The dynamic PCIe bus assignment feature enables you to dynamically assign or remove a PCIe bus from a root domain.
The dynamic PCIe bus assignment feature is enabled when your system runs the required firmware and software. See Dynamic PCIe Bus Assignment Requirements. If your system does not run the required firmware and software, the ldm add-io and ldm remove-io commands fail gracefully.
When enabled, you can run the ldm add-io and ldm remove-io commands without stopping the root domain or putting the root domain in delayed reconfiguration.
To use the dynamic PCIe bus assignment feature, you must meet the software and firmware requirements for the Oracle VM Server for SPARC 3.2 release.
This feature is supported on SPARC M5, SPARC M6, and Fujitsu M10 platforms.
