You might need to remove a data node or remote collector node from a vRealize Operations Manager cluster as part of resizing or maintaining your deployment.


You cannot remove the vRealize Operations Manager master node. In addition, you cannot remove a replica node using this procedure. To remove a replica node, see Remove High Availability.

Note any adapters that are installed on the node, in case you want to reinstall those adapters on another node. Removing a node also removes the adapter connections supported by that node.


In a Web browser, navigate to the vRealize Operations Manager administration interface at https://master-node-name-or-ip-address/admin.


Log in with the admin username and password for the master node.


Under Nodes in the vC Ops Cluster, select the node to remove.


If it is online, take the node offline.


Click the red X to remove the node.

vRealize Operations Manager rebalances the cluster.

Removing a node does not decommission the node because sensitive files, such as certificate files, remain on the node.

For security, if you do not expect to re-add the node to the cluster, take one of the following precautions.

Safeguard access to the node.

Securely delete it if it is a virtual machine.

Securely erase the disk if it is a physical machine.
