1.4.3 Reconfiguration of a Physical I/O Device


1.4.3 Reconfiguration of a Physical I/O Device
Adding or deleting a physical I/O device
The need for dynamic reconfiguration of each physical I/O device differs depending on the version of Oracle VM Server for SPARC. For details, see "Table 1-2."
  1. Before adding or deleting a physical I/O device in the control domain, you need to enter delayed reconfiguration mode.
  2. Before adding or deleting a physical I/O device in the root domain, you need to enter delayed reconfiguration mode or shut down the root domain (ldm stop-domain).
  3. Before adding or deleting a physical I/O device in an I/O domain, you need to shut down the I/O domain (ldm stop-domain).
Device driver
Drivers that control physical I/O devices in a physical partition that will be dynamically reconfigured must support the suspend and resume functions of Oracle Solaris.
Supporting SR-IOV
When combined with Oracle VM Server for SPARC, the SPARC M12/M10 can support the PCIe SR-IOV function (single root I/O virtualization function).
With the SR-IOV function, you can create multiple virtual functions for one physical function by using a PCI Express card that supports SR-IOV. Assigning created virtual functions to I/O domains allows logical domains to share PCIe card bands more efficiently, resulting in reduced overhead for the service domain. For details on the SR-IOV function, see the Oracle VM Server for SPARC Administration Guide and the PCI Card Installation Guide for your server. In addition, for the available Oracle Solaris versions, see the Oracle VM Server for SPARC Release Notes and the Oracle VM Server for SPARC Administration Guide.
