Jay S. Bryant e9857d616d Migrate the blockstorage admin-guide to Cinder
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.

===================
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.
