For information about how to work around the limitations, see Planning PCIe Endpoint Device Configuration.
Assignment or removal of a PCIe endpoint device to any non-root domain is permitted only when that domain is either stopped or inactive.
For up-to-date information about this feature, see Fujitsu M10/SPARC M10 Systems System Operation and Administration Guide for your model at http://www.fujitsu.com/global/services/computing/server/sparc/downloads/manual/.
SPARC systems, up to and including the SPARC T5 and SPARC M6 platforms, provide a finite number of interrupts, so Oracle Solaris limits the number of interrupts that each device can use. The default limit should match the needs of a typical system configuration but you might need to adjust this value for certain system configurations. For more information, see Adjusting the Interrupt Limit.
