For a quick overview of setting up MPxIO and the other configs:

This output allows you to select your particular fibre paths to ensure that
you aren't selecting fibre devices you don't wish to multipath.
[EMAIL PROTECTED]:~]# luxadm -e port

/devices/[EMAIL PROTECTED],600000/SUNW,[EMAIL PROTECTED]/[EMAIL

Leave the MPxIO disable to yes to keep local disks out of management. Cut down
the luxadm -e port output in the format below (keep path, cut port).

it off, in which case change the option to "none".
