Thanks kermit on the reply. Appreciate your help! I will try to re-configure single initiator zoning tomorrow.
I would probably prefer to unmount the datastore first, re-configure zoning and mount back the datastore without any fuss. But I might worry about the content of the datastore once I mount the datastore back. Will it cause any effect if the LUN presented to the ESXi host has a different path after i re-configure zoning? But how about the other server which I have yet to re-configure the zone. Would it cause any downtime on the datastore? or not able to see the datastore due to different path. Currently, I have 8 paths to each LUNs ( total 2 LUNs ). After single-initiator configuration, correct me if im wrong, I will have 4 paths on each LUNs, ( 2 HBA on each server and 2 targets on each nodes. I have total of 2 nodes and 2 esxi servers )
I'm still pretty new on shared storage and zoning. Still learning here.
