wait I/O

Hi,

I'm collecting cpu statistics with the table() interface.
In the tbl_sysinfo structure, there is a variable accumulating
wait time. My understanding is that it's cpu idle time
with I/O pending. Is that correct ?

I've noticed that this wait time seems to reflect disk I/O
through the raw devices and not through the file system(ufs
or advfs). I've not observed that on other OS (Solaris or AIX).
Why would that be the case?

Thanks,
