Releasing The Assignment Of I/O Devices - Fujitsu M10-4 Service Manual

5.4.1

Releasing the assignment of I/O devices

This section describes the work to be done before maintenance using PCI hot plug
(PHP) or dynamic reconfiguration (PPAR DR) of the physical partition.
When using PCI hot plug (PHP)
■
If the PCIe end point of the PCIe card requiring maintenance is assigned to an I/O
domain or if the SR-IOV virtual function is assigned, return the PCIe end point to
the root or control domain.
(1) Stopping the use of an I/O device
(2) Deleting the assignment of an I/O device
When using dynamic reconfiguration (PPAR DR) for the physical partition
■
If the PCIe end point of the PCIe card in the chassis requiring maintenance is
assigned to an I/O domain or if the SR-IOV virtual function is assigned, return the
PCIe end point to the root or control domain. Then, remove the root complex from
the root or control domain.
(1) Stopping the use of an I/O device
(2) Deleting the assignment of an I/O device
(3) Deleting the root complex
(1) Stopping the use of an I/O device
If there is any logical domain that is physically or virtually using the PCIe card
mounted in the chassis requiring maintenance, stop the use of the I/O device to keep
it unused.
With a redundant configuration, use the duplication function to release the target I/O
device so that it will not be used. For details on the work, see the manual for the
application being used.
With a non-redundant configuration, place the I/O device in the unused state, such as
by deactivating the network or unmounting the disk to stop the use. For details on
the work, see the Oracle Solaris documents and the manual for the application being
used.
(2) Deleting the assignment of an I/O device
When using virtual I/O
When using a virtual I/O service, delete the virtual I/O device. For details, see the
Oracle VM Server for SPARC Administration Guide from Oracle.
The following is a command execution example for deleting the virtual disk
(vdisk11) and virtual network device (vnet10) that use the virtual I/O service of the
control domain or root domain.
