The cinder.volume.drivers.violin.v7000_iscsi Module

Violin 7000 Series All-Flash Array iSCSI Volume Driver

Provides ISCSI specific LUN services for V7000 series flash arrays.

This driver requires Concerto v7.5.4 or newer software on the array.

You will need to install the python VMEM REST client: sudo pip install vmemclient

Set the following in the cinder.conf file to enable the VMEM V7000 ISCSI Driver along with the required flags:

volume_driver=cinder.volume.drivers.violin.v7000_iscsi.V7000ISCSIDriver

class V7000ISCSIDriver(*args, **kwargs)

Bases: cinder.volume.driver.ISCSIDriver
