Yes, several differences.  Adding and removing simple SCSI devices has turned
out to be easy enough in Linux.  The complexities of multipathing software and
volume management tools makes removing devices more difficult, but Linux isn't
the only one that suffers from that.

Take note that one thing I do miss in Linux is that the iostat command does not 
have
the ability to show tape devices and their utilization which I find very useful
in the world of NBU.  If the tape device is fibre channel, then you can get
some of that depending on the HBA model and the driver version and if its
through a switch, you can get it from there as well.  Still not the same.

Thanks
Peter
