PSSeriesISCSIDriver
-------------------
* Version: 1.4.1
* volume_driver=cinder.volume.drivers.dell_emc.ps.PSSeriesISCSIDriver
* CI info: https://wiki.openstack.org/wiki/ThirdPartySystems/Dell_Storage_CI
* Description:
    Implements commands for Dell EMC PS Series ISCSI management.
    
        To enable the driver add the following line to the cinder configuration:
            volume_driver=cinder.volume.drivers.dell_emc.ps.PSSeriesISCSIDriver
    
        Driver's prerequisites are:
            - a separate volume group set up and running on the SAN
            - SSH access to the SAN
            - a special user must be created which must be able to
                - create/delete volumes and snapshots;
                - clone snapshots into volumes;
                - modify volume access records;
    
        The access credentials to the SAN are provided by means of the following
        flags:
    
        .. code-block:: ini
    
            san_ip=<ip_address>
            san_login=<user name>
            san_password=<user password>
            san_private_key=<file containing SSH private key>
    
        Thin provision of volumes is enabled by default, to disable it use:
    
        .. code-block:: ini
    
            san_thin_provision=false
    
        In order to use target CHAP authentication (which is disabled by default)
        SAN administrator must create a local CHAP user and specify the following
        flags for the driver:
    
        .. code-block:: ini
    
            use_chap_auth=True
            chap_login=<chap_login>
            chap_password=<chap_password>
    
        eqlx_group_name parameter actually represents the CLI prompt message
        without '>' ending. E.g. if prompt looks like 'group-0>', then the
        parameter must be set to 'group-0'
    
        Version history:
    
        .. code-block:: none
    
            1.0   - Initial driver

        Volumes are stored as files on the mounted Quobyte volume. The hypervisor
        will expose them as block devices.
    
        Unlike other similar drivers, this driver uses exactly one Quobyte volume
        because Quobyte USP is a distributed storage system. To add or remove
        capacity, administrators can add or remove storage servers to/from the
        volume.
    
        For different types of volumes e.g., SSD vs. rotating disks,
        use multiple backends in Cinder.
    
        Note: To be compliant with the inherited RemoteFSSnapDriver, Quobyte
              volumes are also referred to as shares.
