Oracle Database - Enterprise Edition - Version 9.2.0.8 to 11.2.0.4 [Release 9.2 to 11.2]
Information in this document applies to any platform.

Symptoms

ORA-1578 or transient corruption using EMC DX4 storage.

Subsequent runs of RMAN would find different blocks corrupted

 
However, subsequent runs of the application process would find valid data (reflecting the transient nature of the corruption).

Also  at the exact minute ( in ten minutes intervals 4, 14, 24, 34, 44, 54 on the hour) when the corruption was reported, it was nearly always detected on more than one server.  It was the same type of corruption just different blocks.
