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

Workaround: You can ignore unexpected telemetry faults. To clear the fault, perform these steps:
Type the fmadm faulty command to obtain the fault UUID.
# fmadm faulty ------------------- --------------------------------- -------------- -------- Time UUID msgid ... Severity ------------------- ---------------------------------- ---------------------- 2012-10-04/17:24:07 87732365-faa6-e9cd-bf2a-9052cb8cf876 SUNOS-8000-J0 Major
Clear the unexpected telemetry fault in the Oracle Solaris host using the fault UUID.
