Re: iscsi multipath fails when cluster service is started

No, I use dedicated subnets for the heartbeat, public, and iscsi connections.
The addresses are:

10.10.5.11 / 255.255.255.0 heartbeat
10.10.1.31 / 255.255.255.0 iscsi 1
10.10.1.32 / 255.255.255.0 iscsi 2
192.168.0.81 / 255.255.0.0 public

Sorry if I missed this previously, are your iSCSI network connections on the
same subnet as your public network interface? If so, then I could see the
behavior you're describing ocurring. This would be described in
http://support.microsoft.com/kb/175767

If the iSCSI connections are not on the same subnet as your other cluster
networks, they shouldn't affect these connections when pulled.

i'm already in contact with the storage/server/network/iscsi vendor. it's
dell.
but it seems to be a simple windows problem.

i've configured a virutal machine with windows server 2003 under esx4 to
test the behavior of the network inferfaces.
both interfaces are in the same subnet with no gateway.
i've started a ping to a reachable host. when i disable the network
connection of the vm, i only got 2 timeouts and then it goes on.

when i do the same procedure on my physical server with installed cluster
services, the ping stops and the host is isolated even though the second
interface still has a connection.
is this a common behavior under windows server 2003 enterprise x64 with
cluster service?
i think the problem is that the interfaces are in the same subnet.
there is only one of two interfaces in the cluster administrator under
"networks" and the missing interfaces causes the problem.
