.
|
# /opt/FJSVhanet/usr/sbin/strptl -n shaY |
6) Restart hub monitoring.
|
# /opt/FJSVhanet/usr/sbin/hanetpoll on |
7) Restart interface status monitoring.
|
# /bin/rm /var/opt/FJSVhanet/tmp/disable_watchif |
