This flow is problematic,
- it will add more command sent to XMS.
- not sure what will happen if the last IG volumes terminates the connection and at the same time a new connection get's initialized.

I agree, but if we want to delete the initiator group, there is no other way but send the request to XMS.
It is not an error issue but how XtremIO driver should work.
By the way other storage vendor working like this, this is why I think that we should also work as so. Users maybe use multiple backend storage and keep all the storage have the same work will be friendly to user.
