Note:

The following table provides information necessary to identify the IOP to which an IOA is assigned.

The left column indicates the domain in which IOA assignment is allowed.
The right column is used to determine the IOP to which an IOA is assigned.

The first position in the list must be an IOP. The remaining positions may be IOPs or IOAs. IOAs are assigned to the first IOP located to their left in the list. Although IOAs can be manually reassigned using SST/DST, the IOA assignments return to the default order after each IPL.
