Check that the NICs used by GLS have been set to disable the operating system's hotplug function. The hotplug function is a Linux function that automates the assignment of IP addresses when interfaces are created. When GLS is used, GLS itself manages IP addresses. Therefore, you need to disable this function. Also, if you do not make this setting, the activation and deactivation of interfaces by GLS may fail. For details, see "3.2.2.1 Setup common to modes". Note that, for RHEL5, you need to add settings in the /etc/udev/rules.d/60-net.rules file as well as in ifcfg-ethX.
Confirmation method
In RHEL5 and RHEL6, check that the HOTPLUG=no setting has been made for /etc/sysconfig/network-scripts/ifcfg-ethX.
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=10.33.88.170
NETMASK=255.255.255.0
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no |
In RHEL5, in addition to the setting of HOTPLUG=no, check that the hotplug function is set to be disabled for the device name "sha" in /etc/udev/rules.d/60-net.rules.
# cat /etc/udev/rules.d/60-net.rules SUBSYSTEM=="net", ENV{INTERFACE}=="sha*", GOTO="skipgls" ACTION=="add", SUBSYSTEM=="net", IMPORT{program}="/lib/udev/rename_device" SUBSYSTEM=="net", RUN+="/etc/sysconfig/network-scripts/net.hotplug" LABEL="skipgls" |
