In Some Cases, Spurious Faults of Type fault.sunos.eft.unexpected_telemetry Are Reported (15820471)

A device reporting a large number of correctable errors continues to report errors while it is being disabled. Each error is queued and diagnosed in order. In rare cases, the last error reported by the device might be queued but not processed for diagnosis until after the device is disabled. This last error is reported as unexpected telemetry, because the device is no longer enabled in the system.

For example:

# fmadm faulty

An unexpected telemetry fault in this case can be safely ignored.

Workaround:

1. Use the fmadm faulty command to obtain the fault UUID. For example:

   # fmadm faulty
   ------------------- ------------------------------------ -------------- 
   Time                UUID                                 msgid 
   ...

2. Clear the unexpected telemetry fault in the Oracle Solaris host using its UUID. For example:

   # fmadm repair 87732365-faa6-e9cd-bf2a-9052cb8cf876
