netmasksWarning Displayed When Booting Zone

If you see the following message when you boot the zone as described in How to Boot a Zone:

# zoneadm -z my-zone boot
zoneadm: zone 'my-zone': WARNING: hme0:1: no matching subnet
	found in netmasks(4) for 192.168.0.1; using default of
	255.255.255.0.

The message is only a warning, and the command has succeeded. The message indicates that the system was unable to find the netmask to be used for the IP address specified in the zone's configuration.

To stop the warning from displaying on subsequent reboots, ensure that the correct netmasks databases are listed in the /etc/nsswitch.conf file in the global zone and that at least one of these databases contains the subnet and netmasks to be used for the zone my-zone.

For example, if the /etc/inet/netmasks file and the local NIS database are used for resolving netmasks in the global zone, the appropriate entry in /etc/nsswitch.conf is as follows:

netmasks: files nis

The subnet and corresponding netmask information for the zone my-zone can then be added to /etc/inet/netmasks for subsequent use.

For more information about the netmasks command, see the netmasks(4) man page.
