This patch is part of the docs migration for Cinder. It is more or less a drag and drop of the docs from openstack-manuals admin-guide directory. I needed to change some syntax to work with Cinder's more stringent doc build. Note that the purpose of this patch is just to get the documentation back to an accessible location. Later patches will clean up the organization and content. Change-Id: Ib3f9255e0f9f2ff42a0ee4126607ff319a3d901e

Duplicate 3PAR host
|
|
===================
|
|
|
|
Problem
|
|
~~~~~~~
|
|
|
|
This error may 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 <iSCSI Qualified Name
|
|
(IQN)>` if the host was exported using iSCSI:
|
|
|
|
.. code-block:: console
|
|
|
|
Duplicate3PARHost: 3PAR Host already exists: Host wwn 50014380242B9750 \
|
|
already used by host cld4b5ubuntuW(id = 68. The hostname must be called\
|
|
'cld4b5ubuntu'.
|
|
|
|
Solution
|
|
~~~~~~~~
|
|
|
|
Change the 3PAR host name to match the one that OpenStack expects. The
|
|
3PAR host constructed by the driver uses 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.
