 Enable the HP LeftHand/StoreVirtual iSCSI driver in legacy mode

The HPLeftHandISCSIDriver is installed with the OpenStack software.

  1. If you are not using an existing cluster, create a cluster on the HP Lefthand storage system to be used as the cluster for creating volumes.

  2. Make the following changes in the /etc/cinder/cinder.conf file.

    ## REQUIRED SETTINGS
    
    # VIP of your Virtual Storage Appliance (VSA).
    san_ip=10.10.0.141
    
    # LeftHand Super user username
    san_login=lhuser
    
    # LeftHand Super user password
    san_password=lhpass
    
    # LeftHand ssh port, the default for the VSA is usually 16022.
    san_ssh_port=16022
    
    # LeftHand cluster to use for volume creation
    san_clustername=ClusterLefthand
    
    # LeftHand iSCSI driver
    volume_driver=cinder.volume.drivers.san.hp.hp_lefthand_iscsi.HPLeftHandISCSIDriver
    
    ## OPTIONAL SETTINGS
    
    # LeftHand provisioning, to disable thin provisioning, set to
    # set to False.
    san_thin_provision=True
    
    # Typically, this parameter is set to False, for this driver.
    # To configure the CLIQ commands to run locally instead of over ssh,
    # set this parameter to True
    san_is_local=False
                        
  3. Save the changes to the cinder.conf file and restart the cinder-volume service.

The HP LeftHand/StoreVirtual driver is now enabled in legacy mode on your OpenStack system. If you experience problems, review the Block Storage service log files for errors.

To configure the VSA

  1. Configure CHAP on each of the nova-compute nodes.

  2. Add server associations on the VSA with the associated CHAPS and initiator information. The name should correspond to the hostname of the nova-compute node. For Xen, this is the hypervisor host name. To do this, use either CLIQ or the Centralized Management Console.
