No.

If you needed to reboot everyone when you
added a node, then how could you ever form
a cluster with multiple nodes?

Hi Neelmani,

No, its not mandatory at all.
Both Adding as well as removing node from a cluster does not require
a reboot.

For information on cluster setup, Refer -
* Guidelines for OpenVMS Cluster Configurations

Hope this helps.

You can add or remove a node with no reboot required.

There are utilities to manage quorum (expected votes) which you should familiarize yourself with. See http://h71000.www7.hp.com/doc/os84_index.html and select your version of VMS for the appropriate cluster docs. In addition, the Availability Manager http://h71000.www7.hp.com/openvms/products/availman/index.html?jumpid=/products/openvms/availabilitymanager can force expected votes recalculation into a hung cluster.

Generally speaking: no.

Please review the referenced documentation concerning the the settings for votes.

Hi,

Adding the new node to cluster or removing the node from cluster does not requires the reboot of the entire cluster. Refer the below link for â Guidelines for OpenVMS Cluster Configurationsâ
