Before removing a XenServer host from a pool, ensure that you shut down all the VMs running on that host. Otherwise, you may see a warning stating that the host cannot be removed.


Do not eject a host from a resource pool if it contains important data stored on its local disks. All of the data will be erased upon ejection from the pool. If you wish to preserve this data, copy the VM to shared storage on the pool first using XenCenter, or the xe vm-copy CLI command.

When a XenServer host containing locally stored VMs is ejected from a pool, those VMs will still be present in the pool database and visible to the other XenServer hosts. They will not start until the virtual disks associated with them have been changed to point at shared storage which can be seen by other XenServer hosts in the pool, or simply removed. It is for this reason that you are strongly advised to move any local storage to shared storage upon joining a pool, so that individual XenServer hosts can be ejected (or physically fail) without loss of data.
