ISCSI question on ME4024

Hello and thank you for you insights,

I have a PVE cluster and i want the volumes on ME4024 to be handled by multipathing on the cluster.

I configured my controllers like this :

 

And configured 2 SAN switches with 2 separate non routed private vlan as suggested by Vendors.

On PVE i declared the 8 controllers ip as ISCSI Portals.

 

 

And then when i map a volume on all my 3 initiators and use multipath i have theses errors :

iscsid: Kernel reported iSCSI connection 1:0 error (1022 - ISCSI_ERR_NOP_TIMEDOUT: A NOP has timed out) state (3)
Feb 28 14:11:20 pve3 kernel: [ 543.556114] connection6:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4295025408, last ping 4295026688, now 4295027968

Feb 28 14:11:23 pve3 pmxcfs[1709]: [confdb] crit: cmap_initialize failed: 2

 

I've seen somewhere that it occurs because multiple hosts are using the same iscsi initiator name.

So why can't i declare each controller with different iqn and do you think it's the problem i'm facing?

 

 

Thanks a lot.
