FC Traffic Drops After IOM Reset/Reseat/Cable Pull or UCS Upgrade

-
I just found a Cisco KB descripts a firmware issue may impact to ESXi FC storage performance. Please have a look whether your Cisco UCS system firmware is 2.1(2a), 2.1(2c), or 2.1(2d).



I checked my 2.1(3a), the out of order is not there, so it's looks  like only impact the particular version mentioned in KB.

我刚刚找到一个固件问题导致光纤存储性能下降的思科知识库，你可以看看你的Cisco UCS固件版本是不是2.1(2a)、2.1(2c)、2.1(2d)。

我刚才检查 了一下我的2.1（3a）版本，顺序错乱的问题并不存在，看起来这个问题只影响特定的固件版本哦。

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. However, I experienced it a few years ago. I want to try something new. GitHub Pages is a trendy blog service. But it needs to be simpler to set up. 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 long enough to prove the service's stability. And it is free to use with some advanced features. Such as the custom domain, SSL and AdSense, etc... 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
