The mrsasutil command does work (see the first attachment where the output of
"show volumes" is interspersed with the kernel messages).

Apparently mrsasutil is issuing a request which maps to something either the
driver or controller doesn't like, which triggers the kernel messages.

It may be interesting to note that the output of "mrsasutil show volumes"
triggers one "mrsas0: IOCTL command 0xc1045166 is not handled" kernel message
and then four "There is no Controller number X" kernel messages, while the
truss output (in the second attachment) shows all five returning "ERR#2 'No
such file or directory'" to mrsasutil. Despite these error returns, mrsasutil
is displaying the correct information about the volumes. If you weren't
watching the console, looking in the message buffer or reading the nightly
periodic reports, you'd never know anything was wrong.
