Title:
Nova-compute connects to all of the iscsi target
Status in OpenStack Compute (nova):
Incomplete
Status in os-brick:
In Progress
Bug description:
Nova-compute tries to connect to all of the iscsi target which discovered
when using multhpath in Kilo.
As a result , a lot of unnecessary iscsi sessions occur on the nova-compute.
We have to choose correct targets from output of iscsiadm discovery by
iscsi_properties of the volume we try to connect.
Steps of attaching multipath device is like this:
1. discover iscsi targets
2. get all active iscsi sessions
3. compare 1. with 2. and connect to all iscsi targets not connected
It should be like this:
1. discover iscsi targets
2. choose correct targets from output of discovery
3. get all active iscsi sessions
4. compare 2. with 3. and connect to the iscsi target if it is not connected
