Share same iscsi lun

Hello everyone, I have 3 proxmox in a cluster and I need to share the same lun among the 3 of them, I was able to register the same lun on the 3 proxmox and also able to create a LVM from the iscsi and the 3 proxmox are seeing this LVM.

Now the problem is that only PROXMOX-1 is able connect to the iscsi target, the other two are connecting and disconnecting with the following log errors. Is there any way I can accomplish this, I really need to use HA.

PROXMOX-2
