NEC Storage V series driver

NEC Storage V series driver provides Fibre Channel and iSCSI support for NEC V series storages.

System requirements

Supported models:

Storage model Firmware version
V100, V300 93-04-21 or later

Required storage licenses:

  • iStorage Local Replication Local Replication Software

Supported operations

  • Create, delete, attach, and detach volumes.
  • Create, list, and delete volume snapshots.
  • Create a volume from a snapshot.
  • Create, list, update, and delete consistency groups.
  • Create, list, and delete consistency group snapshots.
  • Copy a volume to an image.
  • Copy an image to a volume.
  • Clone a volume.
  • Extend a volume.
  • Migrate a volume.
  • Get volume statistics.
  • Efficient non-disruptive volume backup.
  • Manage and unmanage a volume.
  • Attach a volume to multiple instances at once (multi-attach).
  • Revert a volume to a snapshot.

Note

A volume with snapshots cannot be extended in this driver.

Configuration

Set up NEC V series storage

You need to specify settings as described below for storage systems. For details about each setting, see the user's guide of the storage systems.

Common resources:

  • All resources

    All storage resources, such as DP pools and host groups, can not have a name including blank space in order for the driver to use them.

  • User accounts

    Create a storage device account belonging to the Administrator User Group.

  • DP Pool

    Create a DP pool that is used by the driver.

  • Resource group

    If using a new resource group for exclusive use by an OpenStack system, create a new resource group, and assign the necessary resources, such as LDEVs, port, and host group (iSCSI target) to the created resource.

  • Ports

    Enable Port Security for the ports used by the driver.

If you use iSCSI:

  • Ports

    Assign an IP address and a TCP port number to the port.

Set up NEC V series storage volume driver

Set the volume driver to NEC V series storage driver by setting the volume_driver option in the cinder.conf file as follows:

If you use Fibre Channel:

[Storage1]
volume_driver = cinder.volume.drivers.nec.v.nec_v_fc.VStorageFCDriver
volume_backend_name = Storage1
san_ip = 1.2.3.4
san_api_port = 23451
san_login = userid
san_password = password
nec_v_storage_id = 123456789012
nec_v_pool = pool0

If you use iSCSI:

[Storage1]
volume_driver = cinder.volume.drivers.nec.v.nec_v_iscsi.VStorageISCSIDriver
volume_backend_name = Storage1
san_ip = 1.2.3.4
san_api_port = 23451
san_login = userid
san_password = password
nec_v_storage_id = 123456789012
nec_v_pool = pool0

This table shows configuration options for NEC V series storage driver.

cinder.volume.drivers.nec.v.nec_v_rest

Required options

  • san_ip

    IP address of SAN controller

  • san_login

    Username for SAN controller

  • san_password

    Password for SAN controller

  • nec_v_storage_id

    Product number of the storage system.

  • nec_v_pool

    Pool number or pool name of the DP pool.
