[PVE-User] FC-Luns only local devices?

[Hermann]

Dear PVE-USers,

I would really appreciate being steered in the right direction as to the
connection of Fibre-Channel-Luns in Proxmox.

As far as I can see, FC-LUNs only appear als local blockdevices in PVE.
If I have several LWL-Cables between my Cluster and these bloody
expensive Storages, do I have to set up multipath manually in debian?

Or is there a CLI-command handling all this?

Any helping hint is heartily appreciated.

Greetings, Hermann
