How do I Remove a Virtual Server

I have 3 ESX servers connected to a EMC SAN.  There are 3 virtual servers setup for failover via VMotion and HA.  I want to remove one of the Virtual servers and reallocate that space to the remaining two virutual servers.  I want to maintain the failover for the 2 remaing virtuals.  How do I remove a virtual server and maintain the failover for the remaining 2 virtual servers?How do I reallocate new free space to the existing virtual servers?

You want to delete a Virtual Machine?

Right Click the Virtual Machine, and click Delete from Disk, the storage will automatically be returned as free to the datastore.

okay, I think maybe you want to remove a Host ESX Server.

Right Click the Host Server and Click Remove, make sure all the virtual machines have been vMotioned off the server to other servers.

I do not understand "reallocate new free space to existing virtual servers".

Datastore are on the SAN, not on the host Servers?

Can you further explain what it is you're wanting to do @BiggieSmall? Your post is bit confusing. For clarification/terminology purposes, refer to your physical ESX or ESXi hosts as "hosts" (not virtual servers, if that's what you were meaning by 'virtual servers') and your virtual machines (that are probably a server of some sort) as just "VMs" or "virtual machines". Technically speaking, there is no such thing as a "virtual server". It's just kind of a made up word.

Now, that being said, please explain what it is you're wanting to accomplish. It sounds like you have 3 hosts, in a HA/DRS cluster, that use shared storage between the 3 hosts using a EMC Fibre Channel SAN, is that correct? Are you wanting to remove one of the hosts from the Cluster? To do so, you will need to either VMotion the VMs to other hosts in the Cluster, or power down the VMs, place the host in Maintenance Mode, then drag the host out of the Cluster (or rt-click on the host and select Remove). The only thing removing a host will do, if you not only remove it from the Cluster, but from vCenter, is free up licenses.

If you wanna reclaim datastore space, you will need to storage VMotion VMs to another datastore, or completely delete the VMs from the datastore (rt-click the VM and select 'Delete from Disk' as @hanccocka mentioned above). You may not instantly see the space reclaimed...you may have to "refresh" the view before you see the space show back up.

Please clarify if you're needing something different.
