After my „little“ homelab outage last year and the delivery of a new SSD I found some time to redeploy the nested cluster quite some time ago. During the preparation to my VCAP-DCV Deploy exam I deployed a second VCSA (vCenter Server Appliance) on my old Intel NUC and joined them to a single SSO domain to learn and try different things in the linked mode setup. That’s the reason why I received the „Could not connect to one or more vCenter Server Systems: https://<vcsaFQDN>:443/sdk“ every time I logged in to the second VCSA. Because I planned to redeploy the nested environment using the same IPs/FQDNs I wanted to make sure the orphaned VCSA is cleanly removed from the SSO configuration. This week one of my customers asked me for help with the same problem.A quick search and I found the following VMware KB article (again): Using the cmsso command to unregister vCenter Server from Single Sign-On (2106736). This time I decided to write a short blog post on the topic.Weiterlesen
Most of my customers now use tag-based backup with Veeam Backup & Replication to protect their business-critical applications and services. This ensures that they no longer need to perform any configuration within the backup software to protect their workloads. Only the individual adjustments of the Guest Credentials for Application-Aware Processing have to be done in the Veeam Console. The added value you have by doing this I have already covered in another blog post.
In the ever accelerating IT world and the changes that come along with it, it is extremely important for my customers to be able to make fast and reliable statements about the data backup status of certain systems. Since we use vSphere tags to perform nearly all of our backup administration from within vCenter, it would be consistent to have the appropriate status information available at this location as well. This is where the Notification Settings within the Advanced Backup Settings come into play. How you can configure simple status updates in vCenter without installing additional plug-ins or tools, and what you should consider when doing so, I‘ ll show you below.
In one of their latest updates for macOS Catalina Apple has introduced some new requirements for the acceptance of SSL certificates. The changes are documented here: https://support.apple.com/en-us/HT210176. This means that pages without a corresponding certificate are no longer accessible in Google Chrome. Unfortunately, the default vCenter Server certificate is one of the affected certificates. Unlike other certificate warnings, this error cannot be easily bypassed using Advanced options.
In the following I would like to show you how you can temporarily work around this issue.Continue reading „Bypass NET::ERR_CERT_REVOKED error in Google Chrome on macOS Catalina“
