Validate and Verify Data After SAN Migration
I'd compare the data using, say, Red Gate SQL Data Compare in addition to DBCC.
Comparing all data in all tables row by row means checking every populated page.

However, for larger databases this will a long time, so you can run aggregates over columns (say AVG or CHECKSUM_AGG). I use this to quickly compare results but it would scale and force data to be read.
