The IBM vNIC protocol provides support for the user to initiate a failover from the client LPAR in case the current backing infrastructure is deemed inadequate or in an error state. Support for two H_VIOCTL sub-commands for vNIC devices are required to implement this function. These commands are H_GET_SESSION_TOKEN and H_SESSION_ERR_DETECTED. "[H_GET_SESSION_TOKEN] is used to obtain a session token from a VNIC client adapter. This token is opaque to the caller and is intended to be used in tandem with the SESSION_ERROR_DETECTED vioctl subfunction." "[H_SESSION_ERR_DETECTED] is used to report that the currently active backing device for a VNIC client adapter is behaving poorly, and that the hypervisor should attempt to fail over to a different backing device, if one is available." To provide tools access to this functionality the vNIC driver creates a sysfs file that, when written to, will send a request to pHyp to failover to a different backing device.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
