  • 1.  ESXi host rename

    Posted Dec 07, 2020 06:35 PM

    We have a requirement to rename all ESXi hosts in a cluster. Hosts are connected to the distributed switch including mgmt network. vCenter is connected to SRM 

    Planning to follow the below steps. Please advise on this

    - Move the mgmt nw for the host from the distributed switch to std switch

    - Place the host in Maintenance mode

    - Disconnect and remove the host from vCenter

    - Modify the DNS record

    - Rename the host in DCUI 

    - Reconnect the host back to vCenter server.

    - Exit the host from Maintenance mode

    Thanks for the article.

    Just for confirmation. I need to migrate the mgmt network alone to std switch and for other networks of vMotion & VM networks, I can keep those in vDS and after rename of the host, it can be re-added to vDS without any issues.

     , yes that should be enough. The VM's don't have to move, as long as you are not changing anything related to uplinks from the dvSwitch.

    Just be careful: Disable DRS before destroying the cluster/removing the old FQDN of your ESXi hosts, Especially if it's set on fully automated.
