The cinder.volume.drivers.violin.v6000_iscsi Module

Violin Memory iSCSI Driver for Openstack Cinder

Provides iSCSI specific LUN services for V6000 series flash arrays.

This driver requires VMOS v6.3.0.4 or newer software on the array.

You will need to install the Violin Memory REST client library: sudo pip install vmemclient

Set the following in the cinder.conf file to enable the VMEM V6000 ISCSI Driver along with the required flags:

volume_driver=cinder.volume.drivers.violin.v6000_iscsi.V6000ISCSIDriver

NOTE: this driver file requires the use of synchronization points for certain types of backend operations, and as a result may not work properly in an active-active HA configuration. See OpenStack Cinder driver documentation for more information.

class V6000ISCSIDriver(*args, **kwargs)
