Hello dm-devel-
I'm working with the multipathing package and a DDN 8500. I've been able to
successfully configure failover and failback. The system is configured as
such:
qla_port_1 ---- ctrl A port 4 ---- LUN 3 (LUN 7)
qla_port_2 ---- ctrl B port 4 ---- LUN 7 (LUN 3)
Where LUN 3 is on a dedicated port to qla_port_1 and qla_port_2 is dedicated to LUN 7.
The problem that I'm having is all the traffic is going through qla_port_1,
qla_port_2 appears to be sitting idle until a failover.
To compensate, I've been using dmsetup to force the qla_port_2 ---- LUN 7
path.
Is there a better way than using dmsetup to do this? multipath isn't an
option, as it negatively impacts performance.
Thanks-
-Mike
