  • 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 […]

  • 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.

  • Joining the vCenter Server Appliance (VCSA) 6.0 to an Active Directory Domain

    Joining the vCenter Server Appliance to an Active Directory Domain in vSphere 6 is much different from in previous versions. Previously, you would use the Virtual Appliance Management Interface (VAMI) by navigating to the FQDN of the server over port 5480. In vSphere 6.0, you need to perform the steps through the vSphere Web Client. Once you know the new process, the task is relatively easy and quick.   Note: You can only join a PSC or VCSA with an embedded PSC to an AD domain.   Step 1. Navigate to the vSphere Client Web Client https://FQDN/vsphere-client   Step 2. […]

  • Single Sign On or Platform Services Controller (PSC) fails to install or upgrade with Error code 1603

      vCenter Single Sign-On Setup Wizard ended prematurely because of an error   Ah, the famous 1603 error code when installing or upgrading the PSC or SSO server. Unfortunately, this is not a clear cut error code, nor is there one way to fix the issue. In fact this error code is so generic you typically need to review other log files to understand what may be happening. That being said, I wanted to compile a one stop shop for troubleshooting this error code, what errors the logs show and any resolutions I have found.   The typical error messages […]

      Error 1009 in vSphere Web Client   An error that frequently comes up in the vSphere Web Client is Error 1009. This issue occurs in vCenter Server 5.1, 5.5, and 6.0 when navigating through inventory. Typically when this error message pops up you have to refresh your entire session. This issue is almost always caused by cached objects with bad references. These cached objects are stored in the SerenityDB folder under the users name, if by chance any of the cached objects are deleted, but the cache still exists, you get bad Object ID references which will crash the […]
