EMC VNX plugin for Fuel extends Mirantis OpenStack functionality by adding support for EMC VNX arrays in Cinder using iSCSI protocol. It replaces Cinder LVM driver which is the default volume backend that uses local volumes managed by LVM.
|Mirantis OpenStack compatibility||9.0|
Since only one storage network is available in Fuel 6.x on OpenStack nodes, multipath will bind all storage paths from EMC on one network interface. In case this NIC fails, the communication with storage is lost.
Before starting a deployment you have to preconfigure EMC VNX array and connect it properly to the environment. Both EMC SP IPs and all iSCSI ports should be available over storage interface from OpenStack nodes. To learn more about EMC VNX configuration, see the official EMC VNX series documentation
EMC VNX configuration checklist:
To install EMC VNX plugin, follow these steps:
Download the plugin from Fuel Plugins Catalog
Copy the plugin on already installed Fuel Master node; ssh can be used for that. If you do not have the Fuel Master node yet, see Quick Start Guide:
# scp emc_vnx-4.0-4.0.0-0.noarch.rpm root@<Fuel_master_ip>:/tmp
Log into the Fuel Master node. Install the plugin:
# cd /tmp # fuel plugins --install emc_vnx-4.0-4.0.0-0.noarch.rpm
Check if the plugin was installed successfully:
# fuel plugins id | name | version | package_version ---|---------|---------|---------------- 1 | emc_vnx | 4.0.0 | 4.0.0
