two answers:

1.) Think of: It could happen, instead of it shouldn't happen :-)
2.) Adding a new JBOD on the fly, without reboot the whole machine, what
I've done under Solaris and Linux and that wasn't a big deal. It just
works.

At the moment, replug the SAS cable let you see not all the same disks,
like before. Means, replug several times, you get different disks, but
most the last 30~46 are missed.

However: SAS is a hot pluggable "bus", so it should work, but it
doesn't. Maybe a bug in the driver or something else.
