When I was playing with ESXi 5.0 in my lab I noticed some changes during the installation process. Of course I had not bothered to read the documentation but when I watched the installer fail I figured it might make sense to start reading. I’ve documented the scripted installation procedure multiple times by now. But in short, when you would boot using the ESXi CD-ROM you would simply need to edit the following string and make it look as follows:

With ESXi 5.0 this has been simplified, this is what it looks like today:

I also want to point out that many of the standard installation commands have been replaced, removed or are not supported anymore. I created a simple script to automatically install an ESXi 5.0 host. It creates a second vSwitch and a second VMkernel for vMotion. It enables both the local and remote TSM and sets the default PSP for the EMC VMAX to Round Robin. As you can see there is a huge shift in this script towards esxcli. Although some of the old “esxcfg-*” commands might still be working they are deprecated and no longer supported. The new standard is esxcli, make sure you get familiarized with it and start using it today as over time this will be the only CLI tool available.


# Sample scripted installation file
# Accept the VMware End User License Agreement
vmaccepteula
# Set the root password for the DCUI and ESXi Shell
rootpw mypassword
# Install on the first local disk available on machine
install --firstdisk --overwritevmfs
# Set the network to DHCP on the first network adapater, use the specified hostname and do not create a portgroup for the VMs
network --bootproto=dhcp --device=vmnic0 --addvmportgroup=0
# reboots the host after the scripted installation is completed
reboot

 

%firstboot --interpreter=busybox
# Add an extra nic to vSwitch0 (vmnic2)

#Assign an IP-Address to the first VMkernel, this will be used for management
esxcli network ip interface ipv4 set --interface-name=vmk0 --ipv4=192.168.1.41 --netmask=255.255.255.0 --type=static
# Add vMotion Portgroup to vSwitch0, assign it VLAN ID 5 and create a VMkernel interface
