Fujitsu ETERNUS DX driver

Fujitsu ETERNUS DX driver provides FC and iSCSI support for ETERNUS DX S3 series.

The driver performs volume operations by communicating with ETERNUS DX. It uses a CIM client in Python called PyWBEM to perform CIM operations over HTTP.

You can specify RAID Group and Thin Provisioning Pool (TPP) in ETERNUS DX as a storage pool.

System requirements

Supported storages:

  • ETERNUS DX60 S3

  • ETERNUS DX100 S3/DX200 S3

  • ETERNUS DX500 S3/DX600 S3

  • ETERNUS DX8700 S3/DX8900 S3

  • ETERNUS DX200F

Requirements:

  • Firmware version V10L30 or later is required.

  • The multipath environment with ETERNUS Multipath Driver is unsupported.

  • An Advanced Copy Feature license is required to create a snapshot and a clone.

Supported operations

  • Create, delete, attach, and detach 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. (*1)

  • Get volume statistics.

(*1): It is executable only when you use TPP as a storage pool.

Preparation

Package installation

Install the python-pywbem package for your distribution.

ETERNUS DX setup

Perform the following steps using ETERNUS Web GUI or ETERNUS CLI.

Note

  • These following operations require an account that has the Admin role.

  • For detailed operations, refer to ETERNUS Web GUI User’s Guide or ETERNUS CLI User’s Guide for ETERNUS DX S3 series.

  1. Create an account for communication with cinder controller.

  2. Enable the SMI-S of ETERNUS DX.

  3. Register an Advanced Copy Feature license and configure copy table size.

  4. Create a storage pool for volumes.

  5. (Optional) If you want to create snapshots on a different storage pool for volumes, create a storage pool for snapshots.

  6. Create Snap Data Pool Volume (SDPV) to enable Snap Data Pool (SDP) for create a snapshot.

  7. Configure storage ports used for OpenStack.

    • Set those storage ports to CA mode.

    • Enable the host-affinity settings of those storage ports.

      (ETERNUS CLI command for enabling host-affinity settings):

      CLI> set fc-parameters -host-affinity enable -port <CM#><CA#><Port#>
CLI> set iscsi-parameters -host-affinity enable -port <CM#><CA#><Port#>

  8. Ensure LAN connection between cinder controller and MNT port of ETERNUS DX and SAN connection between Compute nodes and CA ports of ETERNUS DX.

Configuration

  1. Add the following entries to /etc/cinder/cinder.conf:

    FC entries:

    volume_driver = cinder.volume.drivers.fujitsu.eternus_dx.eternus_dx_fc.FJDXFCDriver
cinder_eternus_config_file = /etc/cinder/eternus_dx.xml

    iSCSI entries:

    volume_driver = cinder.volume.drivers.fujitsu.eternus_dx.eternus_dx_iscsi.FJDXISCSIDriver
cinder_eternus_config_file = /etc/cinder/eternus_dx.xml

    If there is no description about cinder_eternus_config_file, then the parameter is set to default value /etc/cinder/cinder_fujitsu_eternus_dx.xml.

  2. Create a driver configuration file.

    Create a driver configuration file in the file path specified as cinder_eternus_config_file in cinder.conf, and add parameters to the file as below:

    FC configuration:

    <?xml version='1.0' encoding='UTF-8'?>
<FUJITSU>
<EternusIP>0.0.0.0</EternusIP>
<EternusPort>5988</EternusPort>
<EternusUser>smisuser</EternusUser>
<EternusPassword>smispassword</EternusPassword>
<EternusPool>raid5_0001</EternusPool>
<EternusPool>tpp_0001</EternusPool>
<EternusPool>raid_0002</EternusPool>
<EternusSnapPool>raid5_0001</EternusSnapPool>
</FUJITSU>

    iSCSI configuration:

    <?xml version='1.0' encoding='UTF-8'?>
<FUJITSU>
<EternusIP>0.0.0.0</EternusIP>
<EternusPort>5988</EternusPort>
<EternusUser>smisuser</EternusUser>
<EternusPassword>smispassword</EternusPassword>
<EternusPool>raid5_0001</EternusPool>
<EternusPool>tpp_0001</EternusPool>
<EternusPool>raid_0002</EternusPool>
<EternusSnapPool>raid5_0001</EternusSnapPool>
<EternusISCSIIP>1.1.1.1</EternusISCSIIP>
<EternusISCSIIP>1.1.1.2</EternusISCSIIP>
<EternusISCSIIP>1.1.1.3</EternusISCSIIP>
<EternusISCSIIP>1.1.1.4</EternusISCSIIP>
</FUJITSU>

    Where:

    EternusIP

    IP address for the SMI-S connection of the ETRENUS DX.

    Enter the IP address of MNT port of the ETERNUS DX.

    EternusPort

    Port number for the SMI-S connection port of the ETERNUS DX.

    EternusUser

    User name for the SMI-S connection of the ETERNUS DX.

    EternusPassword

    Password for the SMI-S connection of the ETERNUS DX.

    EternusPool (Multiple setting allowed)

    Storage pool name for volumes.

    Enter RAID Group name or TPP name in the ETERNUS DX.

    EternusSnapPool

    Storage pool name for snapshots.

    Enter RAID Group name in the ETERNUS DX.

    EternusISCSIIP (Multiple setting allowed)

    iSCSI connection IP address of the ETERNUS DX.

    Note

    • For EternusSnapPool, you can specify only RAID Group name and cannot specify TPP name.

    • You can specify the same RAID Group name for EternusPool and EternusSnapPool if you create volumes and snapshots on a same storage pool.

    • For EternusPool, when multiple pools are specified, cinder-scheduler will select one from multiple pools to create the volume.

Configuration example

  1. Edit cinder.conf:

    [DEFAULT]
enabled_backends = DXFC, DXISCSI

[DXFC]
volume_driver = cinder.volume.drivers.fujitsu.eternus_dx.eternus_dx_fc.FJDXFCDriver
cinder_eternus_config_file = /etc/cinder/fc.xml
volume_backend_name = FC

[DXISCSI]
volume_driver = cinder.volume.drivers.fujitsu.eternus_dx.eternus_dx_iscsi.FJDXISCSIDriver
cinder_eternus_config_file = /etc/cinder/iscsi.xml
volume_backend_name = ISCSI

  2. Create the driver configuration files fc.xml and iscsi.xml.

  3. Create a volume type and set extra specs to the type:

    $ openstack volume type create DX_FC
$ openstack volume type set --property volume_backend_name=FC DX_FX
$ openstack volume type create DX_ISCSI
$ openstack volume type set --property volume_backend_name=ISCSI DX_ISCSI

    By issuing these commands, the volume type DX_FC is associated with the FC, and the type DX_ISCSI is associated with the ISCSI.
