VMware vSphere PowerCLI version 4.1 Update 1 released

VMware has released PowerCLI 4.1 Update 1 build 332441. This release of vSphere PowerCLI 4.1 Update 1 introduces the following new capabilities:

    * Using the ESX CLI and ESX Top features of VMware vSphere. (experimental)
    * Working with distributed switches and distributed switch port groups.
    * Supporting SCSI controllers.
    * Querying and modifying vCenter Server alarms.
    * Managing advanced vCenter Server settings and Cluster HA advanced options.
    * Waiting for VMware Tools of the specified virtual machines to load.
    * Querying information about disk and disk partitions of hosts.
    * Formatting host disk partitions.
    * Querying the primary HA cluster nodes.
    * Zeroing out virtual machine hard disks.

In addition, the following changes were made in PowerCLI 4.1 Update 1:

    * The DeleteFromDisk parameter of the Remove-VM, Remove-Folder, Remove-HardDisk, Remove-Template, and Remove-VApp cmdlets is now renamed to DeletePermanently.
    * The Set-VMGuestRoute cmdlet was removed for usability and stability reasons. Instead of modifying a route, you can create a new route and delete the old one.

The complete PowerCLI changelog can be found here and can be downloaded from this link.

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 listing of the 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.
