Hello There, In this article, i am covering how to migrate the ESXi host switch from N-VDS to VDS 7.0 switch in NSX-T 3.2.x version. When using N-VDS as the host switch, NSX-T is represented as an opaque network in vCenter Server . N-VDS owns one or more of the physical interfaces (pNICs) on the transport node, and port configuration is performed from NSX-T Data Center . You can migrate your host switch to vSphere Distributed Switch (VDS) 7.0 for optimal pNIC usage and manage the networking for NSX-T hosts from vCenter Server . When running NSX-T on a VDS switch, a segment is represented as an NSX-T Distributed Virtual Port Groups. Any changes to the segments on the NSX-T network are synchronized in vCenter Server. We have an NSX-T environment running with NSX-T 3.2.2.1 version. this environment was designed and implemented with NSX-T 2.x version and that time we used the N-VDS as host switch configuration on the transport nodes bcuz VDS was not supported that time.
Issue details:- Password remediation tasks on SDDC manager getting failed with below error. However, we are able to connect SSH with root password on the vROPS appliances, no issues with credentials. I checked Operations logs on SDDC manager and found below logs, indicating the SSH connectivity issues from SDDC to vROPS appliances. Tried to do SSH vROPS appliance from SDDC manager, getting below error... Seems some issue with ECDSA key.. Resolution:- SSH to vROPS appliance and retrieve the ECDSA ssh keys as below. Now, we have 2 options to update the correct SSH keys for vROPS appliance on SDDC manager known_Hosts files located at below location. /root/.ssh/known_hosts /etc/vmware/vcf/commonsvcs/known_hosts /home/vcf/.ssh/known_hosts /opt/vmware/vcf/commonsvcs/defaults/hosts/known_hosts First option is manually copy and paste the SSH key on all the known_hosts files and restart the SDDC manager services and then try to remediate the password again. it will be successful this
You can import an unmanaged virtual machine to a vRealize Automation environment. An unmanaged virtual machine exists in a vCenter but is not managed in a vRealize Automation environment and cannot be viewed in the vRA portal . Once you import an unmanaged virtual machine, the virtual machine is managed by using the vRealize Automation management interface. you can see the virtual machine on the Managed Machines tab or the Items tab. Please follow below steps to Import/Register VM into a vRA portal. Log in to vRealize Automation as a fabric administrator and as a business group manager. If you are importing virtual machines that use static IP addresses, prepare a properly configured address pool. If you use bulk import to import a virtual machine with a static IP address that is allocated to another virtual machine, the import fails. Create a Blueprint and should not have even network attached as well. See below snapin. Create Network profile that shoul
