For simpliﬁed I/O block diagrams of the LBA to physical slot

relationship, see Appendix A, “Hardware Path to Physical I/O Slot

Correspondence,” on page 117.

Assigning I/O at the LBA Level.

For our example computer, the ioscan output shows the LBAs as:

#ioscan -k | grep "Bus Adapter"

H/W Path Class Description

===========================================================

0/0 ba Local PCI Bus Adapter (782)

0/1 ba Local PCI Bus Adapter (782)

0/2 ba Local PCI Bus Adapter (782)

0/4 ba Local PCI Bus Adapter (782)

0/5 ba Local PCI Bus Adapter (782)

0/8 ba Local PCI Bus Adapter (782)

0/10 ba Local PCI Bus Adapter (782)

0/12 ba Local PCI Bus Adapter (782)

1/0 ba Local PCI Bus Adapter (782)

1/2 ba Local PCI Bus Adapter (782)

1/4 ba Local PCI Bus Adapter (782)

1/8 ba Local PCI Bus Adapter (782)

1/10 ba Local PCI Bus Adapter (782)

1/12 ba Local PCI Bus Adapter (782)

Looking at the full ioscan output to verify that we have the desired I/O

for each partition, we will assign the I/O at the LBA level. (When

assigning hardware at the LBA level to a partition, all hardware at and

below the speciﬁed LBA is assigned to the partition.):
