Users: sparmaintainer@unisys.com What: install/boottotool Date: 7/18/2014 KernelVersion: TBD Contact: sparmaintainer@unisys.com Description: The boottotool flag controls s-Par behavior on the next boot of this guest. Setting the flag will cause the guest to boot from the utility and installation image, which will use the value in the toolaction field to determine what operation is being requested. Users: sparmaintainer@unisys.com What: install/toolaction Date: 7/18/2014 KernelVersion: TBD Contact: sparmaintainer@unisys.com Description: This field is used to tell s-Par which type of recovery tool action to perform on the next guest boot-up. The meaning of the value is dependent on the type of installation software used to commission the guest. Users: sparmaintainer@unisys.com What: parahotplug/deviceenabled Date: 7/18/2014 KernelVersion: TBD Contact: sparmaintainer@unisys.com Description: This entry is used by a Unisys support script installed on the guest, and triggered by a udev event. The support script is responsible for enabling and disabling SR-IOV devices when the PF device is being recovered in another guest. Some SR-IOV devices have problems when the PF is reset without first disabling all VFs attached to that PF. s-Par handles this situation by sending a message to guests using these VFs, and the script will disable the device. When the PF is recovered, another message is sent to the guests to re-enable the VFs. The parahotplug/deviceenabled interface is used to acknowledge the recovery message.
