Unable to load status of objects in vCenter Server 5.1

-

On today's troubleshooting, I faced a very weird problem. vCenter Server services were up and running fine, it's able to connect by vSphere client, but VMs, hosts show gray, and I cannot power on VM via PowerCLI.

After went through each components of vCenter Server, I noticed the database size was 230GB, but only ~20 hosts were there. So I asked DBA team truncat event tables and shrink database. Issue gone after database optimization.

Moving to Blogger.com

-
My website was moved from WordPress to Blogger.com recently. I used to run my blog on Bluehost . It was a three years contract. To be honest,  the Bluehost service was super stable. The website only failed less than three times in the last three years. However, the renewal price was over $300. Hence, I started to explore an alternative. WordPress.com was an excellent option.

Try if you have time.  Eventually, I decided to go with Blogger.com . I need something stable and long-lasting. Blogger.com has been a Google service since 1997.

Connect-NsxtServer shows "Unable to connect to the remote server"

-
When you run Connect-NsxtServer in the PowerCLI, it may show "Unable to connect to the remote server".  Because the error message is a little bit confusing with other login issues. It's not easy to troubleshoot. The actual reason is the NSX-T uses a self-signed certificate, and the PowerCLI cannot accept the certificate automatically. The fix is super easy. You need to set the PowerCLI to ignore the invalid certificate with the following command: Set-PowerCLIConfiguration -Scope User -InvalidCertificateAction:Ignore -Confirm:$false
