Does anyone know why dt_vdevices() creates a vscsi node on legacy iseries?
I'm sure only viodasd and viocd is required as blockdevice type.

Because the IBM vscsi client (in theory) works on legacy iSeries.

I'm asking because there are many unneeded nodes.
Have you tried to create only the nodes for disks/cds that are really
present and modify viodasd to use only device-tree data?

I'll have a look, but that would require interacting with the hypervisor
very early in the boot sequence ...
