Another mechanism that allows you to dynamically ignore disks (so you
don't have to explicitly list them in each kickstart file) would be:
%pre
echo "bootloader --location=mbr --driveorder=cciss/c0d0" >
/tmp/bootloader
IGNOREDISK=/tmp/ignoredisk
### Ignore qlogic disks for PHYSICAL systems
cat /tmp/scsidisks
echo "Pulling in contents of /tmp/scsidisks"
for i in $(cat /tmp/scsidisks | awk '{ print $1 }'); do
DISKS=$DISKS" "$i
done
echo $DISKS
echo "Pulling in all block device sd* files in /tmp"
for i in $(ls -l /tmp | grep sd | grep ^brw | awk '{ print $NF }');
do
DISKS=$DISKS" "$i
done
echo $DISKS
DISKS=$(echo $DISKS|sed 's/ s/,s/g')
if [ ! -z $DISKS ]; then
echo "ignoredisk --drives="$DISKS > $IGNOREDISK
else
echo ""> $IGNOREDISK
fi
Then in the main section of the ks.cfg just:
%include /tmp/bootloader
%include /tmp/ignoredisk
For HP systems (with SmartArray controllers at least), the cciss/c#d#
devices do not show up in /tmp/scsidisks.
Also, this does work with both RHEL4 and RHEL5 very successfully. Since
we generate individual kickstart files off of the same template for both
SAN and non-SAN system, the above script works nicely.

Thanks - that might work, too.

I got this from a Red Hat Global Professional Services consultant
(cheers Dean, if you're reading this). I've just extracted it from a
satellite kickstart profile for a RHEL5 box we have - I suppose it might
work with RHEL4 too.
Put the following %pre script block in your kickstart file to prevent
the listed drives from being used by fdisk/lvm/mkefs:
%pre
cat <<EOF > /tmp/partitioning
ignoredisk
--drives=sda,sdb,sdc,sdd,sde,sdf,sdg,sdh,sdi,sdj,sdk,sdl,sdm,sdn,sdo,sdp
,sdq,sdr,sds,sdt,sdu,sdv,sdw,sdx
key 49af89414d147589
EOF
In your partitioning section, include the file that you create in the
pre script by adding this line
%include /tmp/partitioning
And then correct for the drive-ordering that might mean that your
HBA-accessible drives come before your local storage. In this case, I
wanted the local HP smartarray disk to come before all the HBA disks.
Use the following line:
bootloader --location mbr --driveorder
cciss/c0d0,sda,sdb,sdc,sdd,sde,sdf,sdg,sdh,sdi,sdj,sdk,sdl,sdm,sdn,sdo,s
dp,sdq,sdr,sds,sdt,sdu,sdv,sdw,sdx
N.B. I have no idea what the "key 49af89414d147589" does in the pre
script - I've never noticed it before today. Anyone?
Regards,
Nik
