The Infortrend volume driver is a Block Storage driver providing iSCSI and Fibre Channel support for Infortrend storages.

The Infortrend volume driver supports the following volume operations:

• Create, delete, attach, and detach volumes.
• Create and delete a snapshot.
• Create a volume from a snapshot.
• Copy an image to a volume.
• Copy a volume to an image.
• Clone a volume.
• Extend a volume
• Retype a volume.
• Manage and unmanage a volume.
• Migrate a volume with back-end assistance.
• Live migrate an instance with volumes hosted on an Infortrend backend.

To use the Infortrend volume driver, the following settings are required:

• Create logical volumes in advance.
• Host side setting Peripheral device type should be No Device Present (Type=0x7f).

• Install Oracle Java 7 or later.
• Download the Infortrend storage CLI from the release page, and assign it to the default path /opt/bin/Infortrend/.

On cinder-volume nodes, set the following in your /etc/cinder/cinder.conf, and use the following options to configure it:

[DEFAULT]
default_volume_type = IFT-ISCSI
enabled_backends = IFT-ISCSI

[IFT-ISCSI]
volume_driver = cinder.volume.drivers.infortrend.infortrend_iscsi_cli.InfortrendCLIISCSIDriver
volume_backend_name = IFT-ISCSI
infortrend_pools_name = POOL-1,POOL-2
san_ip = MANAGEMENT_PORT_IP
infortrend_slots_a_channels_id = 0,1,2,3
infortrend_slots_b_channels_id = 0,1,2,3

[DEFAULT]
default_volume_type = IFT-FC
enabled_backends = IFT-FC

[IFT-FC]
volume_driver = cinder.volume.drivers.infortrend.infortrend_fc_cli.InfortrendCLIFCDriver
volume_backend_name = IFT-FC
infortrend_pools_name = POOL-1,POOL-2,POOL-3
san_ip = MANAGEMENT_PORT_IP
infortrend_slots_a_channels_id = 4,5

• Enable multipath for image transfer in /etc/cinder/cinder.conf.

  use_multipath_for_image_xfer = True

  Restart the cinder-volume service.

• Enable multipath for volume attach and detach in /etc/nova/nova.conf.

  [libvirt]
  ...
  volume_use_multipath = True
  ...

  Restart the nova-compute service.

• infortrend:provisioning - Defaults to full provisioning, the valid values are thin and full.

• infortrend:tiering - Defaults to use all tiering, the valid values are subsets of 0, 1, 2, 3.

  If multi-pools are configured in cinder.conf, it can be specified for each pool, separated by semicolon.

  For example:

  infortrend:provisioning: POOL-1:thin; POOL-2:full

  infortrend:tiering: POOL-1:all; POOL-2:0; POOL-3:0,1,3
