iSCSI issues

I am currently testing ProxMox to replace our VMWare cluster.
We have a Promise Vess R3600xiD installed. it is an iSCSI device.

This device supports multipath. It has 2 redundant controllers, each with 4 LACP ports in LACP trunk.
Controller 1 LACP trunk: 10.0.10.11
Controller 1 LACP trunk: 10.0.10.12

I am able to see the iSCSI when i add portal 10.0.10.11 or 10.0.10.12
It will find the "target", and show me the name.
I can add this iSCSI.

Then, I try to create an LVM.
It keeps giving me this error:
“create storage failed: error during cfs-locked 'file-storage_cfg' operation: pvcreate '/dev/disk/by-id/scsi-22217000155f36637' error: Cannot use device /dev/disk/by-id/scsi-22217000155f36637 with duplicates. (500)"

I figured, it might be related to multipath.
So, I followed these guidelines:
https://pve.proxmox.com/wiki/ISCSI_Multipath

strangely enough, all steps work except "multipath -ll", which gave zero/NULL results.

Still, I was able to add/remove the iSCSI device. Every time I entered the portal IP, it would show the target name.


Anyone any idea what I am doing wrong here?
