================= Non-existent host ================= Problem ~~~~~~~ This error could be caused by a volume being exported outside of OpenStack using a host name different from the system name that OpenStack expects. This error could be displayed with the :term:`IQN ` if the host was exported using iSCSI. .. code-block:: console 2013-04-19 04:02:02.336 2814 ERROR cinder.openstack.common.rpc.common [-] Returning exception Not found (HTTP 404) NON_EXISTENT_HOST - HOST '10' was not found to caller. Solution ~~~~~~~~ Host names constructed by the driver use just the local host name, not the fully qualified domain name (FQDN) of the Compute host. For example, if the FQDN was **myhost.example.com**, just **myhost** would be used as the 3PAR host name. IP addresses are not allowed as host names on the 3PAR storage server.
