the man page contains:
If more than 4 disk drives are configured in the system,
iostat displays only the first 4 drives, with priority given
to Massbus disk drives (i.e. if both Unibus and Massbus
drives are present and the total number of drives exceeds 4,
then some number of Unibus drives will not be displayed in
favor of the Massbus drives). To force iostat to display
specific drives, their names may be supplied on the command
line.
this is wrong conceptually as we have neither
unibus nor massbuss here in rt-land, and further
it lies in that iostat always displays four disks,
even if three of them are fictions. on top of that,
requesting nonsense defaults to the normal display,
to whit:
e40-342f-2% iostat ra0
tty hd0 dk1 dk2 dk3 cpu
tin tout bps tps msps bps tps msps bps tps msps bps tps msps us ni sy id
0 4 3 0 60.1 0 0 0.0 0 0 0.0 0 0 0.0 0 0 3 96
also, everytime, and i mean every time, that is
what is displayed for hd0 (0 transactions per
second, and 60.1 milliseconds per seek).
now let me tell you that i am recursively diffing
an nfs filesystem against an afs filesystem, and
my disk drive is rattling away at a substantially
significant rate (roughly like the telephone ringing
off the hook), so tps==0 is absurd.
something wrong here.
