JET install: ERROR: Unable to configure network interface Exiting to shell

Question

Using SUNWjet v4.4.4 I'm trying to build a server using update 5 x86 which seems
to work with one notable exception. The JET server and the build server do not
reside on the same subnet. In order to get around not being able use PXE boot
to boot the build server I'm booting from DVD after making the following modifications
to the grub menu entry:
kernel /I86PC.Solaris_10-1/multiboot kernel/unix - install nowin -B
install_config=x.x.x.x:/opt/SUNWjet,
sysid_config=x.x.x.x:/opt/SUNWjet/Clients/testclient,
install_media=x.x.x.x:/export/install/media/s10u5-x86,
install_boot=x.x.x.x:/export/install/media/s10u5-x86/boot
This seems to kick off the installer however it fails to bring up the network interface:
SunOS release
Configuring devices
Solaris Interactive Text ( Console Session )
ERROR: Unable to configure network interface Exiting to shell
# ifconfig bge0 x.x.x.x up netmask 255.255.255.0
# route add default x.x.x.1
# exit
Using RPC
Installation continues without any errors
It seems that I'm forced to bring up the interface manually each time.
This is what the template looks like:
base_config_ClientArch=i86pc
base_config_ClientEther=XX:XX:XX:XX:XX:XX
base_config_ClientOS=s10u5-x86
base_config_client_allocation="grub"
base_config_products="custom eiscd sds"
base_config_sysidcfg_nameservice=NONE
base_config_sysidcfg_network_interface=PRIMARY
base_config_sysidcfg_ip_address=x.x.x.x
base_config_sysidcfg_netmask=255.255.255.0
base_config_sysidcfg_root_password="XXXXXXXXXXXX"
base_config_sysidcfg_system_locale="en_CA.UTF-8"
base_config_sysidcfg_timeserver=
base_config_sysidcfg_timezone="Canada/Eastern"
base_config_sysidcfg_terminal=vt100
base_config_sysidcfg_security_policy=NONE
base_config_sysidcfg_protocol_ipv6=no
base_config_sysidcfg_default_route=x.x.x.1
I've also tried setting the following:
base_config_sysidcfg_network_interface=PRIMARY
vs
base_config_sysidcfg_network_interface=bge0
I don't mind doing this manually but of course I would much rather have it work automatically.

Answer 1

Try giving more network interface settings in the sysidcfg settings:
network_interface=value {primary hostname=host_name
                          default_route=ip_address or NONE
                          ip_address=ip_address
                          netmask=netmask
                          protocol_ipv6=yes_or_no}
