Enable the HP LeftHand/StoreVirtual iSCSI driver in legacy mode

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.

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
                    

Save the changes to the cinder.conf file and restart the cinder-volume service.

Configure CHAP on each of the nova-compute nodes.

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.
