  • Passed the VCIX-NV yesterday: tips, thoughts and recap

      VMware Certified Implementation Expert!   Well, I passed the VCIX-NV yesterday after about 2-3 weeks of study. This may have been one of the toughest certification tests that I have taken, but I appreciated the challenge throughout the process. In support, I don’t focus on NSX so I knew I had to put in more work and study time since I didn’t have any hands on experiencing prior to the Hands on Labs or ICM. Three weeks ago I set my mind to obtaining this certificate, so I scheduled the test before touching the product and gave myself just […]

  • NSX Manager SSL certificate replacement with CA

    During my study for the VCIX-NV exam I was writing a post on using the REST API client in Google Chrome when I hit an issue connecting to my NSX Manager via the API call. The error message that I received was below.   Could not get any response This seems to be like an error connecting to https://nsxmanager.vcloud.local/api/2.0/services/ssoconfig. The response status was 0. Check out the W3C XMLHttpRequest Level 2 spec for more details about when this happens.   After checking the certificate on NSX Manager, I noticed that the certificate showed localhost rather than the actual hostname for […]

  • What is a Platform Services Controller (PSC) in vSphere 6.x

      Platform Services Controller   With vSphere 6.0 introduced, along came the Platform Services Controller, or PSC for short. The best way to think of the PSC is Single Sign-On (SSO) plus more. What is “more” you ask? Let’s start with the deployment options. The PSC can be deployed as either a Windows Server or an Appliance. You can either embedded your PSC or use it as an external PSC (See Software and Hardware Requirements). In my opinion, I would always deploy the PSC externally because it will future proof your environment if your infrastructure is growing. For a list […]

  • vCenter Service crashes immediately after it starts

    A common vCenter issue seen is that vpxd will begin to crash immediately after it starts up. This usually starts after an initial crash or even just the restart of the service.

As such, this is a guide to finding out what went wrong!   Before diving right into it, let’s make sure you have the service set up to determine why it is crashing   Prerequisites   Turn off Service Recovery Options (Windows)   In a windows deployment, you might need to set the service […]

  • ESXi 6.0 SSL certificate replacement and management

    Note: As a prerequisite, the ESXi 6.0 server must have been a fresh install, and not an upgrade from a previous version.   ESXi CA certificates   If you are replacing your ESXi certificates with CA certificates, the best method is to make your VMCA a subordinate CA and allow it to sign certificates for the ESXi host. Please see directions here for making your VMCA a subordinate CA. I had received the error “Start Time Error” shown below. To resolve this I added the ESXi host to the domain, and added the VMCA certificate as a Trusted Publisher certificate […]

  • Unable to login to an External vCenter Appliance 6.0 with windows session credentials

    Anyone who is using the non-embedded version of the PSC appliance might notice that using Windows Session Credentials does not work when logging into vCenter with the C# client. The problem here is that even if the PSC is joined to the domain, the appliance VM housing the Web Client and vCenter is not. See here if you still need to join the PSC to a domain. Note: If you encounter this with an embedded PSC, try this VMware KB article   You will see error messages such as:   Windows Session credentials cannot be used to log into this […]

  • Interacting with the vPostgres Database in vSphere 6.0

    vPostgres in vCenter 6.0   Unlike earlier versions, vCenter 6.0 introduces a new default database for Windows installations, vPostgres. Some who have used the vCenter Appliance might recognize it, as it was adopted there in vCenter 5.0 Update 1 and above. vPostgres is an adapted version of PostgreSQL which very closely mimics its open source origins. For those used to SQL Management Studio, the interaction with this new database will be a bit different, but not difficult once you know the proper steps.   Connecting to a Windows vPostgres Database To start, we’ll go over how to use the built-in […]
