Reason for recalling VMWare vSphere 7.0 U3 Version

VMware just recalled their latest update for vSphere and vCenter Server 7.0 U3b is no longer available for download. If your vCenter has already been upgraded to vCenter 7.0 U3b\and is experiencing the symptoms mentioned in KB 86191, please remove the i40enu driver.
Issues
  • After patching ESXi to 7.0 Update 3 - HA can no longer be successfully enabled
  • When trying to enable HA, the installation of the HA agent (FDM) starts, and the status switches into "Waiting for cluster election to complete", only to fail and start over again
  • The HA status for the ESXi host is stuck at "Uninitialized"
  • In some cases the HA enablement task fails with "Cannot find vSphere HA master agent"
  • Migrating or powering on VMs in an HA enabled cluster fail
  • In /var/run/log/esxupdate.log on the ESXi, you find the following entries:

Cause
  • This issue occurs when both the i40en and i40enu VIBs for the inbox Intel network driver are installed on the host
  • The issue was also reported after upgrading to vCenter 7.0 Update 3b, released on 12th November 2021, which is no longer available.
  • In vSphere 7.0 Update 2, the driver was renamed from i40en to i40enu. Starting with vSphere 7.0 Update 3, the inbox i40enu network driver for ESXi changes back to i40en
Resolution
This issue will be resolved in an upcoming release of VMware ESXi.
The issue was also resolved in VMware ESXi 7.0 U3b build 18905247 (No longer available)
Note:- vSphere ESXi 7.0 U3, U3a, and U3b and vCenter 7.0 U3b are no longer available for download due to several critical issues identified in them. For information regarding this decision, Please refer to KB 86398 
Temporary Solution
To work around the issue, remove the conflicting i40enu driver
  1. Disable vSphere HA on the cluster with the affected hosts.
  2. Put the ESXi in maintenance mode, then run the following command to remove the obsolete i40enu VIB :
esxcli software vib remove --vibname=i40enu
  1. Once the VIB has been removed, reboot the ESXi host.
  2. When this has been done for all hosts in the cluster, HA can be enabled again.

Link State Routing Protocol

Link state routing is a method in which each router shares its neighborhood’s knowledge with every other router on the internetwork. In this algorithm, each router in the network understands the network topology and then makes a routing table depending on this topology. Each router will share data about its connection to its neighbor, who will, consecutively, reproduce the data to its neighbors, etc. This appears just before all routers have constructed a topology of the network. In LSP, each node transmits its IP address and the MAC to its neighbor with its signature. Neighbors determine the signature and maintain a record of the combining IP address and the MAC. The Neighbor Lookup Protocol (NLP) of LSP derives and maintains the MAC and IP address of every network frame accepted by a node. The extracted data can support the mapping of MACs and IP addresses. The link-state flooding algorithm prevents the general issues of broadcast in the existence of loops by having every node mainta...

Matter: A next generation home standard

The smart home is evolving. To date, if you've wanted to get into developing a smart home, you've had to deal with the multitude of smart home ecosystems, and making sure that each device you buy is compatible. That, however, may soon change — thanks to new smart home standard called Matter. Matter isn't available just yet, but when it is finally released, it could completely change how you buy smart home products, for the better. All of the best smart home devices could soon support the standard, helping them all work together nicely, and ensuring that no matter what products you buy, you'll be able to use them. Matter is basically the name of a new smart home connectivity standard . But this standard is a little unlike others. That's because of the fact that it's being developed by the Connectivity Standards Alliance, which counts hundreds of companies as members. That includes the likes of Google, Alexa, and Apple. So, whether you prefer to use Google Assista...

New interactive stickers for Stories

Instagram has introduced several new features to Stories, offering interactive ways to share music, photos, and videos. One of the most interesting additions is a feature called Reveal , which blurs the content of a story post and requires viewers to DM the person who shared it in order to see it. Instagram's head, Adam Mosseri, has emphasized the importance of direct messages on the platform, with stories and DMs driving most of Instagram's growth. Requiring a DM to view content represents the next step in boosting engagement, and creators are likely to use it as a tactic to increase their stories' engagement. Another new feature, Frames, adds a Polaroid overlay to images that initially appear gray. Users can shake their phone to reveal the photo, resembling the process many people associate with Polaroid pictures, despite the fact that shaking Polaroids is not recommended by the company during development. Instagram has also introduced a music-based template feature calle...
