%post

cat << \EOF > /etc/rc3.d/S99postconfig.sh

#!/bin/sh

1. Change the amount of RAM allocated to the Service Console

cp /etc/vmware/esx.conf /etc/vmware/esx.conf.ORIG

perl -spi -e 's|/boot/memSize = \"272\"|/boot/memSize = \"800\"|' /etc/vmware/esx.conf

cp /etc/grub.conf /etc/grub.conf.ORIG

esxcfg-boot -g

esxcfg-boot -b

1. Unlink the default Virtual Switches created during install

2. since it was created with < 64 virtual ports:

/usr/sbin/esxcfg-vswitch -U vmnic0 vSwitch0

/usr/sbin/esxcfg-vswif -d vswif0

/usr/sbin/esxcfg-vswitch -d vSwitch0

1. Create the vSwitch0 vSwitch and the Service Console port group

/usr/sbin/esxcfg-vswitch -a vSwitch0:64

/usr/sbin/esxcfg-vswitch -A 'Service Console' vSwitch0

/usr/sbin/esxcfg-vswitch -M vmnic0 vSwitch0 -p "Service Console"

/usr/sbin/esxcfg-vswitch -L vmnic0 vSwitch0

1. Create the vSwitch1 vSwitch and the VMotion port group

/usr/sbin/esxcfg-vswitch -a vSwitch1:64

/usr/sbin/esxcfg-vswitch -A "VMotion" vSwitch1

/usr/sbin/esxcfg-vswitch -M vmnic1 vSwitch1 -p "VMotion"

/usr/sbin/esxcfg-vswitch -L vmnic1 vSwitch1

1. Create the vSwitch2 vSwitch for VM traffic

/usr/sbin/esxcfg-vswitch -a vSwitch2:64

/usr/sbin/esxcfg-vswitch -A "Virtural Maching Network" vSwitch2

/usr/sbin/esxcfg-vswitch -M vmnic2 vSwitch2 -p "Virtural Maching Network"

/usr/sbin/esxcfg-vswitch -M vmnic3 vSwitch2 -p "Virtural Maching Network"

/usr/sbin/esxcfg-vswitch -L vmnic2 vSwitch2

/usr/sbin/esxcfg-vswitch -L vmnic3 vSwitch2

1. Assign IP addresses to the Service Console interface and save it permanently:

/usr/sbin/esxcfg-vswif -a -i 192.168.2.57 -n 255.255.248.0 -p 'Service Console' vswif0

1. /sbin/route add default gw ESX_GATEWAY

1. Assign an IP addresses to the VMotion interface and add a VMkernel default route:

/usr/sbin/esxcfg-vmknic -a -i 192.168.0.132 -n 255.255.248.0 VMotion

1. /usr/sbin/esxcfg-route -a default VMOTION_GATEWAY

1. Enable VMotion on the VMKernel Interface ( this only works on ESX 3.5 )

2. vimsh -n -e "/hostsvc/vmotion/vnic_set vmk0" #not working#

1. Reset system to normal boot mode

echo "Seting System to normal boot up mode"

rm /etc/rc3.d/S99postconfig.sh

EOF

So I take this file and add it to a floppy called ks.cfg - boot off of the CD and point the install to esx ks=floppy and let it rip. Everything runs fine and when I get back to the server everything is installed. However from some reason nothing in the %post script runs. Non of my vswitch configs work.

When I nav to /etc/rc3.d/S99postconfig.sh I can see all of the commands but nothing has run. I'm new to Linux and scripting so I'm sorry if this is a stupid question.

Thank you for your help
