TOYOU NetStor Cinder driver

TOYOU NetStor series volume driver provides OpenStack Compute instances with access to TOYOU NetStor series storage systems.

TOYOU NetStor storage can be used with iSCSI or FC connection.

This documentation explains how to configure and connect the block storage nodes to TOYOU NetStor series storage.

Driver options

The following table contains the configuration options supported by the TOYOU NetStor iSCSI/FC driver.

Description of TOYOU NetStor configuration options

Configuration option = Default value	Description
acs5000_copy_interval = 5	(Integer(min=3, max=100)) When volume copy task is going on,refresh volume status interval
acs5000_multiattach = False	(Boolean) Enable to allow volumes attaching to multiple hosts with no limit.
acs5000_volpool_name = [pool01]	(List of String) Comma separated list of storage system storage pools for volumes.

Supported operations

• Create, list, 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.

• Migrate a volume.

• Manage/Unmanage volume.

• Revert to Snapshot.

• Multi-attach.

Configure TOYOU NetStor iSCSI/FC backend

This section details the steps required to configure the TOYOU NetStor storage cinder driver.

1. In the cinder.conf configuration file under the [DEFAULT] section, set the enabled_backends parameter with the iSCSI or FC back-end group.

   • For Fibre Channel:

     [DEFAULT]
     enabled_backends = toyou-fc-1
     

   • For iSCSI:

     [DEFAULT]
     enabled_backends = toyou-iscsi-1
     

2. Add a backend group section for the backend group specified in the enabled_backends parameter.

3. In the newly created backend group section, set the following configuration options:

   • For Fibre Channel:

     [toyou-fc-1]
     # The TOYOU NetStor driver path
     volume_driver = cinder.volume.drivers.toyou.acs5000.acs5000_fc.Acs5000FCDriver
     # Management IP of TOYOU NetStor storage array
     san_ip = 10.0.0.10
     # Management username of TOYOU NetStor storage array
     san_login = cliuser
     # Management password of TOYOU NetStor storage array
     san_password = clipassword
     # The Pool used to allocated volumes
     acs5000_volpool_name = pool01
     # Backend name
     volume_backend_name = toyou-fc
     

   • For iSCSI:

     [toyou-iscsi-1]
     # The TOYOU NetStor driver path
     volume_driver = cinder.volume.drivers.toyou.acs5000.acs5000_iscsi.Acs5000ISCSIDriver
     # Management IP of TOYOU NetStor storage array
     san_ip = 10.0.0.10
     # Management username of TOYOU NetStor storage array
     san_login = cliuser
     # Management password of TOYOU NetStor storage array
     san_password = clipassword
     # The Pool used to allocated volumes
     acs5000_volpool_name = pool01
     # Backend name
     volume_backend_name = toyou-iscsi
