DFS replication and lost ISCSI connections

hello

we having pretty serious issue 2 of our 2008r2 server. these servers being used citrix provisioning services streams our xen app servers.

the configuration of server pretty basic, 6 nics, dual proc/quad core , 32g or ram. 4 of nics intel , bounded lacp channel, 2 other nics used iscsi traffic. 2 storage nics not bonded , have dell eql hit kit tools installed , configured on each host.

the issue having pretty strange, once enable dfs replication, after few hours, replication partner loose connections storage array. when @ iscsi control panel, target in status of reconnecting.

　

the strange thing when use route print, can see route storage array correct. however, when i  perform trace route, server trying route iscsi traffic via lan network. i've tried created more specific static routes ip's of array without success.

to reconnect storage, i've had disable/enable storage nics or reboot host.

any assistance on matter great.

thanks
