multipath conf for boot from SAN

[mcarpendale]

Hi, Ive got a Cisco UCS-X bare-metal server that I'd like to use as a worker node

Its Boot from SAN.

The boot volume is below, showing as sde, f, g, h due to lack of multi-path config

mcarpendale@mcarpendale--Mac15 talos % talosctl get disks --insecure -n $WORKER_NODE_IP

mcarpendale@mcarpendale--Mac15 talos % 

How does one handle this on the initial boot from ISO? I'm trying the below - but being new to Talso I'm winging it.......

customization:
    extraKernelArgs:
        - talos.platform=metal
        - rd.multipath=default
        - multipath=on
        - root=/dev/mapper/mpatha
        - multipath.wwid=624a93703bc12bfc226b41c3009e4ff2
    systemExtensions:
        officialExtensions:
            - siderolabs/nvme-cli

Thanks

Hi @mcarpendale, I'm tackling the same issue myself, did you ever find a solution?
