My guess for the first case (vpath1a) is that the IBM driver is not
correctly implementing the necessary DDI properties for ZFS to determine
the configuration of the device. What bits are you using? Off the top
of my head, this should catch the most likely candidate:
# dtrace -n ldi_get_size:return'{trace(arg1)}'
I'd also check to see if there are any updates from IBM. From the looks
of it, 'vpath1c' cannot even be opened from userland, so something else
seems misconfigured in that case.
