VMware ESX Post installation configuration via PowerCLI

I made a simple example script using the VMware PowerCLI that can be used to do the post installation configuration of a VMware ESX 4 server. This script does the following things:

  • Connect to VMware ESX server
  • Set the SC memory to 800MB
  • Creates vSwitch2 and add vmnic2 and vmnic3
  • Add several PortGroups and VLANs to vSwitch2
  • Remove default PortGroup VM Network
  • Creates a VMkernel VMotion port with IP address, subnetmask and VLAN
  • Add vmnic0 and vmnic1 to vSwitch0, set for the VMotion port vmnic1 active and vmnic0 standby and for the Service Console port vmnic0 active and vmnic1 standby
  • Configure NTP servers and open the firewall
  • Sets advanced settings Disk.UseDeviceReset to 0 and Disk.UseLUNReset  to 1
  • Sets he Qlogic HBA queue depth and the Disk.SchedNumReqOutstandig to 64
  • Enable VMhost Startup and stop

Here’s the PowerCLI script:

It’s easy to adjust the settings for your need. This shows the strength to use the PowerCLI for doing automation in VMware. If you have suggestions please let me know.
