What kind of hardware? For emulated 3390's (such as Shark), a 'read check' does not make much sense. Most all such activity occurs in the cache. Real I/O errors are transparently handled in the hardware.
More reasonable might be a read past end of file, inappropriate DCB, a null file (VTOC entry only), logically corrupt file/database, etc. All programmer issues, not hardware. I did once see an error when one of the paths was taken offline.

I ran an ANALYZE (using parms SCAN SPEED) and "ALL DATA 'MACHINE READABLE' WITHOUT ERRORS". I executed an INSPECT and received a "FUNCTION COMPLETED, HIGHEST CONDITION CODE WAS 0". ...snip Should there be something else that I should try? Thanks in advance.
