Hi, I set my openstack volume driver to NetAppISCSIDriver.
(nova version is essex milestone-1, I think it's too old, but It's not important)
I also configured some flags for driver.
This is my configuration.(nova.conf)
42 ### volume configuration
43 --volume_manager=nova.volume.manager.VolumeManager
45 --volume_driver=nova.volume.netapp.NetAppISCSIDriver
46 --netapp_login=administrator
47 --netapp_password=password
48 --netapp_server_hostname=10.4.1.252
49 --netapp_server_port=8088
50 --netapp_storage_service=Cloud
52 --netapp_wsdl_url=http://10.4.1.252/dfm.wsdl
53 --netapp_storage_service_prefix=cloud-
When I create volume It looks like normal.
~$ nova volume-create 5 --display_name jaesang3 --availability_zone b_zone
~$ nova volume-list
+----+-----------+-----------------+------+--------------------------------------+
| ID | Status | Display Name | Size | Attached to |
+----+-----------+-----------------+------+--------------------------------------+
| 35 | available | jaesang3 | 5 | None |
+----+-----------+-----------------+------+--------------------------------------+
It's value of volumes table.

But When I attach volume to VM, It looks like abnormal.
This is my block_device_mapping db table.

You can see volume_id is different. BUT every device_path is same. So when I mount a volume in VM, wrong volume mounted.
When I use HP san volume driver, every device_path is different. for example,
mysql> select id,instance_id,volume_id,connection_info from block_device_mapping where deleted=0 limit 3\G

Why Netapp driver set device_path is same? Is this normal situation?
Please help me in understanding setup using netapp driver.
Thanks in advance.
