How to remove one cluster node in enterprise vault

Created: 22 Jan 2012 • Updated: 31 Jan 2012 | 5 comments
This issue has been solved. See solution.

Hi,

We have a four-node microsoft cluster for our enterprise vault and we need to evict one node.

Please let us know if there is a article to follow else if anybody has done it successfully, please share the steps.

We have both enterprise vault and SQL 2005 in this cluster. So we need to remove both the applications from this node.

Rgds, Guru.

The cluster nodes are administered via MCS or VCS. EV only needs to have a supported configuration as detailed in the Install / Config guide for whatever version of EV you have:

Hi Percy, I am not finding any where a procedure to evict a node from the cluster while it is an Entprise Vault node.

I found this mention saying "You cannot remove Enterprise Vault services in a clustered configuration" in Installing and Configuring document. I am not understanding what really does this mean.

Does this also mean that one cannot evict a node from cluster which is participating in Enterprise Vault service?

Evicting a node from a cluster is not an EV function but one within your cluster admin application. For example here is the guide for Microsoft: http://technet.microsoft.com/en-us/library/cc784955(WS.10).aspx

Whet the Install / Config guide means is that you cannot remove the services that are created as a shared resource within the cluster as this will stop EV functioning. Services are shared between each node so if a node fails then servuces swap over to the other node i.e they switch from the active node to the passive node.

In any cluster configuration you require at least two nodes, the way they are configured is up to you but obviously they must in a supported configuration as per the EV install/config guide. So as long as you have two nodes then you should be ok to remove other nodes. If you only have two nodes then you cannot remove that node.

Got the old node removed from the cluster service by first uninstalling the EV binaries and then evicting the node from the MSCS. Observed for a day and found all working fine. Thank you for letting me know its a straight forward procedure, because the same when we are adding a node to existing EV cluster, we run the config wizard and make the new node part of EV service. But for removing the node from the cluster doesnt require any wizard to run.
