Hi all,
I'm sending an extension of the existing linuxrc.s390 -- the script
implementing the initial installation dialog for RHEL on System z.
INTRODUCTION
After booting the installation environment on System z, there are no
local storage devices such as a CD/DVD drive available to install RHEL
from. Hence, only installation from network sources is possible, which
requires an initial setup of a network device to reach such an
installation source.
Due to the possibly large number of hardware network devices
(hundreds) and the way they are configured in the hardware setup,
Linux does not automatically detect and allocate all available network
devices. There is need for a dialog from which the user can choose a
sensible device configuration.
The least common multiple of console devices on System z is limited in
functionality -- it only supports line mode. The initial network setup
also provides the ability for users to login over the network from a
curses capable text terminal, to provide an X window display, or to
use VNC in order to continue installation.
DOWNSIDES OF CURRENT LINUXRC.S390
The initial network setup was done with a simple error-prone dialog
without any possibility for the user to correct wrong input. On
getting stuck, the only option for the user was a reboot, which of
course means that he had to manually enter values all over again.
The user was asked various questions and had to know exactly what
answers to provide for a successful network setup. Linuxrc.s390
provided no guidance or support to simplify the choice of correct
answers for the user.
Configuration happened after the user had answered all questions which
could lead to situations where configuration failed due to an earlier
incorrect answer the user was not informed about.
User feedback has shown, that these downsides can be an obstacle for a
successful installation of RHEL on System z.
IMPROVEMENTS OF NEW LINUXRC.S390
- dialog allows the user to correct single answers
- dialog allows to restart configuration,
providing previous answers as default values
- dialog provides a sub shell for problem determination
- cut-down question text prevents frequent scrolling on line mode
terminal
- explaining help text is shown for each question on user demand
- automated decision which questions the user has to answer
- semi-automatic configuration of network devices by providing
a selection list of possible hardware configurations
- manual configuration remains possible as before
- sensible default answers are provided where possible
- superfluous questions (NETWORK, BROADCAST) have been removed
- answers by the user are strictly checked for syntax and semantics
- whenever possible, each answer is used to do a configuration step
and provide timely feedback to the user in case of an error
- user transparent support of System z device blacklist (cio_ignore)
for short boot times on systems with many (thousands) devices
- basic support for installation from FCP-attached CD/DVD drive
(our version of linuxrc.s390 is based on rhel5.3-snap1-20081029)
- basic support for installation over IPv6
(full functionality would require further support in loader)
- prints answers in a format which can directly be used for parm/conf
file (as a complement to /root/anaconda-ks.cfg)
- may serve as a specification on how to configure network devices on
System z outside of an installer, e.g. in init scripts or
configuration tools such as system-config-network
Otherwise, our version is fully compatible with the current version
including the processing of parm/conf files. We made sure that
existing parm/conf files from users are processed with the same
outcome as previously. Also the interactive mode asks the user
questions in the same order as before, so users do not have to adapt
to a completely new structure of the initial network configuration.
TEST
The attached version of linuxrc.s390 and the helper script lsznet.raw
(called by linuxrc.s390 to enumerate sensible network hardware
configurations) have been tested within an installer initrd taken from
RHEL 5.2. Full installation cycles both without and with kickstart
mode have been performed. We considered different network hardware
(both real and virtual) and installed from sources accessible over
different protocols (FTP, HTTP, NFS).
ATTACHMENTS
- Two bash scripts implementing our improvements:
linuxrc.s390: initial installation dialog for RHEL on System z
(sorry, had to gzip it due to mailing list size limit)
lsznet.raw: list sensible network device hardware setups for Linux on
System z
- Console logs showing capabilities of the user interface by example:
guest2auto.txt : using auto detection, GuestLAN (QDIO) in layer 2 mode
=> does not ask for MAC address since it detected a virtual NIC.
osa2man.txt : manual configuration (e.g. by an expert knowing all
parameter values), OSA network device in layer 2 mode => does ask for
MAC address since it detected a real OSA, DNS servers could not be
reached by ping due to our network environment denying ICMP echo to
those hosts => user chose to continue anyway since he knows better.
lcsks.txt : unattended installation with parm & conf file and
kickstart file, LCS network device, succeeds without user interaction.
guest3err.txt : manual configuration with many intentional error
inputs, chose layer 2 mode on purpose even though GuestLAN (QDIO) was
configured as layer 3 => device cannot be set online => user restarts
whole configuration dialog to correct the previous wrong input for
layer mode, finally succeeds, using sub shell to verify that necessary
devices have been removed from blacklist so that the devices can
actually be used.
OUTLOOK
Feedback is welcome and I'm happy to answer any questions that may
arise.
Kind regards
