After a broker node or compute node is removed from an IVX cluster, it remains connected to the Central Management appliance as an available node. The node serves no purpose until it is added to another IVX cluster.
Prerequisites
Operator or Admin access to the Central Management appliance
If the node you are removing is the only broker node, enable another broker node.
Removing a node from a cluster using the Web UI
Use the Appliances > Clusters page or the Appliances > Nodes page to remove a broker node or compute node from an IVX cluster.
Using the clusters page to remove a node
To remove a broker or compute node:
Log in to the Central Management Web UI.
Select Appliances > Clusters.
Click the Actions menu, and then click Edit.
Click the icon to move the node from the Selected list to the Available list.
Click Next.
Modify broker assignments if necessary, and then click Update.
Using the nodes page to remove a node
To remove a broker or compute node:
Log in to the Central Management Web UI.
Select Appliances > Nodes.
Click the Actions menu, and then click Remove.
When prompted, click REMOVE to confirm that you want to remove the node.
Removing a node from a cluster using the CLI
Use the commands in this section to remove a broker node or compute node from an IVX cluster.
To remove a broker or compute node:
Log in to the Central Management CLI.
Enable the CLI configuration mode:
cm-hostname > enable cm-hostname # configure terminal
Remove the node:
cm-hostname (config) # no cmc mvx <cluster name> node <node name>
Verify your change:
cm-hostname (config) # show cmc mvx cluster <cluster name> nodes
Example
The following example removes the vx-2 from Cluster-Acme.
cm-1 (config) # no cmc mvx cluster Cluster-Acme node vx-2Removing a node from a cluster on an offline Central Management appliance using the CLI
Use the commands in this section to remove a broker node or compute node from an IVX cluster that is managed by an offline Central Management appliance.
To remove a broker or compute node:
Log in to the Virtual Execution CLI.
Enable the CLI configuration mode:
vx-hostname > enable vx-hostname # configure terminal
Remove this node:
vx-hostname (config) # mvx node detachRemove this node or another node in the cluster:
vx-hostname (config) # mvx node detach <node>
Example
The following example removes the vx-2 node from the cluster.
vx-1 (config) # mvx node detach vx-2
