Determinew hether PHPcan be used, combin ing the two pieces of information
describedabove based on the confirmation results obtained in step 5.
- Supp ose that both of the logical domains to which the PCIe slot and the PCIe
rootcomplex are assigned are found to be a control domain (primary). In this
case,active/hot maintenance can be performed using PHP from the control
domain.(*5 in Figure 13-2)
- Supp ose that both of the logical domains to which the PCIe slot and the PCIe
rootcomplex are assigned are found not to be a control domain but the same
logicaldomain (root domain). In this case, active/hot maintenance can be
performedusing PHP from the root domain. (*7 in Figure 13-2)
- In ca seso ther than the above (those where the domains are found to be I/O
domains),PHP cannot be used. Thus, see Table 13-4 for an appropriate
maintenanceprocedure. (*6 and *8 in Figure 13-2)
