Resilient I/O Domain Requirements

    A resilient I/O domain must meet the following requirements:

  • Runs at least the Oracle Solaris 11.2.8.0.0 (SRU 8) OS and its primary domain runs at least the Oracle VM Server for SPARC 3.2 software.

  • Uses multipathing to create failover configurations for virtual functions and virtual devices. For network multipathing, the IPMP group can have virtual functions and vnet devices.

  • Has the master property value set to the name of a root domain whose failure-policy property is set to ignore. Any other failure policy setting, such as stop, reset, or panic, supersedes I/O resiliency and the I/O domain is interrupted.

  • Uses only SR-IOV virtual functions that support I/O domain resiliency. See https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=REFERENCE&id=1325454.1.


Note - If the I/O domain only uses I/O-resilient devices but does not configure multipathing, the applications are impacted until the root domain returns to service and the affected devices are restored.
