Hmmm. Still no luck.
For example, I'm trying:
define file name=c3t50060E80047F0B02d3s4, path=/dev/rdsk
define process name=randWriteProcess,instances=$nprocs
{
thread name=randWriteThread1, memsize=16m, instances=$nthreads
{
flowop write name=randWriter1, filename=c3t50060E80047F0B02d3s4,
iosize=$iosize, random, workingset=$workingset, directio=$directio, dsync=$dsync
}
}
Ultimately, I'm trying to test against a raw vxvm volume, but that didn't work,
so I tried the DMP device and finally just one of the c-t-d-s devices, with no
joy. I can dd to and from the device, but filebench says:

...Demetri
P.S. Yes, by all means, I'm being tip-toe careful, especially with
data-scribbly stuff. Being the somewhat paranoid type, I change the device or
directory ownership and do the testing as my own uid (and this keeps filebench
from removing my special files and replacing them with directories!)
