I/O

For detailed information on I/O Assignments, see “I/O: Allocation Notes” on page 242.

For simpliﬁed I/O block diagrams of the LBA to physical slot relationship of PA-RISC systems, see

Appendix A, “LBA Hardware Path to Physical I/O Slot Correspondence (PA-RISC only),” on page 347.

Assigning I/O at the LBA Level

Looking at the full ioscan output to verify that we have the desired I/O for each virtual 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.)

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

keira#ioscan -k | grep “Bus Adapter”
