Hello. Hoping to find some help with an issue in my attempt to use an
Equallogic array for a storage back end for Cinder with OpenStack Grizzly.
Since the Crowbar Grizzly release is not complete yet, we are trying to
use the Rackspace Private Cloud installer tool and so far it has worked
very well. Using it with a Ceph storage back end worked great but we
want to see how things work with Equallogic.
We have a fresh Equallogic running 6.0.2 release firmware and have
installed the eqlx.py into the appropriate driver location for the
Cinder setup. The config is all in place and we can start the Cinder
volume service just fine. Creating and deleting volumes works as well.
The problem comes when we try to actually use the Equallogic to actually
have the controller node or compute node login to an iSCSI volume to put
data on it (such as making a volume from an image). The log result is as
follows:
2013-08-01 13:46:20 ERROR [cinder.volume.manager] Error: ['Traceback

I'm no programmer but from what I can tell, it seems the eqlx driver is
somehow causing Cinder-volume to try to run the iscsiadm command at the
end of that log entry via SSH on the Equallogic shell. Obviously that
won't work but I can't figure out why it is happening.
Any insights?
Thanks
