Veritas ACCESS iSCSI driver

Veritas Access is a software-defined scale-out network-attached storage (NAS) solution for unstructured data that works on commodity hardware and takes advantage of placing data on premise or in the cloud based on intelligent policies. Through Veritas Access iSCSI Driver, OpenStack Block Storage can use Veritas Access backend as a block storage resource. The driver enables you to create iSCSI volumes that an OpenStack Block Storage server can allocate to any virtual machine running on a compute host.

Requirements

The Veritas ACCESS iSCSI Driver, version 1.0.0 and later, supports Veritas ACCESS release 7.4 and later.

Supported operations

• Create and delete volumes.

• Create and delete snapshots.

• Create volume from snapshot.

• Extend a volume.

• Attach and detach volumes.

• Clone volumes.

Configuration

1. Enable RESTful service on the Veritas Access Backend.

2. Create Veritas Access iSCSI target, add store and portal IP to it.

   You can create target and add portal IP, store to it as follows:

   Target> iscsi target create iqn.2018-02.com.veritas:target02
   Target> iscsi target store add target_fs iqn.2018-02.com.veritas:target02
   Target> iscsi target portal add iqn.2018-02.com.veritas:target02 10.10.10.1
   ...
   

   You can add authentication to target as follows:

   Target> iscsi target auth incominguser add iqn.2018-02.com.veritas:target02 user1
   ...
   

3. Ensure that the Veritas Access iSCSI target service is online. If the Veritas Access iSCSI target service is not online, enable the service by using the CLI or REST API.

   Target> iscsi service start
   Target> iscsi service status
   ...
   

   Define the following required properties in the cinder.conf file:

   volume_driver = cinder.volume.drivers.veritas_access.veritas_iscsi.ACCESSIscsiDriver
   san_ip = va_console_ip
   san_api_port = 14161
   san_login = master
   san_password = password
   target_port = 3260
   vrts_lun_sparse = True
   vrts_target_config = /etc/cinder/vrts_target.xml
   

4. Define Veritas Access Target details in /etc/cinder/vrts_target.xml:

   <?xml version="1.0" ?>
   <VRTS>
        <VrtsTargets>
             <Target>
                     <Name>iqn.2018-02.com.veritas:target02</Name>
                     <PortalIP>10.10.10.1</PortalIP>
                     <Authentication>0</Authentication>
             </Target>
        </VrtsTargets>
   </VRTS>
   ...
