Sample script for automating the installation of ESXi 4.1 on Cisco UCS with UDA

Thanks to Mike Laverick the Ultimate Deployment Appliance now supports ESXi 4.1. –

I developed a script for automating the installation of ESXi 4.1 on Cisco UCS boot from SAN. The UDA template I setup uses a subtemplate for the host names, management IP and vMotion IP.

Here is my configuration:

  1. 6 GB Boot LUN hosted on an EMC CX4
  2. Cisco UCS B200-M1 blades
  3. Cisco VIC (Palo) adapters
  4. These vNICs


And these vHBAs



Here is the subtemplate I am using


Here is the script I am using

rootpw –iscrypted $1$NvqID7HA$mkw26HiBQgbso6jk1jX014
clearpart –alldrives –overwritevmfs
autopart –firstdisk=fnic –overwritevmfs
install url
network –bootproto=static –ip=[IPADDR] –gateway= –nameserver= –netmask= –hostname=[HOSTNAME] –addvmportgroup=0

%firstboot –unsupported –interpreter=busybox

#Set DNS
vim-cmd hostsvc/net/dns_set –ip-addresses=,

#Add pNIC vmnic1 to vSwitch0
esxcfg-vswitch -L vmnic1 vSwitch0

#Add new vSwitch for vMotion
esxcfg-vswitch -a vSwitch1

#Add vMotion Portgroup to vSwitch1
esxcfg-vswitch -A vMotion vSwitch1

#Add pNIC vmnic2 to vSwitch1
esxcfg-vswitch -L vmnic2 vSwitch1

#Add pNIC vmnic3 to vSwitch1
esxcfg-vswitch -L vmnic3 vSwitch1

#Assign ip address to vMotion vmk1
esxcfg-vmknic -a -i [VMOTIONIP] -n -p vMotion

#Assign VLAN to vMotion PortGroup
esxcfg-vswitch -v 12 -p vMotion vSwitch1

#Enable CDP listen and advertise
esxcfg-vswitch -B both vSwitch0
esxcfg-vswitch -B both vSwitch1

sleep 5

#Enable vMotion to vmk1
vim-cmd hostsvc/vmotion/vnic_set vmk1

#Set NIC order policy for vMotion port groups
vim-cmd hostsvc/net/vswitch_setpolicy –nicorderpolicy-active=vmnic3 –nicorderpolicy-standby=vmnic2 vSwitch1

#enable TechSupportModes
vim-cmd hostsvc/enable_remote_tsm
vim-cmd hostsvc/start_remote_tsm
vim-cmd hostsvc/enable_local_tsm
vim-cmd hostsvc/start_local_tsm
vim-cmd hostsvc/net/refresh

# NTP time config
echo restrict default kod nomodify notrap noquerynopeer > /etc/ntp.conf
echo restrict >> /etc/ntp.conf
echo server >> /etc/ntp.conf
echo server >> /etc/ntp.conf
echo driftfile /var/lib/ntp/drift >> /etc/ntp.conf
/sbin/chkconfig –-level 345 ntpd on
/etc/init.d/ntpd stop
/etc/init.d/ntpd start

#One final reboot

The four additional vNICs will be used as uplinks to the Cisco Nexus 1000v dvSwitch.

  1. Jeremy, do you have to worry about the install wiping out any shared storage like the guide warns about? If so, do you have any method for making sure that doesn’t happen other than removing any mappings in the fibre switch?

  2. Yes, works great with ESXi 4.1. All of the esxfg- and vim-cmd commands work on ESXi if you SSH to it or login to the console.

  3. did you have any trouble with Cisco VIC drivers? (just wondering if UDA was able to see Network and HBAs for booting from SAN)
