The following example executes the commands for releasing the PCIe endpoint from
logical domain guest to allow the PCIe card to be replaced.
1.
Check the assignment status of PCIe endpoints to logical domains.
In this example, PCI slot #5 of the SPARC M12-2S of BB-ID#01 is assigned to the
logical domain
guest.
2.
Release the PCIe endpoint from the logical domain.
Release PCI slot #5 of the SPARC M12-2S of BB-ID#01 from the logical domain
guest.
3.
Return the released PCIe endpoint to the control domain or root domain.
To remove a PCIe card or release a root complex by the PCI Hot Plug function,
you need to return the PCIe endpoint to the control domain or the root domain
beforehand.
Return PCI slot #5 of the SPARC M12-2S of BB-ID#01 to the control domain.
4.
Confirm that the target PCIe endpoint has been returned to the control
