Issue

Check Active IQ if this impacts your systems.

The network interfaces from the rc file as well as the hostname need to be present in the hosts file in order to assign an IP address. If all interfaces are not defined, an outage can occur after a takeover / giveback or on reboot.

Example:
/etc/rc  file:

hostname filer
ifconfig e0a `hostname`-e0a netmask 255.255.255.0 partner e0a mtusize 1500

ifconfig e0b `hostname`-e0b netmask 255.255.255.0 partner e0b mtusize 1500

/etc/hosts file:
127.0.10.1 localhost-10 localhost-bsd
127.0.20.1 localhost-20 localhost-sk
10.10.10.10 filer filer-e0a
