scxi_scan error : scan_opt() not successful

[Rich_G]

A vintage application started returning (( scxi_scan error : scan_opt() not successful )).

The program has tested over 500,000 parts in the last 2 years.

I have replaced the 8186 controller and the 2, 1104C scxi cards.

I have reloaded the drivers, and restored the hdd image from last week.

I went so far as to replace the pxi chassis.

I am still receiving this error.

Does any one have a clue what is happening ???

I found the fault. The 6052E was not providing the Scan Clock.
