I followed your below suggestion so global parameter is a 2nd one - no
difference however and now even local disks are not under MPxIO.

I disconnected one SAS cable, if I connect it then 2530's luns will
appear twice as c2t2dN
I included prtconf -pv output

So I changed the order:
# grep -v "^#" /kernel/drv/mpt.conf
tape="sctp";
ddi-vhci-class="scsi_vhci";
name="mpt" parent="/[EMAIL PROTECTED],0/pci8086,[EMAIL PROTECTED]"
unit-address="0" mpxio-disable="yes";
mpxio-disable="no";
And still I got 'pcie_pci: [ID 291552 kern.warning] WARNING: [EMAIL PROTECTED]:
mpt.conf properties not merged' and nothing isunder MPxIO.

Usually it is. On SPARC with -10 it was just that.
Here I got -14 - maybe that's a problem?
