VMware: "Storage error: Unable to find iSCSI Target"

[Ryan Hsu]

The following Tempest tests are failing with the VMware nova driver:

tempest.api.compute.servers.test_delete_server.DeleteServersTestJSON.test_delete_server_while_in_attached_volume
tempest.api.compute.servers.test_delete_server.DeleteServersTestXML.test_delete_server_while_in_attached_volume
tempest.api.compute.servers.test_server_rescue_negative.ServerRescueNegativeTestJSON.test_rescued_vm_detach_volume
tempest.api.compute.servers.test_server_rescue_negative.ServerRescueNegativeTestXML.test_rescued_vm_detach_volume

The following error is seen in the logs:

do you have iSCSI in the tempest env?

Is this related? https://review.openstack.org/#/c/144600/

I hit the same issue and it was due to the way in which cinder was configured. My understanding is that this is the case here as this is the CI. Since updating the config is up and running.
