RHEL Kickstart pre-install script

[RUSHE John (AXA-TECH-UK)]

I am trying to come up with a standard kickstart script for installing
RHEL on all our (differing) servers.

We have a mixture of kit, some with ide and some with scsi disks. In my
%pre script, I can manage to determine how many ide or scsi disks there
are in the system but I cannot find anyway to determine which device
names have been allocated. Here is my script, so far....

#!/bin/sh

#set -x
num_scsi=0
num_ide=0

exec 3<&0                                       # save the current
location of stdin
exec 0< /proc/scsi/scsi                         # reassign latest
kickstart to stdin
while read Type SCSI DROSS                      # read contents of
/proc/scsi/scsi
do
   case $Type in
    Type:)
       if [ "${SCSI}" = "Direct-Access" ];
       then
          num_scsi=`expr $num_scsi + 1`
          echo "Found SCSI Direct Access Device"
       fi
       ;;
   esac
done

echo "Found ${num_scsi} scsi disks..."

# Determine number of IDE disks (if any)

hds=""
media=""

for file in /proc/ide/h*
do
  media=`cat $file/media`
  if [ $media == "disk" ];
then
     hds="$hds `basename $file`"
  fi
done


What I am trying to do is to get the kickstart to semi-intelligently
auto-generate the partition information. For IDE this is pretty straight
forward since two IDE disks *usually* equates to /dev/hda and /dev/hdb.
Scsi is a little different in that hardware raid can confuse the issue
(we have a COMPAQ ML370 for example and the disks appear as
/dev/cissp/c0d0 etc). Is there anything during the kickstart install
which will enable me to capture (within the pre-install script) the
device names for the disk drives so that I can then generate the
kickstart partitioning on the fly based on which physical disks are
installed on the machine? I have tried trawling through /proc but so far
no success...

Cheers

John
