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.

Failed to connect volume in FC SAN

Problem

The compute node failed to connect to a volume in a Fibre Channel (FC) SAN configuration. The WWN may not be zoned correctly in your FC SAN that links the compute host to the storage array:

Solution

The network administrator must configure the FC SAN fabric by correctly zoning the WWN (port names) from your compute node HBAs.
