Subj:   sar -d stats
 
From:   Ferry, Craig

When I look at sar -d stats, should I expect to see an even distribution across my disks? The following is what mine look like (for today). I am trying to figure out why I am seeing high wait i/o on my system.


Average  /dev/rdsk/c0t0d0s0          0   1.000       0       0     0.0  0.2
