9.3.6 Statically Releasing the PCIe Endpoint From a
Logical Domain
The operation of statically releasing the PCIe endpoint from a logical domain must be
performed from the control domain.
Before removing the PCIe endpoint, confirm that it is not being used by the logical
domain. For details, see the manual for the software being used.
For information on how resources are moved when the assignment of the PCIe
endpoint is statically released, see
Table 9-7
Table 9-7 Procedure for Statically Releasing a PCIe Endpoint
Step Operation Description
1 Checking the assignment status of
PCIe endpoints
2 Stopping the I/O domain assigned the
PCIe endpoint to be released
3 Releasing the PCIe endpoint assigned
to the I/O domain
4 Setting delayed reconfiguration for the
control domain or root domain
5 Assigning the released PCIe endpoint
to the control domain or root domain
6 Restarting Oracle Solaris on the
domain (control domain or root
domain) that is set for delayed
reconfiguration
7 Confirming that the PCIe endpoint
was released from the I/O domain
The following example executes the commands for releasing the PCIe endpoint
assigned to the logical domain io-domain.
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.
