how to identified this iostat value

Hi All AIX expert
i'm using AIX 5.2
When i execute this command which is :

----------------------------------------------------------------------
>> iostat -a

System configuration: lcpu=4 disk=30

tty: tin tout avg-cpu: % user % sys % idle % iowait
0.1 7.9 80.6 2.0 17.1 0.4
" Disk history since boot not available. "

----------------------------------------------------------------------

In linux, if the % idle is below 20%, then the explanation is "If '%idle' goes below 20%, the system maybe queuing up disk I/Os and response time suffers."

But i'm not sure with AIX, what does that % idle represent and the rest such as % user and % iowait....

When i have above read, does that mean my disk I/O in a danger situation??
