Infortrend volume driver

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

Supported operations

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.

System requirements

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

Set up Infortrend storage

  • Create logical volumes in advance.

  • Host side setting Peripheral device type should be No Device Present (Type=0x7f).

Set up cinder-volume node

  • Install JRE 7 or later.

  • Download the Infortrend storage CLI from the release page. Choose the raidcmd_ESDS10.jar file, which’s under v2.1.3 on the github releases page, and assign it to the default path /opt/bin/Infortrend/.

Driver configuration

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

Driver options

Description of Infortrend volume driver configuration options

Configuration option = Default value



infortrend_cli_max_retries = 5

(Integer) The maximum retry times if a command fails.

infortrend_cli_path = /opt/bin/Infortrend/raidcmd_ESDS10.jar

(String) The Infortrend CLI absolute path.

infortrend_cli_timeout = 60

(Integer) The timeout for CLI in seconds.

infortrend_cli_cache = False

(Boolean) The Infortrend CLI cache. Make sure the array is only managed by Openstack, and it is only used by one cinder-volume node. Otherwise, never enable it! The data might be asynchronous if there were any other operations.

infortrend_pools_name = None

(String) The Infortrend logical volumes name list. It is separated with comma.

infortrend_iqn_prefix =

(String) Infortrend iqn prefix for iSCSI.

infortrend_slots_a_channels_id = None

(String) Infortrend raid channel ID list on Slot A for OpenStack usage. It is separated with comma.

infortrend_slots_b_channels_id = None

(String) Infortrend raid channel ID list on Slot A for OpenStack usage. It is separated with comma.

java_path = /usr/bin/java

(String) The Java absolute path.

iSCSI configuration example

default_volume_type = IFT-ISCSI
enabled_backends = IFT-ISCSI

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

Fibre Channel configuration example

default_volume_type = IFT-FC
enabled_backends = 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
infortrend_slots_a_channels_id = 4,5

Multipath configuration

  • Enable multipath for image transfer in /etc/cinder/cinder.conf for each back end or in [backend_defaults] section as a common configuration for all backends.

    use_multipath_for_image_xfer = True

    Restart the cinder-volume service.

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

    volume_use_multipath = True

    Restart the nova-compute service.

Extra spec usage

  • 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
