Error: No NIC found with MAC address…

-

Your HP server may runs fine on ESXi 4.x or 5.0, but you may get error message No NIC found with MAC address xx:xx:xx:xx:xx:xx after upgrade to ESXi 5.1 or later.

That’s caused by network adapter firmware, you have to upgrade server network adapter firmware by HP SPP 2013.02 or later. I would recommend you upgrade firmware of each component to this version, it’s pretty stable to run ESXi 5.1.

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.

It is easy to import WordPress content to Blogger.com. Some online tools can convert the exported WordPress XML to Blogger.com format. It took me 15 m

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
