VMware Recertification Policy

March 10, 2014March 6, 2017 VMware

Starting today, March 10 2014, new VCP certifications must be re-certified within two years of it’s earned date. Anyone who currently has their VCP certification prior to March 10 2013 has until March 10, 2015 to re-certify.

The new policy gives you three options to re-certify:

Take the current exam for your existing VCP certification solution track. For example, if you are a VCP3, you could take the current VCP5-Data Center Virtualization (VCP5-DCV) exam.
Earn a new VCP certification in a different solution track. For example, if you are a VCP-Cloud, you could recertify by earning VCP5-Desktop (VCP5-DT) certification.
Advance to the next level by earning a VMware Certified Advanced Professional (VCAP) certification. For example, if you are a VCP5-DCV you could earn VCAP5-DCA certification.

I can understand why they are doing this but I don’t agree with the changes. As per the announcement if you let your certification expire, “Your certification will be revoked,and you will no longer be entitled to use the certification logo or represent yourself as VMware certified“. Really? You mean everything that was done prior and after taking the exam means nothing?

How to use Site Recovery Manager DR IP Customizer

As one of the tasks given to me include protecting critical virtual machines via Site Recovery Manager (SRM) I ran into an environment that needed to be protected and have static IP’s assigned to them. The environment consists of about 15 VM’s, all of the VM’s each have 5 NIC’s with two of the VM’s having 9 NIC’s – that’s a lot of NIC’s to manually configure on both the Protected and Recovery side in SRM.

Looking through the SRM Documentation I was able to see that VMware has graced us with a wonderful tool to greatly speed up this process, dr-ip-customizer.exe!

Upgrade ESXi host to ESXi 5.5 using VMware Update Manager 5.5

January 10, 2014March 6, 2017 VMware

A while back I wrote about how to upgrade to ESXi 5.5 via command line which works great when you only have a few hosts as each host has to download the ISO from the web each time. This time I’ll show you step by step how to upgrade your ESXi 5.1 host to ESXi 5.5 using VMware Update Manager 5.5 (aka VUM).

For this post I’m going to assume you have already upgraded your vCenter and VUM to versions 5.5 as well as the VUM plugin installed. So lets begin!

Upgrade ESXi host to 5.5 using VMware Update Manager (VUM)

Open the vSphere client and click on Update Manager

VMware hasn’t let the holidays get in their way and has released vCenter Server 5.5b (Build 1476387) along with vCenter Server Appliance 5.5.0b (Build 1476389). The update includes a number of fixes.

Resolved Issues in 5.5.0b

Attempts to upgrade the vSphere Web Client to vSphere 5.5 fails when they are installed in a custom, non-default location. An error message similar to the following is displayed:

Restore a VM using the {vm}-flat.vmdk file

December 15, 2013January 13, 2015 VMware

A couple days ago I was asked the question “An admin deleted the vmdk file associated with a VM, there are no snapshots or backups of the VM . Can we restore this VM somehow?“. I believe in backups, I like to have my VM’s backed up so that I can depend on them for events just like this very issue. At first I was stumped, until the {vm-name}.flat.vmdk was mentioned. That’s when I remembered a method to recover a VM using the vm-flat.vmdk file that I had actually done 2-3 years ago.

Set default printer for View floating desktop and Persona Management

December 11, 2013 VMware

5 Comments

Sometime ago I asked a question over at the VMware forum about how to set default network printers on a VMware View 5.0 floating pool that used Persona Management as Persona Management wasn’t keeping this user setting on it’s own. The printers would be added to the VM just not remember the default printer setting. I’ll admit I forgot to update the thread, but a work around was devised which I’ll share below.

Increase incremental backup speed by enabling CBT

November 26, 2013November 4, 2014 VMware

2 Comments

In a recent VMware environment I was working in, we noticed that our incremental backups was taking a long time (like up to 7-8 hours) to complete. After digging around it was found that VMware actually has a feature built-in since version 4 called Change Block Tracking (CBT). CBT will track any blocks that were changed since the last backup and tag them and stores the information in a -CTK file. The obvious benefit is that now the third party software only backs up the changed block and not the entire VM each time, reducing the amount of data being backed thus speeding up backups and even lowers the CPU utilization on the VM host.

CBT is disabled by default though there are some backup tools that will enable it automatically or you can enable it manually which can easily be done following these steps:

VMware 5.3 View available

VMware Horizon View 5.3 is now generally available (GA) for download. View 5.3 brings a number of cool features and if you haven’t heard about them yet be sure to check out my VMware Horizon View 5.3 announcement post. Lots of improvements for such a tiny version number change!

Shrink a thin provisioned VMDK disk

November 7, 2013November 3, 2013 VMware

When maintaining a Horizon View environment I like to keep my parent images as small as possible and over time a thin provision disk can start to grow on you if you don’t watch it – be it from downloading installers, updates, or even running disk defrag. While there isn’t a simple, one click button in the View Administrator Console there is a fairly easy manual method using vmfkstools.

Before we can use “vmkfstools” to shrink the VMDK file we must zero out any unused space on the thin provisioned disk. A simple way of doing this is by using a free utility called SDelete from Sysinternals.

VMware vCenter Server 5.5.0a update released

November 4, 2013November 18, 2013 VMware

0 Comments

VMware has released an update to vCenter 5.5 Server. The new updated, numbered 5.5.0a doesn’t appear to add any new features but instead focus on squishing a number of bugs in the 5.5 version – mostly around vCenter Single-Sign-On and the vSphere web client.

Issues resolved with this release are as follows:

Attempts to upgrade vCenter Single Sign-On (SSO) 5.1 Update 1 to version 5.5 might fail with error code 1603
Attempts to log in to the vCenter Server might be unsuccessful after you upgrade from vCenter Server 5.1 to 5.5
Unable to change the vCenter SSO administrator password on Windows in the vSphere Web Client after you upgrade to vCenter Server 5.5 or VCSA 5.5
VPXD service might fail due to MS SQL database deadlock for the issues with VPXD queries that run on VPX_EVENT and VPX_EVENT_ARG tables
