*1 Dynamic reconfiguration of the root complex is supported by XCP 2240 or later and Oracle VM Server for
SPARC 3.2 or later. In addition, the control domain must be Oracle Solaris 11.2 SRU 11.2.8 or later.
*2 If dynamic reconfiguration of the root complex is not used, set the control domain to delayed reconfiguration,
and then delete the physical I/O device.
1. Transition the control domain to delayed reconfiguration mode.
If you are dynamically reconfiguring the root complex, this step is unnecessary.
Go to step 2.
# ldm start-reconf <control domain name>
2. Delete the physical I/O device from the control domain.
# ldm remove-io <physical I/O device name> <control domain name>
3. Restart the control domain.
If you are dynamically reconfiguring the root complex, this step is unnecessary.
# shutdown -i6 -g0 -y
Note - When set to delayed reconfiguration mode, the control domain does not have control
over the guest domains. If you have set the control domain to delayed reconfiguration mode,
restart the control domain as soon as possible.

Enabling the removal of an I/O device

This section describes the procedure for enabling the removal of an I/O device by
using the hot plug function.
To use the hot plug function, the hotplug service of Oracle Solaris needs to be
enabled. Check the status of the service. If it is disabled, enable the hotplug service in
the following procedure. The hot plug function is available only on the control
