No, standalone.

No, DKA100 and DKA300 are localdisks.
Maybe DKA200: and DKA400: were external, but by now they aren't here anymore ;)

Yes, I cut the not relevant part of the command ...

Hmmm... I don't think they've gone fishing :)
Someone removed them.
They couldn't be internal, since the second disk (DKA300 has been put under
the PSU and cables show that no other internal devices were connected...)

Why ? I thought so..
