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.
The dynamic PCIe bus assignment feature is supported on servers starting with the SPARC M5, SPARC T5, and SPARC S7 series server and the Fujitsu M10 server that run the Oracle Solaris 11 OS in the root domain.
SPARC T5, SPARC M5 and SPARC M6 servers must run at least the 9.4.2 version of the system firmware. SPARC T7 and SPARC M7 series servers must run at least 9.4.3. SPARC S7, SPARC T8, and SPARC M8 series servers can run any released version of the system firmware. Fujitsu SPARC M12 servers can run any released version of the system firmware. Fujitsu M10 servers must run at least XCP2240.
