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.

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
