Veritas Access Administrator's Guide

To copy a Cinder driver from Veritas Access to an OpenStack Cinder node

1. Browse to the location of the Cinder driver on Veritas Access:

   /opt/VRTSnas/pysnas/openstack/

2. Copy the complete veritas_access directory from the driver location on Veritas Access to the Cinder node:

   /usr/lib/python2.7/site-packages/cinder/volume/drivers/

To create a new backend volume called ACCESS_ISCSI in OpenStack Cinder

1. Add the following configurations in the /etc/cinder/cinder.conf file on your OpenStack controller node.

   enabled_backends= va-iscsi
   [va-iscsi] 
   volume_driver = cinder.volume.drivers.veritas_access.veritas_iscsi.ACCESSIscsiDriver
   volume_backend_name = ACCESS_ISCSI
   iscsi_protocol = iscsi
   reserved_percentage = 0
   vrts_iscsi_port = 3260
   vrts_lun_sparse = false
   vrts_target_config = /etc/cinder/vrts_target.xml
   vrts_server_ip = 10.182.168.90
   vrts_port = 14161
   vrts_user = <master_user>
   

   You can obtain the configuration details for adding to the /etc/cinder/cinder.conf file by executing the following command:

   Openstack> cinder iscsi configure <target_list>

   Note:

   To create a sparse LUN, you need to set the vrts_lun_sparse option to true.

2. Append the following to the /etc/cinder/vrts_target.xml file on your OpenStack controller node:

   <?xml version="1.0" ?>
                     <VRTS>
                         <VrtsTargets>
                              <Target>
                                  <Name>iqn.2018-02.com.veritas:target02
                                  <PortalIP>10.182.174.189
                                  <Authentication>0
                              </Target>
                          </VrtsTargets>
                     </VRTS>
   

   If authentication is used for the target, the user name and password should to be mentioned in the /etc/cinder/ vrts_target.xml file.

   Example:

   <?xml version="1.0" ?>
                     <VRTS>
                        <VrtsTargets>
                             <Target>
                                 <Name>iqn.2018-02.com.veritas:target02
                                 <PortalIP>10.182.174.189
                                 <Authentication>1
                                 <Auth_username>user1
                                 <Auth_password>user123
                             </Target>
                        </VrtsTargets>
                     </VRTS>
   

   Note:

   Make sure that every target added to the /etc/cinder/vrts_target.xml file is in the online state in Veritas Access.

3. Restart the Cinder volume and Cinder scheduler services by using the following commands:

   service openstack-cinder-volume restart
   service openstack-cinder-scheduler restart
   

4. On the OpenStack controller node, create a volume type such as vrts_vol_type.

   This volume type is used to link to the volume backend.

   [root@openstack01 ~(keystone_admin)]# cinder type-create vrts_vol_type
   +--------------------------------------+------------------+ 
   | ID                                   | Name             | 
   +--------------------------------------+------------------| 
   | d854a6ad-63bd-42fa-8458-a1a4fadd04b7 | vrts_vol_type    |
   +--------------------------------------+------------------+
   

5. Link the volume type with the ACCESS_ISCSI back-end.

   [root@openstack01 ~(keystone_admin)]# cinder type-key vrts_vol_type set 
   volume_backend_name= ACCESS_ISCSI
   [root@openstack01 ~(keystone_admin)]# cinder create --volume-type vrts_vol_type 
   --display-name vol1 1

   Note:

   You can create individual volumes by using the following command: cinder create --volume-type vrts_vol_type --display-name vol1 --metadata dense=True 2

6. Extend the volume to 2 GB.

   [root@openstack01 ~(keystone_admin)]# cinder extend vol1 2
   [root@openstack01 ~(keystone_admin)]#
   [root@openstack01 ~(keystone_admin)]# cinder list

   +-----------------------+-----------+------+------+---------------+----------+-------------+
   [root@openstack01 ~(keystone_admin)]#
   

7. Create a snapshot.

   [root@openstack01 ~(keystone_admin)]# cinder list
