Something kinda weird happened to me recently: my hard disks (one
swap, one system) boot fine and operate fine (that I can see) but when
I do a "scsimodes /dev/sd0a", "scsimodes /dev/sd1a" or use the "disk"
program to get info about the make, model and other info about the
drives, they come back with "<commandname>: bad ioctrl" (I'm not at
the NeXT in question now, so the spelling might not be exact, sorry).

The disk labels can't even be accessed, but they can be during boot
because that is how the system knows that the 105MB labeled "swapdisk"
should be used for swap and tmp space.

What would cause the label for a disk to only be visible during boot
but at all other times (using the scsimodes command) the info comes back
with 0 cylinders, 0 sectors, 1023 bytes/sector, couldn't get label name,
couldn't get drive make (QUANTUM or IMPRIMIS or something should come
back here, normally).

Thanks for any help you can offer.
