Hello ,

I've several iscsi lun replication sessions on ns40. Yesterday , i deleted some of them . After deleted iscsi replication session esx 4 hosts lost their iscsi datastore connectivity. The esx host   generated the following errors "Lost connectivity to storage device naa ,  " . After 5-6 sec it's repaired  the datastore connectivity . I think celerra closed the iscsi session when the replication session deleted.I need to determine what is causing this problem

esxhost:

4 uplink port for iscsi network (static link aggregation  configured)

multiple iscsi target on the celerra .

celerra :

configured lacp ( 4 port)

Thank you.
