The Dell Storage Center volume driver interacts with configured Storage Center arrays.
The Dell Storage Center driver manages Storage Center arrays through
Enterprise Manager. Enterprise Manager connection settings and Storage
Center options are defined in the cinder.conf file.
Prerequisite: Dell Enterprise Manager 2015 R1 or later must be used.
The Dell Storage Center volume driver provides the following Cinder volume operations:
Create, delete, attach (map), and detach (unmap) volumes.
Create, list, and delete volume snapshots.
Create a volume from a snapshot.
Copy an image to a volume.
Copy a volume to an image.
Clone a volume.
Extend a volume.
Use the following instructions to update the configuration file for iSCSI:
Example 2.3. Sample iSCSI Configuration
default_volume_type = delliscsi enabled_backends = delliscsi [delliscsi] # Name to give this storage backend volume_backend_name = delliscsi # The iSCSI driver to load volume_driver = cinder.volume.drivers.dell.dell_storagecenter_iscsi.DellStorageCenterISCSIDriver # IP address of Enterprise Manager san_ip = 172.23.8.101 # Enterprise Manager user name san_login = Admin # Enterprise Manager password san_password = secret # The Storage Center iSCSI IP address iscsi_ip_address = 192.168.0.20 # The Storage Center serial number to use dell_sc_ssn = 64702 # ==Optional settings== # The Enterprise Manager API port dell_sc_api_port = 3033 # Server folder to place new server definitions dell_sc_server_folder = devstacksrv # Volume folder to place created volumes dell_sc_volume_folder = devstackvol/Cinder # The iSCSI IP port iscsi_port = 3260
Use the following instructions to update the configuration file for fibre channel:
Example 2.4. Sample FC configuration
default_volume_type = dellfc enabled_backends = dellfc [dellfc] # Name to give this storage backend volume_backend_name = dellfc # The FC driver to load volume_driver = cinder.volume.drivers.dell.dell_storagecenter_fc.DellStorageCenterFCDriver # IP address of Enterprise Manager san_ip = 172.23.8.101 # Enterprise Manager user name san_login = Admin # Enterprise Manager password san_password = secret # The Storage Center serial number to use dell_sc_ssn = 64702 # Optional settings # The Enterprise Manager API port dell_sc_api_port = 3033 # Server folder to place new server definitions dell_sc_server_folder = devstacksrv # Volume folder to place created volumes dell_sc_volume_folder = devstackvol/Cinder
