Goal

NOTE: FPScrubber comes installed on Solaris 10 5/09 (Update 7) and above.

FPScrubber is a service that actively checks to verify the FPU is functioning correctly. In doing so, it schedules tests such that the system load is minimal and won't interrupt any power saving functions.

FPScrubber is composed of the following:

    * fpsd : an SMF daemon that runs in the background of Solaris
    * fptest : the binary that does the actual testing
    * fps-transport : FMA module that relays the ereport payload from fptest
    * cpumem-diagnosis : FMA module that can offline a CPU that has a malfunctioning FPU

The process begins by fpsd scheduling the fptest to run on a CPU ID. Fptest then begins a series of tests on that CPU ID. If any errors are found, fptest will generate an ereport payload and send it to the fps-transport module through a sysevent channel. Once there, it's recorded in the FMA logs, and the cpumem-diagnosis engine will attempt to offline that CPU ID.

The testing continues such that every CPU ID gets tested at every test stress level within 24 hours.
    

Solution

Installation:
The fpscrubber daemon is found in packages: SUNWfsu, SUNWfsr and SUNWfmd.

Usage:
It supports the following CPUs:

    * UltraSPARCIII
    * UltraSPARCIIIi
    * UltraSPARCIII+
    * UltraSPARCIV
    * UltraSPARCIV+


To disable:
# svcadm disable svc:/system/fpsd

To enable:
# svcadm enable svc:/system/fpsd

Additional information can be found in the fpsd(1M) man page.
To view any logs, use the fmdump utility.
See the man page fmdump(1M).
