VMware vSphere | ESXi Host | Namespace error while entering host into Maintenance

Hello Techies! Welcome to Says Tech! In this blog, we will be dealing with an issue which we face while putting/exiting the host to or from maintenance mode. Description: After upgrade to vSphere 7, I found that my ESXi hosts were no longer able to go into maintenance mode and vice-versa. Maintenance task fails and it throws an error every time while putting or exiting the host to or from maintenance mode: Host cannot enter maintenance mode because it failed to enter Namespaces maintenance mode on the node.   Possible Cause: This can be happen if your environment is recently upgraded to vSphere 7 and the Workload Control Plan (WCP) service is either stopped or stuck. Troubleshooting Steps: 1) Access VAMI console by navigating to https://<vcenter_name_fqdn>:5480/ then click Services 2) Scroll down and check for WCP (Workload Control Plan) service status 4) Click on Start if it is stopped, or click Restart if it is already started or stuck 5) Try to put the host in Maintenance Mode

  Hello Techies! Welcome to Says Tech! In this blog, I will show you to handle the ESXi upgrade issue caused by VIBs installed and the procedure to remove them! De scription: During patch remediation from VMware Update Manager or Lifecycle Manager, it aborted the process by throwing some error: The upgrade has VIBs that are missing dependencies. Remove the VIBs or use Image Builder to create a custom upgrade ISO image that contains the missing dependencies, and try to upgrade again . Software or system configuration of host is incompatible. Check scan results for details. Troubleshooting Steps: 1. Check the scan output from "Updates" tab on the target ESXi host 2. SSH to the target ESXi host and run below command and check the mentioned VIBs                 esxcli software vib list 3. Remove the impacted vib by running below command:                     esxcli software vib remove -n <vib-name> 4. Perform a host reboot before running the upgrade again. Enjoy! Thanks, Arv
