  • How to remove a single ESX host from a HA Cluster

    Hi,

    We have ESX 3.5 U4 in our environment. We also have several HA and DRS clusters. Each cluster has 13 nodes with 1 failover capacity. Now I want to know the procedure to enable and disable HA for a single host. I do not want to break HA entirely for the cluster while enabling or disabling HA.

    Please tell me the steps to enable and disable HA for a single host.

    Thanks in advance

    Hi,

    I think that you should remove the host from the cluster .... I am not sure if there is a way to remove HA or DRS from a host in a cluster which is enabled with these features .....

      HA and DRS are set at the cluster level and not at the HOST level.

        You cannot disable for only one host in the cluster.

        If you do not want that host to participate in HA then you will have to remove it from the cluster.

        The server either acts as part of the Cluster - with DRS/HA or as a stand-alone host under the datacenter.

        This does not mean that you cannot vmotion vm's between a stand-alone and a cluster. (you might get into issues with CPU masking if the hosts are not the same though).
