Procedure for Statically Releasing a PCIe Endpoint
Step Operation Description Execution Location Command Used
1 Checking the assignment status of
PCIe endpoints
Control domain primary# ldm list-io
2 Stopping the I/O domain assigned the
PCIe endpoint to be released
Control domain primary# ldm stop-domain <domain-name>
3 Releasing the PCIe endpoint assigned
to the I/O domain
Control domain primary# ldm remove-io <device> <domain-
name>
4Setting delayed reconfiguration for the
control domain or root
domain
Control domain primary# ldm start-reconf <domain-name>
5 Assigning the released PCIe endpoint
to the control domain or root domain
Control domain primary# ldm add-io <device> <domain-name>
6 Restarting Oracle Solaris on the
domain (control domain or root
domain) that is set for delayed
reconfiguration
Control domain
When delayed reconfiguration has been set
for
the control domain
primary# shutdown -i6 -g0 -y
When delayed reconfiguration has been set
for the root domain
primary# ldm stop-domain -r <domain-name>
7Confirming that the PCIe endpoint
was released from the I/O domain
Control domain primary# ldm list-io
primary#
ldm list-io

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 Figure 9-3.
Table 9-7 lists the procedure for statically releasing a PCIe endpoint.
The following example executes the commands for releasing the PCIe endpoint
assigned to the logical domain io-domain.
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.
