Hello --
Solaris 8
Sunfire V890
SVM for our boot disk
======================
We currently use MPXIO to multipath to our EMC devices.
With the V890 we now have 6 internal disks with an internal controller.
I want to use MPXIO to manager my local disks ( boot disk included ) and
take advantage of the ability to "split" the controllers.
my internal controllers are c1 and c2 -- pointing to same device
FORMAT with no MPXIO:
0 & 6 are the same device
1 & 7 are the same device
etc...
