If you run iostat with the "X" option, you can get stats per port:
$ iostat -zxMX 5
ssd7 0.4 117.5 0.0 13.4 0.0 0.6 4.7 0 22
ssd7.fp2 0.2 58.4 0.0 6.7 0.0 0.0 0.0 0 0
ssd7.fp4 0.2 59.0 0.0 6.7 0.0 0.0 0.0 0 0

If you want the WWPN displayed in the output, you can add
the "n" option:
$ iostat -zxnMX 5
0.0 122.5 0.0 15.3 0.0 0.5 0.0 3.9 0 22
c2t60060160BE120F0019092094574FDC11d0
0.0 61.2 0.0 7.7 0.0 0.0 0.0 0.0 0 0
c2t60060160BE120F0019092094574FDC11d0.fp0
0.0 61.3 0.0 7.7 0.0 0.0 0.0 0.0 0 0
c2t60060160BE120F0019092094574FDC11d0.fp3

While the iostat output isn't quite as nice as what you get with
"vxdmpadm iostat ..." or "powert display ...", it does the job.
