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

Unless you really know what you're doing, make sure that only one greenthread can read any particular socket.
Consider using a pools.Pool. If you do know what you're doing and want to disable this error,

You need to update your copy of the hp_3par_fc.py driver
which contains the synchronization code.
