Interpretation:

You are using the disk c12t15d3 to 100% capacity. This may be causing an i/o bottleneck.

Your transfer rates and wait times are probably pretty rough too.

Some scripts for overall performance issues are attached.

The first thing you should do is download/install the latest sar cumulative patch. Since you didn't bother to report your OS, I won't bother to identify the patches but there were fixes for sar -d output under 11.x.
