Re: Configure multiple initiator zoning to single initiator zoning
Welcome to communities! If the hosts are able to see the same LUNs and paths after zone re-config, then everything should be OK. They will see the same datastores and content.If your FC switch does not...

Currently it looks like you have iSCSI ports on 4 subnets.The keywords here are "routing is not supported with port binding".By "same broadcast domain" here we mean that all bound vmk ports and all...

Thanks for the reply, Dell initially set up SAN using the this configuration. I think you're right in that the all ports are advertised but the ESXi won't be able to access them. What are my options...

first of all iscsi dont need any separate vlans for each iscsi target ports, that is a single vlan is enough.Here you have total 8 ports in the iscsi storage side, and you need to have 8 pnics and 8...

Can this be resolved by only using Static Discovery rather than Dynamic, so the unreachable iSCSI targets are not listed? That would reduce the number of targets from 8 to 4 that the host is aware of,...

In effect it would look like this: ESXi host:vSwitch1vmk1 IP: 192.168.132.105 (Port Binding vmnic 1)vmk2 IP: 192.168.132.106 (Port Binding vmnic 2)Storage array:Controller...

Yes, static discovery could do the trick. But still, if you're doing port binding then all vmkernel ports used by SW iSCSI initiator need to be on same subnet which leaves you on using single port per...

if you have iscsi offload try to use them, also check the performance of the software and hardware initiators.
