We have a test cluster setup with MPIO and all seems to be working well.
The setup is using Windows Server 2012 r2 with a qnap as the backend storage.
Routes are as follows;
172.16.10.10 (qnap port 1)
172.17.10.10 (qnap port 2)
Traffic flows perfectly over each switch with the failover link using MPIO working fine.
The issue we are facing is whenever we disconnect our first link to the qnap to tesy the failover (port 1) the other link kicks in fine however when we restore the 172.16.10.10 link it doesn't automatically map the iSCSI target. So if link 2 (port 2) was to fail the entire cluster fails until we either reconnect the iSCSI target manually or we reboot the server.
My impression is that when a link goes down the other kicks in and once the first link is repaired it should automatically reconnect to the target?
Is there an automatic reconnect setting I'm missing?
