which IOAs are 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.
