How to Set Up a 9.0x System as a Boot Helper
Essentially, the 9.05 helper machine, on the same subnet as the install
target machine(s), hosts the files necessary for network boot of the
target. Once the target has booted, it can run the remainder of the
installation across a gateway. The boot files, in addition to providing the
installation kernel and program, also direct the target to the proper
server machine on the other side of the gateway.
There are two major steps that need to be done: the 9.0X helper machine
has to be modified somewhat to host the 10.X install files, and the boot
files have to be modified on the 10.X install server and copied over to the
9.0X helper. It is not possible to copy the boot files to the helper first and
modify them under 9.0X.
On the (9.0X) helper, do the following:
1. mkdir -p /opt/ignite/boot
2. Edit /etc/inetd.conf: 1. Add the following line
/opt/ignite
to the tftp spec. Don’t forget to add \ to the line before it for
continuation.
2. Modify the instl_boots spec to be the following (add the -b
option):
instl_boots dgram udp wait root /etc/instl_bootd instl_bootd -b\
/opt/ignite/boot/boot_lif
3. Run /etc/inetd -c to reread the config.
4. Make sure /usr/adm/instl_boottab on the helper has some booting IP
addresses available/specified.
5. After the install server steps below are finished, you will copy over the
install boot-up files from the server to /opt/ignite/boot. These files
will direct the target machine to the install server (across the gateway)
for the remainder of the install.
