Determine whether PHP can be used, combining the two pieces of information
described above based on the confirmation results obtained in step 5.
- Suppose that both of the logical domains to which the PCIe slot and the PCIe
root complex 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 )
- Suppose that both of the logical domains to which the PCIe slot and the PCIe
root complex are assigned are found not to be a control domain but the same
logical domain (root domain). In this case, active/hot maintenance can be
performed using PHP from the root domain. (*7 in Figure 13-2 )
- In cases other 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
maintenance procedure. (*6 and *8 in Figure 13-2 )
