Good to see the blacklist=lpfc

We always disconnected Fibre Channel after a kickstart disk on the test system reformatted part of the SAN :(

The entry netwait=60 is a leftover from RHEL 5 but it hasn’t caused any problems with our RHEL 6 builds.  This entry just give the network device 60 seconds to enable before it tried to start networking.

We use blacklist=lpfc to make sure that the OS does not try to install on anything other than local devices.

 

Good luck,

You can set the IP address from the boot line.  You may need to know the mac address of the install interface if there is more than one interface on the server.

Hello,

I have following scenario:

- need to install very large number of physical servers

- RHEL repository is on the network filer (url install, NFS install available)

- there is no DHCP available (and it is not possible to have one - long story)
- I know serial number and IP for each server

My idea was to boot from installation image rhel-server-6.5-x86_64-boot.iso where I modified following:

- isolinux.cfg to load kickstart file

label Project
  menu label Project
  menu default
  kernel vmlinuz
  append ks=cdrom:/isolinux/ks.cfg initrd=initrd.img

add kickstart file containing network configuration in %pre script (get serial number from dmidecode, assign IP, install from network.  + configure hw raid etc etc)

Basically, something like this:


install
url --url 1.2.3.4.7/rhel-x86_64-server-6.5
...

%include /tmp/network


%pre
#!/bin/sh
#------------------------------------------------------------------------------#
#                     PRE-INSTALL NETWORK SETUP        #
#------------------------------------------------------------------------------#

echo "network --bootproto=static --vlanid=123 --ip=1.2.3.4 --netmask=255.255.248.0 --gateway=1.2.3.5 --nameserver=1.2.3.6 --device=eth0" > /tmp/network

 

But. System asks for network settings when booted.
I understand that I need to have stage2 loaded before anaconda starts %pre section. So, I need it to use stage2 from iso. But it looks for stage2 on the network when there is url as source in kickstart file. Is there any way how to tell installer:

- start Anaconda from CD (use local install.img), run %pre, download packages from url ?

file copied to /tmp/ks.cfg

setting up kickstart

kickstart forcing text mode

trying to mount CD device /dev/sr0 on /mnt/stage2

Do you have any idea if it possible to somehow change this stage2 behavior? I found Anaconda boot options but I am unable to set stage2 either by stage2= or inst.stage2=. 

(Any other idea how to set IP in ks.cfg and use it for packages downloading without DHCP would be also appreciated.)
