• Combining High Availability and Multisite PSCs in vSphere 6

    There has been some confusion around creating a combined Highly Available and Multisite topology in vSphere 6.0. Its true that you can create a fully replicating string of PSCs right from the installation. However, the problem is that a default replication agreement only exists between two PSCs. So what happens when you have more than two? This offers limited redundancy options when one fails. The solution to this is to manually create a ring topology after the PSCs are installed. You might note that I’m using ring over mesh. The reasoning behind this is to limit the amount of replication […]

  • Repointing vCenter 6.0 U1 to a Platform Services Controller (PSC) in a Different Site

      With 6.0 Update 1, a feature that allows repointing of a standalone vCenter server to a external PSC was also released. You might be thinking “But I could already do that, couldn’t I?”   The answer to that is Yes and No.   Yes, a repoint was possible before Update 1. The catch being that the PSC must have been installed in the same SSO site as well as domain. Meaning that if the PSC was not in what is considered an HA deployment without a load balancer, a repoint was not workable. In this article, I will explain […]

  • Migrating a DVS and Host from one vCenter to another.

    There are mixed feelings about exporting a DVS from one vCenter Server to another. Some will tell you that it absolutely cannot be done, while others will tell you that it works great, and even go so far as to mention it saving their environment. Personally, I’m on the fence about this. There are not many statements on the supportability of this one way or another by VMware, so I interpret it as sitting in the realm of “Document what you DO support, not what you don’t.”   With that said, this guide should be used with great caution and […]

  • vCenter Server 6.0 Log Locations

    vSphere 6.0 has made some significant changes to the logging locations for its contained vCenter and PSC services. Everything has been condensed into a common area of the directory structure and labeled with the service name. In short, it makes a LOT more sense now than it did before.   This is an overview of what the structure looks like now and where to find what you need.   Windows Log Locations   C:\ProgramData\VMware\vCenterServer\logs     vCenter Appliance Log Locations   /var/log/vmware     Note: For the purpose of brevity, all log locations will be referenced from the base logs […]

  • 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. It can seem random. But of course, almost nothing is “random” in tech industry. 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 […]

  • 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 […]
