Perform this settings only in RHEL7.
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.
Confirmation method
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
HOTPLUG=no |
