VMware Configurations Maximum Tool URL

VMware has created a nice friendly URL - https://configmax.vmware.com to help you quickly look at the configuration maximums across a few of their product ; NSX Data Center for vSphere, vSphere, VMware NSX-T, vRealize Operations Manager and VMware Site Recovery Manager. I assume VMware will add more as time goes by. As you can see from the screenshot I have selected vSphere as the product and the version is 6.7 . Under All Maximum  you can select which maximums you want to view. From my screenshot I have selected Virtual Machine Maximums  and to the right of the screen you can see all the maximum related to virtual machines. You can select to display other maximums as well and click View Limits  to have the data updated, use the collapse all button to help collapse all the section of  your selected configuration maximums . There is a button to export all maximums to pdf     which exports all the maximums and not just what you have filtered down for display on the screen. It

vCenter Server Appliance root expiry changed from 365 to 90 days

When you deploy a new vSphere 6.7 vCenter Server Appliance the root password validity period by default is now 90 days.  This has changed from vSphere 6.5 which was at 365 days.  If you was doing an upgrade then the settings you have configured are carried over. Just remember that for new deployments the root password validation has changed from 365 to 90 days.  There is no change to vSphere single sign on which is still set at 90 days.

Disabling Server Manager from startup at logon

One of the first things I do when I first logon to a 2016 server is always to disable server manager from loading at logon. Reason for me? annoying and not a tool I always need each time I log on to a server. There are a couple of places you can disable this feature and I will walk through a few To disable it for your current logged in user you would go to Manage > Server Manager Properties Tick box Do not start Server Manager automatically at logon  and click OK and this setting will apply for the currently logged in user. Another GUI method would be to use group policy to apply the settings for all users that use the computer. On a workgroup server at the command prompt or at the run command type in gpedit.msc . This will load up the group policy editor for the server you are logged into. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > System > Server Manager . Here you will find the setting Do not display Server M

Running ESXi 6.7 on Ravello

As with my previous article I talked about deploying ESXi 6.0/6.5 onto the Ravello platform and it was pretty straight forward as you are provided with  a base template of an ESXi which you just add to your application canvas, attach the ISO and off you go. With 6.7 on the Ravello platform you will most likely experience this Purple Screen Of Death if you try to just use the ESXi template. After many googling and looking around forums there was a solution !! Now there are some caveats that I found if you wish to deploy ESXi 6.7 to one of your existing applications. If your application is not published to "US East 5" or US Southwest 1" then the method below will not work. You will need to create a new application to host your ESXi 6.7 host. It appears that only hardware that are hosted in "US East 5" and US Southwest 1" supports running ESXi 6.7. So as with my previous article you would still use the ESXi template but we will make some modification

Running VMware on Ravello

One of the many benefits of being a vExpert is the freebies that you get from vendors. Ravello from Oracle is one of them where you are able to run your VMs on their hypervisor in the public cloud space. One of the selling points is that you can just copy your vmdk files up to the system and you don't need to reconfigure your VM hardware and settings to get it running. The platform also allow you to run a hypervisor such as ESXi as a VM which means I can have a lab on the move in the cloud. With all freebies there are some gotcha which is I only get 1000 CPU hours per month and can run only 20 concurrent VMs but as its for a lab/testing this is more than enough. In this article I will run through the steps to just get a ESXi 6 host up and running on their platform and if you want to try it they offer free trial  here So once you signed up you head over to https://cloud.ravellosystems.com  to login to the management portal Once you are logged in we would need to go to Li

Increasing disk space on VCSA

Over time your VCSA will run out of disk space and you will need to increase the disk space. I will describe how I have performed this on one of my PSC as I was alerted by my monitoring system. My environment is vSphere 6.0 U2. Log on to your PSC controller using the root account.  Run " Shell.set "  Run " shell  " Run the command " df -h" and you should get an output like the one below.  You can see that I have ran out of disk space on mount point "/storage/log". At this point I would go to the VM in web client to increase the relevant disk but when you look at the disks attached to the VM (11 in total) I can't tell which disk has the mount point of "/storage/log". After searching on VMware KB site I found an article which list which mount point resides on which disk So now you can see "/storage/log" is using "vmdk5" so now I can go and modify the disk size of "vmdk5" Hop back to t

Credential Guard/Device Guard preventing Workstation VMs to power on Windows 10

Like most people we all have VMware workstation on our laptops so that we can test new software or changes before going live. Recently my company enabled Credential Guard/Device Guard and it stopped my VMs from powering on. There is an article from VMware which documents how to turn off Credential Guard/Device Guard which works like a treat. Do follow all the steps especially if you have bit locker enabled on your laptop. If you don't remove Hyper-V correctly then you will get the famous blue screen. KB article to help disable Credential Guard/Device Guard https://kb.vmware.com/s/article/2146361 KB article from Microsoft to help if you do encounter a blue screen of death https://support.microsoft.com/en-ie/help/3189068/restart-failure-if-device-guard-or-credential-guard-isn-t-disabled-cor   Update : The VMware KB article now refers you to this Microsoft article where it guides you on how to turn on/off Credential Guard manually or via a powershell script which you can do
