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 IQN <iSCSI Qualified Name (IQN)> if the host was exported using iSCSI:

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.
