...pecial command is sent. In older kernels, layers like the partition scanning and udev and hal would send down IO to those disabled paths and we would see IO errors like in your link. In newer kernels we have device handler modules (for MD3000i you would want scsi_dh_rdac (so do "modprobe scsi_dh_rdac" and then lsmod to see if it is there)) that will detect if the path is not active and if so it will either not send the IO or it will not print a error message since we expect the IO to fail. We'd prefer *not* seeing spurious I/O...
