Ignite postinstall help

Doug Van tol — Tue, 18 Jan 2000 12:55:06 GMT

Hello all,

I'm attempting to use Ignite to make 3 idententical systems, with the only
exception being the hostname and ip address. I tried having the post install
script update the /etc/rc.config.d/netconf file by querying the system name
from the user. The script creates a copy of the netconf file and then attempts
to copy it back over the original. I made sure I changed the permissions on
the file to allow write access. The new netconf file is generated, however, it
seems to get overwritten by the file contained in the archive. I have tried
changing the post load script in the netconf section to no avail. Any
suggestions would be greatly appreciated.

Thanks in advance,

Doug

Hi:

You have two posibilities:

1- Dont make anything. At instalation time select advanced install from first
menu.

On system tab you can configure hostname and ip address or select ask for them
after reboot.

2- Edit CONFIG file and set following parameters:

system_name="xxxxx"
ip_addr[]="xxx.x.xxx.xx"
netmask[]="255.255.255.0
route_gateway"xxx.x.xxx.xxx"
route_destination[0]="default"

Then make differents tapes for each server.
See instl_adm(4). instl_adm is a language so you can program to do just a tape.

I like first option because it is simple, but in real work I had used then
second.

Thanks Carlos,

I currently have the second method implemented. I am really looking for a way
to prompt the installer (customer) for the system name and then have the system
configure itself corrently based on the name. I was trying to implement this
method without the GUI interface. Now I'm not sure if that is possible.

Helo again:

I have instaled about 20 remote servers just telling to end users how to boot
from the DAT.

Previously i had send them a DAT and a CD.

CD was duplicated copies from Ignite cold instalation.

DAT was generated with the information for each server. DATs only contains Boot
system and a CONFIG file in it with, also generated by ignite make_medialif.

Before i Had copy with dd the LIF_VOLUME generate by iginte:

dd if=/dev/rmt/0m of=/tmp/LIF_DAT bs=2k

PARAMETER FILE ( server_xx):
_______________-

run_ui=false
control_from_server=false
disable_dhcp=true
server="xxx.xx.xx.xx"
# instl_adm defaults:
server="xxx.xx.xx.xx"
system_name="XXXXX"
ip_addr[]="xxx.x.xx.xx"
netmask[]="255.255.255.0"
route_gateway[0]="xxx.x.xx.xxx"
route_destination[0]="default"
sysadm_message = " You will install
System XXXX IP XXX.XX.XX.X
"

_______________
#Apply parameter file (Server_xx)
instl_adm -f Server_xx -F /tmp/LIF_DAT

dd if=/tmp/LIF_DAT of=/dev/rmt/0m bs=2k

Of course, some parameter from CONFIG were changed to set CD as software
source.

It take a some work but , you ( and Ignite) can do it.

Regards.

We use ignite to create clients for 10.10, 10.20, 11.00. Workstations, and have
the same need you do.
here are the steps that we follow:
1. - Create the desired image "golden image" as hp calls it, by going to the
"model" workstation and running 'make_sys_image' [man page avail.] (You will
need to trust the root client to the server - mod the /.rhosts file on the
server)
2. Once it is created, put it on a partition that is exported [/etc/exports]
and nfs available.
3. On the ignite server - edit the file /var/opt/ignite/INDEX to point to a
config file.
4. Edit the config file - there are examples if you follow a set up config file
from the orginal INDEX.
A sample of a config file that can be used with a core
archive can be found at:
/opt/ignite/data/examples/core.cfg
5. Run Ignite from the server and set the workstation up. If the clients are
on a separate subnet, then you will need to set up
6. Just ignite the workstation. I think I have detailed instructions around,
but the man pages are pretty good. Each system takes 40 minutes to load a 4Mb
OS (roughly ex-B180)
