How can I check that a reserve is on?

As a workaround, I have disabled the fscsi1 path on VIOA server and it I don't see any errors. However, I noticed all I/O's going thru just 1 path (path0) of the adapter (fscsi3) .
I was expecting the I/o to be balanced between Path0 and Path2 for hdisk3 .

Any thoughts ?

Code:
